New Starter App

ButterCMS is designed to be easy to integrate into your existing Flutter project. If you are starting from scratch, check out this Flutter + ButterCMS Starter that you can use to instantly launch a Flutter site that's fully integrated with ButterCMS.

https://github.com/ButterCMS/buttercms-flutter-example

Add Butter to An Existing App

Add this line as dependency in pubspec.yaml

buttercms_dart: ^0.1.0

The Dart SDK source code is available on Github.

First, create a Flutter project on your preferred editor.

Next, add the package dependency in pubspec.yaml as described in the Install section.

Creating the ButterCMS client

First create a Butter object:

// Initialising Butter
Butter butter = Butter("YOUR_API_KEY");

// OR

var butter = Butter("YOUR_API_KEY");

Then run:

butter.post.list().then((response) {
print(response.body);
});

This API request fetches our blog posts. Your account comes with one example post which you'll see in the response. If you get a response it means you're now able to connect to our API.

Introduction

Quickly launch a new marketing site or add CMS-powered pages to your existing site using our Pages. To create dynamic landing pages be sure to check out Components.

Create a Single Page

GET https://api.buttercms.com/v2/pages/*/?auth_token=your_token

Adding a CMS-powered page to your app involves three easy steps:

1. Create the Page structure
2. Populate the content
3. Integrate into your application

If you need help after reading this, contact us via email or livechat.

Create the Page Structure

The first step is to create a new Page and define its structure using our Page Builder.

Let's create an example homepage. For the "Customer Logos" field, we'll use a repeater, which will later make it easy to loop through this field in our template.

Populate the Content

Choose a title and API slug.

Now, let's populate our new page with content. In the next step, we'll call the ButterCMS API to retrieve this content from our app.

Integrate into your application

With your homepage defined, the ButterCMS Pages API will return it in JSON format like this:

{
  "data": {
    "slug": "homepage",
    "name": "HomePage",
    "published":"2021-08-20T15:06:58.237911Z",
    "updated":"2021-08-20T15:06:58.237911Z",
    "page_type": null,
    "fields": {
      "seo_title": "Anvils and Dynamite | Acme Co",
      "headline": "Acme Co provides supplies to your favorite cartoon heroes.",
      "hero_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV",
      "call_to_action": "Buy Now",
      "customer_logos": [
        {
          "logo_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV"
        },
        {
          "logo_image": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV"
        }
      ]
    }
  }
}

To integrate this into your app, import and create a Butter client :

import 'package:buttercms_dart/buttercms_dart.dart';

// Inside class
Butter butter = Butter("YOUR_API_KEY");

The butter client allows us to fetch a single page using the retrieve() function call.

Create the component home_page.dart:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class HomePage extends StatefulWidget {
 @override
 _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State {
 Butter butter = Butter("YOUR_API_KEY");

 Map jsonMap;

 @override
 void initState() {
   super.initState();
   butter.page.retrieve("*", "homepage").then((response) {
     setState(() {
       // First fetch the json response,then decode into a map
       jsonMap = json.decode(response.body);
     });
   });
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text("Home Page"),
     ),
     body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
   );
 }

 Widget _buildLoadingScreen() {
   return Center(
     child: CircularProgressIndicator(),
   );
 }

 Widget _buildBody() {
   return ListView(
     children: [
       Padding(
         padding: const EdgeInsets.all(8.0),
         child: Text(jsonMap["fields"]["seo_title"]),
       ),
       Padding(
         padding: const EdgeInsets.all(8.0),
         child: Text(jsonMap["fields"]["headline"]),
       ),
       Padding(
         padding: const EdgeInsets.all(8.0),
         child: Image.network(jsonMap["fields"]["hero_image"]),
       ),
       Padding(
         padding: const EdgeInsets.all(8.0),
         child: FlatButton(
           onPressed: () {},
           child: Text(
             jsonMap["fields"]["call_to_action"],
           ),
         ),
       ),
       Padding(
         padding: const EdgeInsets.all(8.0),
         child: Text("Customers love us!"),
       ),
       ...jsonMap["customer_logos"]
           .map((logo) => Image.network(logo["logo_image"]))
           .toList(),
     ],
   );
 }
}

That's it! If you browse to your homepage you'll see your homepage populated with the content you created in Butter.

Create multiple pages using Page Types

Overview Video

Step By Step Tutorial

Let's say you want to add a set of Customer Case Studies to your marketing site. Each should have the same structure, but different content. Page Types are a perfect tool for this scenario.

You can create a Page Type from scratch in four easy steps:

1. Create A Single Page
2. Populate Your Page Content
3. Create a Page Type From Your Page
4. Integrate into your application

Any Single Page that you've created can be used to create a Page Type by starting with Step #3: Create a Page Type From Your Page.

If you need help after reading this, contact us via email or livechat.

Create A Single Page

You'll start with creating a new Single Page, which will eventually be your first Customer Case Study. You'll later use the structure, or schema, of this first page to form the basis of the Customer Case Study Page Type. Once you've finished setting up your schema, click "Save to edit the page content."

Note: You can also add create, edit, and delete Page Types via the new Content Types Pane. Adding Page Types this way doesn't require the creation of a Single Page first, as you will directly create and access the Page Type schema. Once you've created your new Page Type, you can hover over the Pages menu in the Butter sidebar and click the plus sign next to your new Page Type to create a Page of that Type!

Populate the Content

After saving, you'll be asked to assign a title for the page. For this first Customer Case Study, we'll use "Acme Co." Assigning a title automatically generates a slug for this page that we'll later use to retrieve it from our app via the ButterCMS API:

Now, click on "Save Page Metadata" and populate content for "Acme Co", your first Customer Case Study.

Create a Page Type From Your Page

Now, we're going to create a Customer Case Study Page Type from our Acme Co case study, which will allow us to reuse this page structure across multiple Customer Case Study pages.

First, publish or save the Acme Co page. Then, click the three dots in the upper right-hand corner of the page and click on "edit schema."

This brings you back to the initial Page Configuration view. Click on the button in the top right that says Create Page Type.

Give your new page type a name. This auto-generates the API slug needed to call this Page Type from the ButterCMS API.

Integrate into your application

With a case study defined, the ButterCMS Pages API will return it in JSON format like this:

{  
  "data": {
    "slug": "acme-co",
    "name": "Acme Co",
    "published": "2021-08-23T14:28:21.077112Z",
    "updated": "2021-08-23T14:28:21.077112Z",
    "page_type": "case_study",
    "fields": {
      "seo_title": "Acme Co Loves Butter CMS",
      "seo_description": "Acme Co saved 200% on Anvil costs with ButterCMS",
      "headline": "Acme Co saved 200% on Anvil costs with ButterCMS",
      "facebook_open_graph_title": "Acme Co Customer Case Study",
      "customer_logo": "https://cdn.buttercms.com/66oMGYOuSP2V0bsK6gKd",
      "testimonial": "<p>We've been able to make anvils faster than ever before!<em>--Chief Anvil Maker Anvil</em></p>
      <p><img src="https://cdn.buttercms.com/queOG6fITpiJAUc7GV30\" alt="" /></p>"""
    }
  }
}

Setup the Customers Page to list all our customers

The plugin also allows us to retrieve multiple pages using list() instead of retrieve().

We will try to list multiple client pages as:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class PagesListScreen extends StatefulWidget {
@override
_PagesListScreenState createState() => _PagesListScreenState();
}

class _PagesListScreenState extends State {
Butter butter = Butter("YOUR_API_KEY");

Map jsonMap;

@override
void initState() {
  super.initState();
  butter.page.list("case_study").then((response) {
    setState(() {
      // First fetch the json response,then decode into a map
      jsonMap = json.decode(response.body);
    });
  });
}

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text("Pages"),
    ),
    body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
  );
}

Widget _buildLoadingScreen() {
  return Center(
    child: CircularProgressIndicator(),
  );
}

Widget _buildBody() {
  List pages = jsonMap["data"];

  return ListView.builder(
    itemBuilder: (context, position) {
      return ListTile(
        title: Text(pages[position]["fields"]["headline"]),
        leading: Image.network(
          pages[position]["fields"]["customer_logo"],
          width: 40.0,
          height: 40.0,
        ),
      );
    },
    itemCount: pages.length,
  );
}
}

That's it! The page your created in Butter dashboard will immediately show in your app.

Dynamic landing pages using Components

Modeling Complicated Content

The Pages in the above examples use fairly simple content models. Simple can be great, like when you need to create a number of basic pages with the exact same structure and layout. But what about when your marketing team wants to create a wide array of landing pages with differing layouts?

That's where Butter Components come in. Components are user-defined partial schemas and come in two main varieties: Local Components, which are defined inside of the Page or Page Type schema, and Global Components, which can be saved/accessed via the global Component Library in the Content Types Pane for maximum reusability.

In addition to normal component fields, users can also create Component Pickers. When added to a Page, component pickers allow content creators to choose from a palette of pre-defined local or global components.

For more details, including how to set up dynamic pages in Butter with flexible, tailored layouts, check out our detailed documentation on Components, including Local Components, Global Components, and Component Pickers.

Collaborate with marketing when defining your Component Library

When using Components, collaborate with your marketing team to define a library of Components (i.e. SEO, Call to Action, Hero, Key Benefits, etc) that your team will use to compose pages. Once you've defined this Component library, your marketing team will have a good understanding of what Components are available to them as they launch new campaigns.

Previewing Pages

To give your marketers the ability to preview pages you will want to first configure the preview URL of your Page Type.

When your marketer clicks "Preview", they will get taken to that preview URL such as https://yoursite.com/the-page/?preview=1 with a preview=1 parameter appended.

Your application will then look for that preview=1 parameter and when detected, call the ButterCMS API with the same preview parameter. You can see this defined in our API docs when querying Pages.

Passing preview=1 to ButterCMS will cause the draft version of the Page content to be returned and thus displayed within your application, allowing your marketing team to see a full in-context preview of their draft changes.

For frameworks that don't allow dynamic real-time routing, like Astro, Hugo, and static-site generators, you can set the preview value as an environment variable and pass that in a parameters array when making your call to Butter. See our Astro starter for an example.

Introduction

The Content Types Pane, which can be accessed via the below icon in the Butter Dashboard, allows for easy, one-click access to viewing and editing user-defined content, including Global Components, Collections, and Page Types.

Features Of The Content Types Pane

The Content Types Pane offers convenient access to a number of features. To see them in action, check out the animation below.

• Create new Page Types, Global Components, and Collections with a single click.
• Integrated Search: Can't remember if your SEO block is a Page Type, a Global Component, or Collection? The Content Types Pane allows you search through all three at once, or filter by a specific Content Type.
• Easy Schema Updates: Clicking on any named Content Type from within the Content Types Pane takes you directly to the schema for that object, allowing for lightning-quick updates!

As you can see, the Content Types Pane is a powerful tool to make creating, editing, and deleting your custom user content a breeze! If you need help after reading this, contact us via email or livechat.

Introduction to Components

Butter Components are user-defined partial schemas and come in two main varieties: Local Components, which are defined inside of the Page or Page Type schema, and Global Components, which can be saved/accessed via the global Component Library in the Content Types Pane for maximum reusability.

In addition to normal component fields, users can also create Component Pickers. When added to a Page, component pickers allow content creators to choose from a palette of pre-defined local or global components.

Components allow you to:

• Group data by function: For example, all of the data relating to the SEO of your Page might be lumped together into a single SEO component, making it much easier for marketers to find.
• Group data by structure: You could create a component in Butter for a Hero Banner that includes all of the relevant fields, such as a title, a call to action button, a featured image, links, and even design elements like hex values for color. You could then save this component as a Global Component, which could then be imported from your Component Library and included in the schemas for other Page Types.
• Create flexible, dynamic layouts for pages via the usage of a Component Picker that chooses from pre-defined components. This makes piping the data into templates and apps easy, as the data will match the structure you and your development team have defined.
• And, in the case of a Global Component, easily make changes that automatically update multiple Pages and Page Types.

For more details, including how to use Local Components, Global Components, and Component Pickers, refer to the examples below!

Local Components

A Component Field, like the one above, represents a single Local Component. When setting up either a Local or Global Component, you can mix-and-match from the following Content Field Types:

• Short Text
• Long Text
• WYSIWYG
• Date
• Dropdown: (Tip: Hit [enter] to add new values)
• Media: Utilizes the filestack API to serve and transform images, video, and more via our lightning-fast CDN. For more information, see Image Transformation.
• Checkbox
• Number
• HTML: Useful to add additional code snippets, etc.
• Repeater: A content field that allows you to group any combination of the above fields. Useful for creating testimonial slides, image slides for a carousel, etc.
• Reference: A powerful field type that allows to link to your other content, such as Pages and Collections. See this blog entry for more information.

Each Content Field has a number of additional configuration options that can be accessed via the settings gear in the top right corner of each Field instance, such as marking fields mandatory, setting minimum and maximum character counts, or adding rollover help text to assist your marketing team.

As mentioned in the introduction, a Component can be used to group related fields of a Page together. For example, configuring an SEO Component on your Page is a great idea to give your marketers the control they need over SEO and social sharing meta tags.

Here is how to create a local SEO component inside a new Page schema:

Once the schema is set, marketing is ready to add content to the Page. This is what the finished component looks like when the Page is accessed.

The content for a Component is serialized as you would expect, an object within the larger Page fields object.

{
    "data": {
        "slug": "homepage",
        "fields": {
            "seo": {
                "seo_title": "...",
                "meta_description": "...",
                "opengraph_title": "...",
                "opengraph_image": "https://cdn.buttercms.com/..."
            }
        }
    }
}

Global Components

You can save any Local Component to your Content Library, where it can then be accessed via your Content Types Pane:

We can tell that this component is now a Global Component by the book icon in the top right corner of the Page Schema:

In addition to converting local components via the "Save to Library" button, Global Components can also be created directly by clicking the plus sign icon next to "Components" in the Content Types Page. Components created this way will also be available in the Component Library.

New Feature: Component Thumbnails

You can now upload thumbnails and add descriptions to your global components!

Thumbnails make it easier for your marketing team to find the component they need in your Component Library or in Component Pickers like the ones in the next section.

Component Pickers

A Component Picker defines a palette of Components your marketing team can use when composing a page. Pickers can be local (defined in a Page or Page Type schema) or global (added to the Component Library.) Above is a Component Picker named "Sections" (to represent horizontal sections of a page) that contains two Components inside of its schema. Below, you can see the Component Picker in action!

Our component pickers now feature drag-and-drop reordering for fast updates.

Component Pickers allow your marketing team to compose a new page by mix-and-matching the Components defined in the schema in any order they choose. For example...

Your Homepage could be composed of these Components...

• Hero
• Call to Action
• Key Benefit

While your Solutions page uses these Components:

• Hero
• Call to Action
• Solution Details
• Call to Action

By using Component Pickers, marketers can create limitless combinations of landing pages, all without needing to involve your dev team.

Component Pickers are serialized arrays of Components within the larger Page fields object. Each item in the array has fields and type properties. So a Component Picker named sections would look like this:

{
  "data": {
    "slug": "homepage",
    "fields": {
      "sections": [
        {
          "fields": {
            "headline": "...",
            "subheadline": "...",
            "call_to_action": "..."
          },
          "type": "hero"
        },
        {
          "fields": {
            "video_headline": "...",
            "video_link": "..."
          },
          "type": "product_video"
        }
      ]
    }
  }
}

Here's the logic to render a page template in your application using a Component Picker.

  //Pseudocode
  For each component in sections:
  if type is 'hero':
    render hero.html template with template data/context set to component.fields
  if type is 'product_video':
    render product_video.html template with template data/context set to component.fields

  // Code
  for component in page.fields.sections:
    if component.type == 'hero':
      render('components/hero.html', { data: component.fields })
    if component.type == 'product_video':
      render('components/product_video.html', { data: component.fields })

Introduction

GET https://api.buttercms.com/v2/content/your_collection_key/?auth_token=your_token

Collections are tables of data to be referenced by Pages, extending the use cases that you can achieve with ButterCMS. They can be accessed in a variety of ways:

• Directly via the Collections Menu (see below), where you can create, edit, and delete both Collection schemas and individual Collection Items.
• Collection schemas can also be accessed via the Content Types Pane.
• Collection Items for existing Collections can also be created, edited, and queried directly from the Butter API. (For code examples of making API calls to query a Collection directly, check out our Collections API Reference.)

See the Collections Use Cases below. Several of these use cases utilize References. References are a powerful field type you can add to Pages and Collections that allow you to create links between your content.

Use Cases

• Tables of Related Content
• Page Facets to Group/Filter By
• Reusable Promotional Page Content

Tables of Related Content

There are many use cases for Collections. One is using Collections as tables of related data which you can query directly. For example, let's say you want to create a music site for musicians, and you want to store data like Albums and Artists.

Here's how you'd model that out using Collections in Butter and then query your content.

First, go to your collections dashboard. Click New Collection. (Alternatively, you could hover over the button for Content Types and click the plus sign next to "Collection.")

Configure this collection's properties to be "Name," "Headshot," and "Genre."

Give the collection the name "Artists" and save.

Let's add some Arists to the Collection.

Your collections dashboard should now look like this:

You can query Collections directly via our API. Here's what the API JSON response looks like for your Artists Collection.

GET https://api.buttercms.com/v2/content/artists/

{
    "data": {
        "artists": [
            {
                "genre": "Rap",
                "name": "Drake",
                "headshot": "https://cdn.buttercms.com/V0mLWb47TaI9qmrRkzAC"
            },
            {
                "genre": "Country",
                "name": "Carrie Underwood",
                "headshot": "https://cdn.buttercms.com/FRToQffDSK2IE1O3fUuq"
            },
            {
                "genre": "Rock",
                "name": "Young the Giant",
                "headshot": "https://cdn.buttercms.com/jqVWtHf6T6acW8APrh3g"
            }
        ]
    }
}

With your Artists Collection created, you can now create a Collection for Albums, which will include a Reference to our Artists Collection (as every Album belongs to an Artist). Start by creating a new collection.

Set up your configuration, with fields for "Album Name," "Artist," "Release Date," and "Cover Art." For "Artist," make sure to use a "Reference" field, link it to "Artists," and set the radio button to "One-to-Many."

Name your collection "Albums" and publish it.

Now, let's add some albums.

Here's what your Albums Collection should look like now:

Here's what the API JSON response looks like for your Albums Collection. Note artist is a Reference the Artists Collection above.

GET https://api.buttercms.com/v2/content/albums/

{
    "data": {
        "albums": [
            {
                "release_date": "2018-06-29T00:00:00",
                "artist": {
                    "genre": "Rap",
                    "name": "Drake",
                    "headshot": "https://cdn.buttercms.com/V0mLWb47TaI9qmrRkzAC"
                },
                "cover_art": "https://cdn.buttercms.com/uorkxsTQfit8N8uW6Im4",
                "album_name": "Scorpion"
            },
            {
                "release_date": "2018-09-14T00:00:00",
                "artist": {
                    "genre": "Country",
                    "name": "Carrie Underwood",
                    "headshot": "https://cdn.buttercms.com/FRToQffDSK2IE1O3fUuq"
                },
                "cover_art": "https://cdn.buttercms.com/3m0oGGyXQNCUnQke4Ps5",
                "album_name": "Cry Pretty"
            },
            {
                "release_date": "2018-10-12T00:00:00",
                "artist": {
                    "genre": "Rock",
                    "name": "Young the Giant",
                    "headshot": "https://cdn.buttercms.com/jqVWtHf6T6acW8APrh3g"
                },
                "cover_art": "https://cdn.buttercms.com/ThLT87lBSzyCkhivr64l",
                "album_name": "Mirror Master"
            }
        ]
    }
}

This use case demonstrates is how you can use Collections to create tables of data that Reference each other for complex content structures.

Page Facets to Group/Filter By

You can use Collections as Facets (filterable properties) for your Pages. The simpliest example would be to add Categories to your Pages. Let's say you have a recipe website for different cocktails and you want to add categories to better organize these cocktail pages for your customers.

Each cocktail Page has a name, image, and ingredients, like the below example:

Here's what the API JSON response looks like for your cocktail pages. You're going to enhance this by adding a Reference to a Category Collection.

GET https://api.buttercms.com/v2/pages/cocktails/

{
    "data": [
        {

            "fields": {
                "name": "Old Fashioned",
                "image": "https://cdn.buttercms.com/k4UHbZOuRhOMKw3Gys8s",
                "ingredients": "<p>1/2 tsp Sugar<br />3 dashes Angostura bitters<br />1 tsp Water<br />2 oz Bourbon</p>"
            }
        },
        {
            "slug": "martini",
            "fields": {
                "name": "Martini",
                "image": "https://cdn.buttercms.com/UKVn6r1RQSVyKoZIVeHU",
                "ingredients": "<p>2 oz. vodka</p>\n<p>1/2 oz. dry vermouth</p>\n<p>Shake ingredients with ice. Strain into a martini glass. Popular garnishes include a lemon twist and olives.</p>"
             }
        }
    ],
    meta": {
        "count": 2,
        "previous_page": null,
        "next_page": null
    }
}

To add a Category to your cocktail pages, create a new collection. Configure your Collection data structure by adding "Name" and "Slug" properties to it.

Save it with the name "Category".

Now you can add some cocktail categories to it like Martini, Old Fashioned, etc...

You can choose "Category" in the drop-down on the collections dashboard to see all of your categories.

With your Collection in place, go back to your Cocktail Page Type by clicking on the three dots in the corner of any Cocktail page and clicking on "edit schema." Add a new Reference field called "Category" to the Category Collection

Now when editing your cocktail pages, you can now categorize your cocktails.

These categories of course also show up in your API response your cocktails:

GET https://api.buttercms.com/v2/pages/cocktails/

{
    "data": [
        {
            "slug": "old-fashioned",
            "fields": {
                "name": "Old Fashioned",
                "image": "https://cdn.buttercms.com/k4UHbZOuRhOMKw3Gys8s",
                "ingredients": "<p>1/2 tsp Sugar<br />3 dashes Angostura bitters<br />1 tsp Water<br />2 oz Bourbon</p>",
                "category": {
                    "name": "Old Fashioned",
                    "slug": "old-fashioned"
                }
            }
        },
        {
            "slug": "martini",
            "fields": {
                "name": "Martini",
                "image": "https://cdn.buttercms.com/UKVn6r1RQSVyKoZIVeHU",
                "ingredients": "<p>2 oz. vodka</p>\n<p>1/2 oz. dry vermouth</p>\n<p>Shake ingredients with ice. Strain into a martini glass. Popular garnishes include a lemon twist and olives.</p>",
                "category": {
                    "name": "Martini",
                    "slug": "martini"
                }
             }
        }
    ],
    meta": {
        "count": 2,
        "previous_page": null,
        "next_page": null
    }
}

Naturally, now that your pages have categories, you'll want to filter your pages by category. To do this just add fields.category.slug=martini to your API query.

GET https://api.buttercms.com/v2/pages/cocktails/?&fields.category.slug=martini

{
    "data": [
        {
            "slug": "martini",
            "fields": {
                "name": "Martini",
                "image": "https://cdn.buttercms.com/UKVn6r1RQSVyKoZIVeHU",
                "ingredients": "<p>2 oz. vodka</p>\n<p>1/2 oz. dry vermouth</p>\n<p>Shake ingredients with ice. Strain into a martini glass. Popular garnishes include a lemon twist and olives.</p>",
                "category": {
                    "name": "Martini",
                    "slug": "martini"
                }
             }
        }
    ],
    meta": {
        "count": 1,
        "previous_page": null,
        "next_page": null
    }
}

To take this example further, let's say you wanted multiple Facets to organize your cocktails by. You could set up multiple Collections such as:

• Drink Types: Cider, Colada, Cosmo, ...
• Spirits: Bourbon, Whiskey, Gin
• Color: Brown, Yellow, Orange

Then you would add a corresponding Reference field to link each Collection to your cocktail Pages.

This use case demonstrates is how you can use Collections to add filterable Facets to your Pages.

Reusable Promotional Page Content

There are many use cases for Collections. Another is using Collections to store reusable promotional content that can be Referenced by multiple pages. A common example is customer testimonials. You can store all of your testimonials in a Collection, then Reference those testimonials from your Pages. Here's how you'd do that:

First let's assume your marketing site has some features Pages, each focusing on a particular feature of your product or service.

Here's what the API JSON response looks like for your feature page. You're going to enhance this by adding a Reference to a Testimonials Collection.

GET https://api.buttercms.com/v2/pages/*/full-cms-feature-page

{
    "data": {
        "slug": "full-cms-feature-page",
        "name": "Full CMS Feature Page",
        "published": "2021-08-31T14:36:13.120532Z",
        "updated": "2021-08-31T14:36:13.120532Z",
        page_type": null,
        "fields": {
            "headline": "Powerful CMS. Zero headache.",
            "hero_image": "https://cdn.buttercms.com/RB2R32WbSxqcanOXiHYA",
            "benefits": [
                {
                    "benefit": "SEO Landing Pages"
                },
                {
                    "benefit": "Customer Case Studies"
                },
                {
                    "benefit": "Company News & Updates"
                }
            ]
        }
    }
}

Create a Collection for testimonials, each having the name of the person, their quote, a headshot, and their title + company.

Create some testimonials.

Here's your collections panel, filtered by "Testimonials."

Then add a Reference field from your feature Pages to your Testimonials Collection by clicking on the three dots in the upper right hand corner of any feature page and editing the page schema.

Now you can easily add multiple testimonials to display on your marketing Pages

The API JSON response for your feature page now includes the testimonials you just linked.

GET https://api.buttercms.com/v2/pages/*/full-cms-feature-page

{
    "data": {
        "slug": "full-cms-feature-page",
        "fields": {
            "headline": "Powerful CMS. Zero headache.",
            "hero_image": "https://cdn.buttercms.com/RB2R32WbSxqcanOXiHYA",
            "benefits": [
                {
                    "benefit": "SEO Landing Pages"
                },
                {
                    "benefit": "Customer Case Studies"
                },
                {
                    "benefit": "Company News & Updates"
                }
            ],
            "testimonials": [
                {
                    "name": "Maggie Summers",
                    "headshot": "https://cdn.buttercms.com/iAvdwmxmSjKVfpuqPjWJ",
                    "title_company": "Sasquatch",
                    "quote": "After several attempts at implementing an open source CMS into my app, I found Butter. It’s the best!"
                },
                {
                    "name": "Drew Johnson",
                    "headshot": "https://cdn.buttercms.com/q3z0MfVTJWso2JM5IXvg",
                    "title_company": "App Partner",
                    "quote": "Wordpress was too slow and impacting our business. Butter is more performant and a faster alternative. A no brainer."
                },
                {
                    "name": "BEAU O'HARA",
                    "headshot": "https://cdn.buttercms.com/vOWy5G1LRzm60NyRd3P0",
                    "title_company": "Anstar Products",
                    "quote": "I've tried other API-first CMS'. I liked their programs, but I got yours up and running the fastest"
                }
            ]
        }
    }
}

This use case demonstrates is how you can use Collections to store reusable promotional content that can be Referenced by multiple pages.

Introduction

GET https://api.buttercms.com/v2/posts/?auth_token=your_token

Learn how to quickly build a CMS-powered blog with Flutter with great SEO. Use the full feature set of Butter on Android, iOS and more! To get started even quicker, here's a set of sample blog templates you can use.

If you need help after reading this, contact us via email or livechat.

Install SDK

If you haven't already, you'll want to install our SDK to make querying your content from our API into your app even easier. Once you've done that, you're ready to begin setting up your blog.

Display Posts

Too display posts we create a page and use the Butter client for fetching posts. See our API reference for additional options such as filtering by category or author. The response also includes metadata.

Setup the Blog page to list all our posts

We'll setup a page that fetches and displays posts:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class PostsListScreen extends StatefulWidget {
    final int page;

    const PostsListScreen({Key key, this.page}) : super(key: key);

    @override
    _PostsListScreenState createState() => _PostsListScreenState();
}

class _PostsListScreenState extends State {
    Butter butter = Butter("YOUR_API_KEY");

    Map jsonMap;

    @override
    void initState() {
        super.initState();
        butter.post
            .list({"page": widget.page.toString() ?? "1", "page_size": "10"}).then((response) {
                setState(() {
                    // First fetch the json response,then decode into a map
                    jsonMap = json.decode(response.body);
            });
        });
    }

@override
Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
            title: Text("Posts"),
            ),
        body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
    );
}

Widget _buildLoadingScreen() {
    return Center(
        child: CircularProgressIndicator(),
    );
}

Widget _buildBody() {
    List posts = jsonMap["data"];

    return ListView.builder(
        itemBuilder: (context, position) {
            return ListTile(
                title: Text(posts[position]["title"]),
                leading: Image.network(
                    posts[position]["fields"]["customer_logo"],
                width: 40.0,
                height: 40.0,
            ),
            subtitle: Text(posts[position]["author"]["first_name"] +
            " " +
            posts[position]["author"]["last_name"]),
            );
        },
        itemCount: posts.length,
        );
    }
}

Once the posts are fetched, we refresh our page by calling setState. All methods in the Butter package return a Future we can use for getting data or catching errors.

Setup the Blog Post page to list a single post

Here, we fetch a single blog post using the slug of the post.

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class PostDetailScreen extends StatefulWidget {
    final String pageSlug;

    const PostDetailScreen({Key key, this.pageSlug}) : super(key: key);

    @override
    _PostDetailScreenState createState() => _PostDetailScreenState();
}

class _PostDetailScreenState extends State {
    Butter butter = Butter("YOUR_API_KEY");

    Map jsonMap;

    @override
    void initState() {
        super.initState();
        butter.post.retrieve(widget.pageSlug).then((response) {
            setState(() {
                // First fetch the json response,then decode into a map
                jsonMap = json.decode(response.body);
            });
        });
    }

    @override
    Widget build(BuildContext context) {
        return Scaffold(
            appBar: AppBar(
            title: Text("Post Detail"),
            ),
            body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
        );
    }

    Widget _buildLoadingScreen() {
        return Center(
            child: CircularProgressIndicator(),
        );
    }

    Widget _buildBody() {
        Map post = jsonMap["data"];

        return ListView(
            children: [
            Padding(
                padding: const EdgeInsets.all(8.0),
                child: Text(post["seo_title"]),
            ),
            Padding(
                padding: const EdgeInsets.all(8.0),
                child: Image.network(post["featured_image"]),
            ),
            Padding(
                padding: const EdgeInsets.all(8.0),
                child: Text(post["meta_description"]),
            ),
        ],
    );
    }
}

Now our app has a working blog that can be updated easily in the ButterCMS dashboard.

Previewing Posts

Butter is a headless CMS, which means the design, layout, and general look & feel of your blog is controlled by your own application. As you've seen above, we return your blog content as JSON data, which you then inject into your own templates. In other words, your blog templates are just another set of templates in your app and customizing how your blog looks is the same workflow as any other page in your app. A huge benefit to this is that your blog instantly utilizes all of your existing brand CSS styling so it looks great and visually matches the rest of your app.

Because your app controls the design of your blog, Butter utilizes it to generate live previews for your content editors when they want to preview a blog post before they publish it.

Click here to configure your Blog Preview URL

To setup previewing you will need to tell Butter what your Blog's base preview URL is. i.e.:

https://yoursite.com/blog/

Once that's defined, when you preview a blog post, Butter will append the blog post slug to that preview URL and take you to:

https://yoursite.com/blog/blog-post-slug

To provide a great content editing experience, we highly recommend setting your preview URL.

Categories, Tags, and Authors

Use Butter's APIs for categories, tags, and authors to feature and filter content on your blog:

List all categories and get posts by category

Categories allow you to sort your blog posts by characteristics.

Fetching Categories:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class CategoriesListScreen extends StatefulWidget {
 @override
 _CategoriesListScreenState createState() => _CategoriesListScreenState();
}

class _CategoriesListScreenState extends State {
 Butter butter = Butter("YOUR_API_KEY");

 Map jsonMap;

 @override
 void initState() {
   super.initState();
   butter.category.list().then((response) {
     setState(() {
       // First fetch the json response, then decode into a map
       jsonMap = json.decode(response.body);
     });
   });
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text("Categories"),
     ),
     body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
   );
 }

 Widget _buildLoadingScreen() {
   return Center(
     child: CircularProgressIndicator(),
   );
 }

 Widget _buildBody() {
   List categories = jsonMap["data"];

   return ListView.builder(
     itemBuilder: (context, position) {
       return ListTile(
         title: Text(categories[position]["title"]),
         subtitle: Text(categories[position]["slug"]),
       );
     },
     itemCount: categories.length,
   );
 }
}

Fetching tags:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class TagsListScreen extends StatefulWidget {
 @override
 _TagsListScreenState createState() => _TagsListScreenState();
}

class _TagsListScreenState extends State {
 Butter butter = Butter("YOUR_API_KEY");

 Map jsonMap;

 @override
 void initState() {
   super.initState();
   butter.tag.list().then((response) {
     setState(() {
       // First fetch the json response, then decode into a map
       jsonMap = json.decode(response.body);
     });
   });
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text("Tags"),
     ),
     body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
   );
 }

 Widget _buildLoadingScreen() {
   return Center(
     child: CircularProgressIndicator(),
   );
 }

 Widget _buildBody() {
   List tags = jsonMap["data"];

   return ListView.builder(
     itemBuilder: (context, position) {
       return ListTile(
         title: Text(tags[position]["title"]),
         subtitle: Text(tags[position]["slug"]),
       );
     },
     itemCount: tags.length,
   );
 }
}

You can fetch all authors or one author using list and retrieve respectively. You can also retrieve recent posts from an author.

Fetching authors:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:buttercms_dart/buttercms_dart.dart';

class AuthorsListScreen extends StatefulWidget {
 @override
 _AuthorsListScreenState createState() => _AuthorsListScreenState();
}

class _AuthorsListScreenState extends State {
 Butter butter = Butter("YOUR_API_KEY");

 Map jsonMap;

 @override
 void initState() {
   super.initState();
   butter.author.list().then((response) {
     setState(() {
       // First fetch the json response, then decode into a map
       jsonMap = json.decode(response.body);
     });
   });
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text("Authors"),
     ),
     body: jsonMap == null ? _buildLoadingScreen() : _buildBody(),
   );
 }

 Widget _buildLoadingScreen() {
   return Center(
     child: CircularProgressIndicator(),
   );
 }

 Widget _buildBody() {
   List authors = jsonMap["data"];

   return ListView.builder(
     itemBuilder: (context, position) {
       return ListTile(
         title: Text(authors[position]["first_name"] + " " + authors[position]["last_name"]),
         subtitle: Text(authors[position]["email"]),
       );
     },
     itemCount: authors.length,
   );
 }
}

See our API reference for more information about these objects:

• Categories
• Tags
• Authors

RSS, Atom, and Sitemap

Butter generates RSS, Atom, and sitemap XML markup. To use these on your blog, return the generated XML from the Butter API with the proper content type headers.

Setup to create feeds and sitemap

If you want to statically generate these xml files you can use our Webhooks which will POST change notifications to your app.

Setup up a listener webhook on your hosting that will trigger a rebuild or redeploy of your static site when it receives a POST request.

Setup a POST Webhook in the ButterCMS dashboard with the Event "Blog Post Create, Update, or Delete" and paste the listener url into Target URL field.

Comments

Butter doesn't provide an API for comments due to the excellent existing options that integrate easily. Two popular services we recommend are:

• Disqus
• Facebook Comments

Both products are free, include moderation capabilities, and give your audience a familiar commenting experience. They can also provide some additional distribution for your content since users in their networks can see when people comment on your posts. For a minimalist alternative to Disqus, check out RemarkBox or for an open-source option, Isso.

Social Sharing

To maximize sharing of your content, we recommend using a free tool called AddThis.

They provide an attractive and easy to integrate social sharing widget that you can add to your website.

CSS

Butter integrates into your front-end so you have complete control over the design of your blog. Use the following CSS as boilerplate for post content styling.

.post-container {
  h1, h2, h3, h4, h5 {
    font-weight: 600;
    margin-bottom: 1em;
    margin-top: 1.5em;
  }

  ul, ol {
    margin-bottom: 1.25em;

    li {
      margin-bottom: 0.25em;
    }
  }

  p {
    font-family: Georgia, Cambria, "Times New Roman", Times, serif;
    font-size: 1.25em;
    line-height: 1.58;
    margin-bottom: 1.25em;
    font-weight: 400;
    letter-spacing: -.003em;
  }

  /* Responsive default image width */
  img {
    max-width: 100%;
    height: auto;
  }

  /* Responsive floating */
  @media only screen and (min-width: 720px)  {
    .butter-float-left {
      float: left;
      margin: 0px 10px 10px 0px;
    }

    .butter-float-right {
      float: right;
      margin: 0px 0px 10px 10px;
    }
  }

  /* Image caption */

Headless CMS

ButterCMS is a headless CMS that lets you manage content using our dashboard and integrate it into your tech stack of choice with our content APIs. You can use ButterCMS for new projects as well as add it to existing codebases.

If you're familiar with Wordpress, see how ButterCMS compares to WordPress.

ButterCMS provides a user-friendly UI for managing marketing sites, blogging, and custom content scenarios. We can be used for SEO landing pages, customer case studies, company news & updates, events + webinar pages, education center, location pages, knowledgebases, and more.

We are different from a traditional CMS like Drupal or Wordpress in that we're not a large piece of software you need to download, host, customize, and maintain. Instead we provide easy to consume, performant content API's that you add to your application.

For example, if you wanted to enable a non-technical person to be able to add customer case study pages to your marketing site, you might create a Case Study Page Type to represent these pages. The non-technical person would be able to manage these pages from our dashboard and the JSON API output would look something like this:

{  
  "data": {
    "slug": "acme-co",
    "name": "Acme Co",
    "published": "2021-08-23T14:28:21.077112Z",
    "updated": "2021-08-23T14:28:21.077112Z",
    "page_type": "case_study",
    "fields": {
      "seo_title": "Acme Co Loves Butter CMS",
      "seo_description": "Acme Co saved 200% on Anvil costs with ButterCMS",
      "headline": "Acme Co saved 200% on Anvil costs with ButterCMS",
      "facebook_open_graph_title": "Acme Co Customer Case Study",
      "customer_logo": "https://cdn.buttercms.com/66oMGYOuSP2V0bsK6gKd",
      "testimonial": "<p>We've been able to make anvils faster than ever before!<em>--Chief Anvil Maker Anvil</em></p>
      <p><img src="https://cdn.buttercms.com/queOG6fITpiJAUc7GV30\" alt="" /></p>"""
    }
  }
}

Use Postman to experiment

Postman is a great tool for experimenting with our API. We wrote a post about it here. Once you've installed Postman, click this button to quickly add our end point Collection to your Postman.

Write API

We have a Write / POST API that allows you to programmatically create content. This can enable many powerful use cases and allow you to scale your content faster than ever.

Refer to our Write API Documentation to learn more.

Our Write API is available in our Enterprise plan and you will need to use a write-enabled token which is provided on request. Just contact us via email or livechat to get yours.

Webhooks

Webhooks are a powerful feature that allow you to notify your internal systems whenever content in ButterCMS has changed. You can learn more about Webhooks in this blog post.

Image Transformation

ButterCMS has integrated with a rich image transformation API called Filestack. This allows you to modify your uploaded images in dozens of ways. Everything from resizing, cropping, effects, filters, applying watermarks and more. Check out Filestack full documentation for more detail.

After you upload an image to ButterCMS, it's stored on our CDN. To create a thumbnail, here's an example:

Original URL = https://cdn.buttercms.com/zjypya5tRny63LqhHQrv

Thumbnail URL = https://cdn.buttercms.com/resize=width:200,height:200/zjypya5tRny63LqhHQrv

Resizing is just one of the many different transformations you can do to your images. Refer to the Filestack docs for full details.

Localization

ButterCMS has full support for localization of your content. Locale names and keys are completely customizable and there's no limit to the number of locales you can have. View our API Reference to learn how to query by locale.

Admins can ensure your global team of marketers and translators safely work side-by-side by setting permissions for just their local markets.

Roles and Permissions

In addition to permissions by locale, your ButterCMS account comes with three roles by default, to give your team maximum control over what your users can do:

• Admin - can do everything on an account. You'll want to use this for your developers as they deal with the content configuration that is used within your project's code.
• Publisher - can edit, publish and delete content, but cannot manage users or configure content schemas.
• Author - can create and edit draft content (Blog Posts, Pages, Collections) but cannot publish content live to your site.

Custom built roles are available in our Enterprise plan. Chat with us to discuss Enterprise options.

Manage Multiple Environments

ButterCMS Multisite allows you to manage multiple websites and multiple environments from one place. You can get an admin level view and quickly switch between your ButterCMS instances.

Each site has it's own unique API token which allows for clean separation and easy querying of your content.

From the Environment dashboard you can quickly switch between your different ButterCMS environments. In the example below, Elon is currently logged into Production and can switch into Staging, Dev, or QA in one-click

Multiple Environments are available in our Enterprise plan. Just contact us via email or livechat to get yours.

Multi-Environment Workflow

Preview content before it goes live

To preview draft content before it goes live on your production site, you'll want to set up your own preview site (i.e. preview.yoursite.com or staging.yoursite.com).

Both your preview and production site will connect to your ButterCMS Production environment, but your preview site will always pass preview=1 as a parameter when fetching content from our API:

Using preview=1 will cause the draft version of content to be returned when viewing your preview site. Your marketers can then preview their draft content safely before it appears on your production site.

Make your content editors happy with this seamless workflow

Setting things up in this way is an optimal workflow for your marketers and prevents them from having to worry about physicaly copy/migrating content across your ButterCMS environments. They do all of their work from the same ButterCMS environment.

To publish new content, their workflow is simple and efficient. They can Save Draft (1), Preview (2), and Publish (3) all from the same screen:

1. Save Draft - create a draft version of content that only appears in your preview site, not production
2. Preview - content editors see this draft rendered on your preview site
3. Publish (instantly or scheduled): publish the draft content so it now appears on your production site

Don't use environments for your daily content publishing workflow

If you've used other CMS', you may be used to a workflow where to preview content in a staging site, you put content in a staging CMS environment/database. Then to publish it, you physically copy it over into a production CMS environment/database (either by copying pasting, writing a migration script, building a content sync tool, etc). In a traditional CMS, this makes sense because that's the only way to preview draft content without it first appearing on a production site.

With Butter, that's not the case and you can enable this streamlined workflow your content managers will love.

Use environments for safely iterating on schema changes

A quick note on schema versus content in ButterCMS environments. Schema (Page Types and Collections) in Butter is akin to a schema for a database. They are distinct from the content (data in a database). We recommend using ButterCMS environments for iterating on schema changes safely without worrying about impacting your production environment. For example, testing out launching a new PageType or Collection or making changes to an existing one. Since this impacts the structure of the JSON from our API, you will want to test this in coordination with code changes in your application to display this new content. You can do this safely via a ButterCMS Staging/Dev/etc environments and migrate across environments using our Schema Migration feature.

Schema Migrations

Using multiple environments is a development best practice for creating new content experiences. Working in a non-production environment helps separate experimental changes so you can safely work without accidentally impacting your production application.

ButterCMS Migrations make migrating configuration data across your environments dead simple. Simply create a Migration from a test environment that specifies what you want to migrate and to which environment. For example, let's say we are working on creating a new FAQ section to our site, so we've developed a FAQ Page Type in our Dev environment. Now we are ready to move it to our Staging environment, simply create a Migration:

Configuration versus content

A quick note on migrating configuration data versus content across ButterCMS environments. Configuration data (Page Types and Collections) in Butter is akin to a schema for a database. They are distinct from the content (data in a database). We recommend using ButterCMS environments for Migrating schema only. For example, testing out launching a new PageType or Collection or making changes to an existing one. Since this impacts the structure of the JSON from our API, you will want to test this in coordination with code changes in your application to display this new content. You can do this safely via ButterCMS environments and migrate across environments using our schema Migration feature.

How to handle References

ButterCMS has a powerful feature called References which allows you to create relationships between your content types. In database terminology, this is like a foreign key from one table to another. Here's how to handle this when migrating:

• PageTypeA has Reference to PageTypeB
• Migrate PageTypeB first
• Then migrate PageTypeA

Manage Multiple Websites

Being able to manage multiple environments is great for a large project but what about massive projects where you need to manage multiple sites AND multiple environments? For instance if you're an Enterprise with several sub-branded websites that you want to be able to manage, this allows you to do that. Continuing from the example above, let's say Elon wanted to expand using Butter beyond just Tesla to include SpaceX and The Boring Company as well.

Our dashboard easily scales to meet this need. Now when Elon visits the multisite dashboard, he will see this:

Multiple Websites and Environments are available in our Enterprise plan. Just contact us via email or livechat to get yours.
