Setup Strapi 5 Headless CMS

We are going to start by setting up our Strapi 5 project with the following command:

🖐️ Note: make sure that you have created a new directory for your project.

You can find the full documentation for Strapi 5 here.

npx create-strapi-app@latest server

You will be asked to choose if you would like to use Strapi Cloud we will choose to skip for now.

? Please log in or sign up.

❯ Skip 

After that, you will be asked how you would like to set up your project. We will choose the following options:

? Do you want to use the default database (sqlite) ? Yes
? Start with an example structure & data? Yes <-- make sure you say yes 
? Start with Typescript? Yes
? Install dependencies with npm? Yes
? Initialize a git repository? Yes

Once everything is set up and all the dependencies are installed, you can start your Strapi server with the following command:

cd server
npm run develop

You will be greeted with the Admin Create Account screen.

Go ahead and create your first Strapi user. All of this is local so you can use whatever you want.

Once you have created your user, you will be redirected to the Strapi Dashboard screen.

Publish Article Entries

Since we created our app with the example data, you should be able to navigate to your Article collection and see the data that was created for us.

Now, let's make sure that all of the data is published. If not, you can select all items via the checkbox and then click the Publish button.

Enable API Access

Once all your articles are published, we will expose our Strapi API for the Articles Collection. This can be done in Settings -> Users & Permissions plugin -> Roles -> Public -> Article.

You should have find and findOne selected. If not, go ahead and select them.

Test API

Now, if we make a GET request to http://localhost:1337/api/articles, we should see the following data for our articles.

🖐️ Note: that article covers (images) are not returned. This is because the REST API by default does not populate any relations, media fields, components, or dynamic zones.. Learn more about REST API: Population & Field Selection.

So let's get the article covers by using the populate=* parameter: http://localhost:1337/api/articles?populate=*

Nice, now that we have our Strapi 5 server setup, we can start to setup our Next.js application.

Getting Started With Flutter

It is recommended to use the create-next-app, which sets up everything automatically for you.

Prerequisites

Before you proceed, ensure you have the following:

• Flutter SDK (latest version)
• VS Code or whatever code editor you like.
• An environment setup for Flutter. Check out how to install and setup Flutter.

Step 1: Create a New Flutter Project

Run the Flutter create command to create a new Flutter project. We will name the project my_flutter_app.

flutter create my_flutter_app

Step 2: Start Your Flutter Application

Run the command below to start your Flutter app, make sure to CD into your flutter project:

cd my_flutter_app
flutter run

This is what your app should look like:

Step 3: Install HTTP Package

In your project folder terminal, add the HTTP package to communicate with Strapi using the command below:

flutter pub add http

Next, head over to ./lib/main.dart file to continue the next steps.

Step 4: Import Packages and Define Constant

Imports Flutter's Material Design package (flutter/material.dart), HTTP package (http) and Dart's library for encoding and decoding JSON (dart:convert).

Also, define the Strapi API URL

1// Path: `./lib/main.dart`
2
3import 'package:flutter/material.dart';
4import 'package:http/http.dart' as http;
5import 'dart:convert';
6
7const String strapiUrl = 'http://localhost:1337';

Step 5: Create Entry Point - Main Function

Initialize your Flutter app with runApp(MyApp()) and set MyApp as the root widget of your application.

1// ...
2
3void main() {
4  runApp(MyApp());
5}

Step 6: Create Root Widget - MyApp

Set MaterialApp as the main container for your app. And ArticleScreen as the home screen.

1// ...
2
3class MyApp extends StatelessWidget {
4  @override
5  Widget build(BuildContext context) {
6    return MaterialApp(
7      home: ArticleScreen(),
8    );
9  }
10}

Step 7: Create Stateful Widget - ArticleScreen

Create ArticleScreen stateful widget which will manage the state in _ArticleScreenState.

1// ...
2
3class ArticleScreen extends StatefulWidget {
4  @override
5  _ArticleScreenState createState() => _ArticleScreenState();
6}

Step 8: Create State Class - _ArticleScreenState

1// ...
2
3class _ArticleScreenState extends State<ArticleScreen> {
4  List articles = [];
5
6  @override
7  void initState() {
8    super.initState();
9    fetchArticles();
10  }

• Define the _ArticleScreenState class.
• articles list holds fetched articles.
• initState() is called when the widget is created, triggering fetchArticles().

Step 9: Fetch Articles from Strapi

Send a GET request to http://localhost:1337/api/articles?populate=*. If the response is successful (statusCode == 200), decode the JSON and update the articles list.

Use setState() to refresh the UI with new data.

1// ...
2
3Future<void> fetchArticles() async {
4  final response =
5      await http.get(Uri.parse('$strapiUrl/api/articles?populate=*'));
6  if (response.statusCode == 200) {
7    print('Raw API Response: ${jsonEncode(response.body)}');
8    setState(() {
9      articles = jsonDecode(response.body)['data'];
10    });
11  }
12}

Step 10: Scaffold the UI and Display Articles

Use Scaffold to provide a basic app structure with an AppBar and body. Use the ListView.builder to dynamically create a list of articles.

Wrap each article inside a Card for better UI styling. Display the article cover image, title and description inside a Padding widget.

// ...

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Strapi + Flutter')),
      body: ListView.builder(
        itemCount: articles.length,
        itemBuilder: (context, index) {
          var article = articles[index];
          debugPrint(article.toString());
          return Card(
            margin: EdgeInsets.all(10),
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                // if (article['image'] != null)
                Image.network('$strapiUrl${article['cover']['url']}'),
                Padding(
                  padding: EdgeInsets.all(10),
                  child: Column(
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: [
                      Text(
                        article['title'],
                        style: TextStyle(
                            fontSize: 20, fontWeight: FontWeight.bold),
                      ),
                      SizedBox(height: 5),
                      Text(article['description']),
                    ],
                  ),
                ),
              ],
            ),
          );
        },
      ),
    );
  }
