## 3. Create a Flutter app

Create a Flutter app using the `flutter create` command.

```bash
flutter create my_app
```

## 4. Set up AI tooling (optional)

<$Partial path="quickstart_ai_tooling.mdx" />

## 5. Install the Supabase client library

The fastest way to get started is to use the [`supabase_flutter`](https://pub.dev/packages/supabase_flutter) client library which provides a convenient interface for working with Supabase from a Flutter app.

Open the `pubspec.yaml` file inside your Flutter app and add `supabase_flutter` as a dependency.

```yaml name=pubspec.yaml
supabase_flutter: ^2.0.0
```

## 6. Initialize the Supabase client

Open `lib/main.dart` and edit the main function to initialize Supabase using your project URL and publishable key, which you can get from the helper below, or [from the project **Connect** panel](/dashboard/project/_?showConnect=true&framework=flutter&connectTab=mobiles):

<Button variant="primary" asChild>
  <a href="/dashboard/project/_?showConnect=true&connectTab=mobiles&framework=flutter">
    Open Connect panel
  </a>
</Button>

```dart name=lib/main.dart
import 'package:supabase_flutter/supabase_flutter.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Supabase.initialize(
    url: 'YOUR_SUPABASE_URL',
    publishableKey: 'YOUR_SUPABASE_PUBLISHABLE_KEY',
  );
  runApp(MyApp());
}
```

<$Partial path="api_settings.mdx" variables={{ "framework": "flutter", "tab": "mobiles" }} />

<$Partial path="quickstart_mobile_env_note.mdx" />

## 7. Query data from the app

Use a `FutureBuilder` to fetch the data when the home page loads and display the query result in a `ListView`.

Replace the default `MyApp` and `MyHomePage` classes with the following code.

```dart name=lib/main.dart
class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: 'Instruments',
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  final _future = Supabase.instance.client
      .from('instruments')
      .select();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FutureBuilder(
        future: _future,
        builder: (context, snapshot) {
          if (snapshot.hasError) {
            return Center(child: Text('Error loading instruments: ${snapshot.error}'));
          }
          if (!snapshot.hasData) {
            return const Center(child: CircularProgressIndicator());
          }
          final instruments = snapshot.data!;
          return ListView.builder(
            itemCount: instruments.length,
            itemBuilder: ((context, index) {
              final instrument = instruments[index];
              return ListTile(
                title: Text(instrument['name']),
              );
            }),
          );
        },
      ),
    );
  }
}
```

## 8. Start the app

Run your app on a platform of your choosing! By default an app should launch in your web browser.

Note that `supabase_flutter` is compatible with web, iOS, Android, macOS, and Windows apps.
Running the app on macOS requires additional configuration to [set the entitlements](https://docs.flutter.dev/development/platform-integration/macos/building#setting-up-entitlements).

```bash
flutter run
```

## 9. Setup deep links (optional)

Many sign in methods require deep links to redirect the user back to your app after authentication. Read more about setting deep links up for all platforms (including web) in the [Flutter Mobile Guide](/docs/guides/getting-started/tutorials/with-flutter#setup-deep-links).

### Android

In production, your Android app needs explicit permission to use the internet connection on the user's device which is required to communicate with Supabase APIs.
To do this, add the following line to the `android/app/src/main/AndroidManifest.xml` file.

```xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <!-- Required to fetch data from the internet. -->
  <uses-permission android:name="android.permission.INTERNET" />
  <!-- ... -->
</manifest>
```
