This project show you how to create a simple Spotify look-alike app. The app enables users to play songs using the just_audio AudioPlayer. The playback continues as the app is in background mode via the integration with audio_service library.

This project is developed by maxonflutter / atomsbox.com . Feel free to provide feedback or suggest improvements via GitHub.

• Flutter UI: Two screens with playlists and songs
• Audio Player: Integration of the audio_service and just_audio libraries to create a functioning audio player.
• Database and Storage: Firebase integration to store data and songs

Before you can run the app, you'll have to create a Firebase project and load your assets.

Navigate to your Firebase project:

1. Open Cloud Storage: Build --> Storage
2. Click on Upload Files and select the song assets to upload.

To create new documents in a Firestore collection, your db_client should have the set method.

  Future<String> set({
    required String id,
    required String entity,
    required Map<String, dynamic> data,
  }) async {
    try {
      return await _firestore.collection(entity).doc(id).set(data);
    } catch (err) {
      throw Exception('Error adding document: $err');
    }
  }

To add sample data for the user recommendations, you can use the PlaylistRepository.

Create a method to load the sample data from the UserRecommendation class to a document into Firestore.

Future createUserRecommendations() async {
    dbClient.set(
      entity: 'userRecommendations',
      data: UserRecommendations.sampleUserRecommendations.toJson(),
    );
  }

Call the method from the main function

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  final dbClient = FirestoreDbClient();
  final playlistRepository = PlaylistRepository(dbClient: dbClient);
  playlistRepository.createUserRecommendations();

  runApp(const MyApp());
}

You can repeat the same step to load the Song data, Playlist data, etc.

Open the terminal and run the command:

flutter pub get
flutter run
