🎵 SwingMusic Mobile Development Plan

📱 Current Status

✅ Completed

Desktop App: Cross-platform (Linux, Windows, macOS) - Tauri + Rust
Android App: Native Kotlin implementation
Backend: Python REST API server
Web Client: Vue.js frontend
CI/CD: Unified release system with semantic versioning
Fully convert the current android app app to the unified flutter app - but keep the original folder as a reference and backup dont remove it or edit anything in it, only create in the new one

🎯 Target

iOS App: Flutter cross-platform implementation
Unified Mobile: Single codebase for iOS + Android

🚀 Flutter Implementation Plan

Phase 1: Project Setup & Foundation (Week 1-2)

🔧 Technical Architecture

🏗️ State Management

Provider Pattern (Recommended for simplicity)

// Audio provider for global state
class AudioProvider extends ChangeNotifier {
  AudioPlayer _player;
  TrackModel? _currentTrack;
  bool _isPlaying = false;
  
  // Audio controls, state management
}

// Library provider for data
class LibraryProvider extends ChangeNotifier {
  List<TrackModel> _tracks;
  List<AlbumModel> _albums;
  List<ArtistModel> _artists;
  
  // Library management
}

🌐 API Integration

// Retrofit for type-safe API
@RestApi(baseUrl: 'https://your-api.com')
abstract class MusicApiService {
  @GET('/tracks')
  Future<List<TrackModel>> getTracks();
  
  @GET('/albums')
  Future<List<AlbumModel>> getAlbums();
  
  @POST('/playlists')
  Future<PlaylistModel> createPlaylist(@Body() PlaylistModel playlist);
}

💾 Local Storage

// Hive for local caching
class TrackAdapter extends TypeAdapter<TrackModel> {
  @override
  TrackModel read(BinaryReader reader) {
    // Deserialization
  }
  
  @override
  void write(BinaryWriter writer, TrackModel obj) {
    // Serialization
  }
}

📋 CI/CD Integration

🔄 Build Pipeline Updates

# Add to unified-release.yml
