+
+## 🏗️ Architecture
+
+Rythmify follows a **Clean Architecture** approach, ensuring the codebase is scalable, maintainable, and testable. The project is organized by **features**:
+
+```text
+lib/
+├── config/           # Application-wide configurations (Theme, Constants)
+├── core/             # Shared logic, utilities, and common UI components
+│   ├── data/         # Common data sources & repositories
+│   ├── domain/       # Shared entities & use cases
+│   ├── presentation/ # Shared widgets
+│   ├── routing/      # Navigation logic (GoRouter)
+│   └── services/     # Third-party service integrations
+└── features/         # Feature-specific modules
+    ├── authentication/
+    ├── player/
+    ├── track_upload/
+    ├── track/
+    ├── feed/
+    ├── comments/
+    ├── messaging/
+    ├── notifications/
+    ├── profile/
+    ├── playlist/
+    ├── library/
+    ├── search/
+    ├── settings/
+    └── premium/
+```
+
+Each feature module is further divided into `data`, `domain`, and `presentation` layers to maintain strict separation of concerns.
+
+---
+
+## 🚀 Getting Started
+
+### Prerequisites
+- [Flutter SDK](https://docs.flutter.dev/get-started/install) (3.11.1+)
+- [Dart SDK](https://dart.dev/get-started)
+- [Docker](https://www.docker.com/) (Optional, for local mock backend)
+
+### Installation
+
+1. **Clone the repository:**
+   ```bash
+   git clone https://github.com/your-username/rythmify.git
+   cd rythmify
+   ```
+
+2. **Install dependencies:**
+   ```bash
+   flutter pub get
+   ```
+
+3. **(Optional) Run local mock API:**
+   Rythmify uses a local `json-server` for development.
+   ```bash
+   docker-compose up -d
+   ```
+
+4. **Run the application:**
+   ```bash
+   flutter run
+   ```

+// lib/features/playlist/data/datasources/playlist_remote_datasource.dart
+/// PURPOSE:
+/// Centralized API service responsible for all playlist-related backend
+/// communication using Dio. This includes fetching playlists, tracks,
+/// stations, mixes, recommendations, and handling engagement actions.
+///
+/// RESPONSIBILITIES:
+/// - CRUD operations for playlists (create, read, update, delete)
+/// - Fetch playlist details and tracks
+/// - Handle likes/unlikes for playlists, mixes, stations, radios
+/// - Fetch discovery content (mixes, stations, recommendations)
+/// - Map raw API responses into domain entities
+/// - Normalize inconsistent backend responses
+///
+/// KEY ENDPOINT GROUPS:
+/// - /playlists → core playlist operations
+/// - /playlists/:id/tracks → playlist tracks
+/// - /home/* → mixes, stations, discovery feeds
+/// - /tracks/* → radio, related, and single track data
+/// - /users/me/* → saved stations and user-specific data
+///
+/// IMPORTANT BEHAVIOR:
+/// - Uses defensive parsing due to inconsistent backend shapes
+/// - Cross-checks LocalSavedStore for missing backend flags
+/// - Handles multiple content types (playlist, mix, station, radio)
+/// - Mix/station mapping uses relaxed validation (no filtering)
+/// - Playlist mapping enforces strict domain consistency
+///
+/// DESIGN NOTES:
+/// - Pure data layer (no UI logic)
+/// - Strong separation between mapping and networking
+/// - Extensive logging for debugging backend inconsistencies
+/// - Fail-safe parsing for partial or malformed responses
+///
+/// ERROR HANDLING:
+/// - DioException is caught per endpoint
+/// - Fallback empty lists returned for non-critical feeds
+/// - Critical operations rethrow for higher-level handling

+// Lightweight track model used inside playlist UI.
+// Carries only what the playlist screens need to render a row.
+// [fromTrack] converts a full [Track] entity into this model.
+// [trackId] holds a reference back to the original [Track] so the

+
+/// This file defines the lightweight PlaylistTrack model used inside playlist
+/// screens and playlist UI.
+///
+/// Purpose:
+/// - Stores only the track information needed for playlist rendering
+/// - Provides helper formatting methods
+/// - Supports converting full Track entities into PlaylistTrack objects
+///
+/// Main Components:
+/// - PlaylistTrack:
+///     Lightweight playlist track model.
+///
+/// Features:
+/// - Formatted duration helper
+/// - Formatted play count helper
+/// - Immutable updates using copyWith()
+/// - Factory constructor for Track conversion
+///
+/// Methods:
+/// - formattedDuration:
+///     Returns track duration as mm:ss.
+///
+/// - formattedPlayCount:
+///     Returns formatted play count string.
+///
+/// - copyWith():
+///     Creates a modified copy of the track.
+///
+/// - PlaylistTrack.fromTrack():
+///     Converts a Track entity into a PlaylistTrack.
+///
+/// Dependencies:
+/// - Track entity

+// lib/features/playlist/presentation/providers/playlist_provider.dart
+/// PURPOSE:
+/// This file contains all Riverpod Notifiers responsible for managing playlist
+/// state across the app, including playlist lists, playlist details, and
+/// playlist-related actions (create, update, delete, copy, and conversions).
+///
+/// RESPONSIBILITIES:
+/// - Manage playlist list state (owned, liked, albums)
+/// - Manage playlist detail state (tracks, suggestions, likes)
+/// - Handle playlist lifecycle actions (create, update, delete, copy)
+/// - Convert playlists between types (playlist / album / station)
+/// - Coordinate with remote datasource + local cache layer
+/// - Maintain optimistic UI updates where needed
+///
+/// KEY COMPONENTS:
+/// - PlaylistListNotifier → handles library playlists (owned/liked/albums)
+/// - PlaylistDetailNotifier → handles single playlist screen state
+/// - PlaylistMockData → local cache for offline/instant updates
+/// - PlaylistRemoteDatasource → API layer (via Dio)
+///
+/// IMPORTANT BEHAVIOR:
+/// - "suggestions" are ONLY loaded manually via owner-triggered flow
+/// - Station / Mix / TrackRadio types have special fetching logic
+/// - Copy playlist adapts behavior based on source type
+/// - Cache is always synced after backend mutations
+///
+/// DESIGN NOTES:
+/// - Uses optimistic updates for better UX
+/// - Separates list vs detail state for performance
+/// - Avoids unnecessary network calls unless explicitly triggered

+// lib/features/playlist/presentation/providers/saved_content_provider.dart
+//
+// FIX: After liking a mix or track radio, we call loadLikedPlaylists() so
+// the item appears in Library → Playlists → Liked tab.
+//
+// WHY: The backend creates a real playlist row on like. That row is returned
+// by GET /playlists?mine=true&filter=liked. The library "Liked" tab calls
+// loadLikedPlaylists() when selected — but if the user is already on that
+// tab, the state is stale. By awaiting the reload inside toggle(), the state
+// updates immediately without user needing to switch tabs.
+
+/// PURPOSE:
+/// Manages user "saved" interactions including mixes, track radios, and stations.
+/// This layer ensures UI stays synced with backend-like side effects such as
+/// playlist creation triggered by likes.
+///
+/// RESPONSIBILITIES:
+/// - Toggle saved state for mixes, stations, and track radios
+/// - Maintain optimistic UI updates with rollback on failure
+/// - Persist local saved state via LocalSavedStore
+/// - Trigger playlist refresh when backend creates new liked entities
+/// - Sync library "Liked" playlists after mutations
+///
+/// KEY BEHAVIOR:
+/// - Liking a mix → creates backend playlist → triggers reloadLikedPlaylists()
+/// - Liking a track radio → creates playlist row → triggers reload
+/// - Stations are synced via /users/me/stations endpoint
+///
+/// IMPORTANT DESIGN DECISIONS:
+/// - Uses optimistic state updates for instant UI feedback
+/// - Always re-syncs playlist library after successful like actions
+/// - Separates mix / radio / station logic for clarity
+///
+/// DATA SOURCES:
+/// - PlaylistRemoteDatasource (API calls)
+/// - LocalSavedStore (local persistence cache)
+/// - playlistListProvider (library refresh coordination)
+///
+/// FAILURE HANDLING:
+/// - Any API failure triggers rollback to previous state
+/// - UI never blocks; operations are async-safe

+// lib/features/playlist/presentation/screens/mix_detail_screen.dart
+
+/// Displays the full details of a generated music mix including:
+/// - Mix metadata and cover image
+/// - Track list with playback support
+/// - Save/unsave functionality
+/// - Shuffle and play controls
+/// - Bottom sheet actions
+///
+/// This screen listens reactively to saved mix providers so the UI updates
+/// instantly when the mix is liked or unliked from anywhere in the app.
+///
+/// Main responsibilities:
+/// - Load mix tracks using mixTracksProvider
+/// - Build playback queue using queueStateProvider
+/// - Toggle saved state using savedMixesProvider
+/// - Display responsive track list and mix information
+///
+/// Widgets included:
+/// - MixDetailScreen          → Async data loader wrapper
+/// - _MixDetailBody           → Main screen UI and interactions
+/// - _Cover                   → Reusable mix artwork widget
+///
+/// Queue context:
+/// Playback is started using QueueSource.mix to preserve
+/// player navigation and playback history behavior.

+// lib/features/playlist/presentation/screens/playlist_detail_screen.dart
+/// Displays the complete details of a playlist, album, station,
+/// or generated collection.
+///
+/// Features:
+/// - Playlist metadata and artwork
+/// - Track listing with playback support
+/// - Shuffle and play-all functionality
+/// - Like/unlike playlist support
+/// - Playlist copy functionality
+/// - Playlist management options
+/// - Owner-only track suggestions
+///
+/// This screen supports multiple playlist types:
+/// - Regular playlists
+/// - Albums
+/// - Artist stations
+/// - Generated mixes
+/// - Track radios
+///
+/// Main responsibilities:
+/// - Initialize playlist data using playlistDetailProvider
+/// - Fetch full track details before playback
+/// - Build queue playback context dynamically
+/// - Display suggestions for owned playlists
+/// - Allow playlist duplication for non-owners
+/// - Manage playlist actions and navigation
+///
+/// Widgets included:
+/// - PlaylistDetailScreen     → Main detail screen

+/// - _CopyPlaylistSheet       → Playlist duplication modal
+/// - _CoverImage              → Playlist artwork widget
+///
+/// Playback behavior:
+/// Tracks are converted into full Track entities before
+/// queue playback to ensure complete metadata is available.
+///
+/// Queue sources are mapped dynamically based on PlaylistType.

+// lib/features/playlist/presentation/screens/related_tracks_screen.dart
+/// Displays either:
+/// - Related tracks based on a specific track
+/// - Artist station tracks based on an artist
+///
+/// Features:
+/// - Dynamic track loading
+/// - Full playback support
+/// - Save/unsave stations and track radios
+/// - Shuffle playback
+/// - Bottom sheet actions
+/// - Reactive saved-state updates
+///
+/// This screen supports two content modes:
+/// - RelatedTracksSource.track
+/// - RelatedTracksSource.station
+///
+/// Main responsibilities:
+/// - Load related or station tracks using Riverpod providers
+/// - Convert PlaylistTrack models into playable Track entities
+/// - Build queue playback using queueStateProvider
+/// - Toggle saved stations and saved radios
+/// - Display track metadata and playback controls
+///
+/// State management:
+/// Saved state is derived directly from providers instead of
+/// local cache storage to ensure UI consistency across the app.
+///
+/// Widgets included:
+/// - RelatedTracksScreen      → Async loader wrapper
+/// - _Body                    → Main screen implementation
+/// - _Cover                   → Artwork/placeholder widget
+///
+/// Queue context:
+/// Playback uses QueueSource.station to maintain
+/// proper queue behavior for recommendation-based playback.

+///
+/// It acts as the data layer between the domain layer and the backend
+/// subscription service, using Dio for HTTP communication.
+///
+/// Responsibilities:
+/// - Fetch available subscription plans
+/// - Retrieve the current user's subscription
+/// - Start a checkout session for a selected plan
+/// - Confirm mock payments (used for testing or sandbox flows)
+/// - Cancel an active subscription
+/// - Retrieve pending transactions for checkout flow recovery
+///
+/// API Endpoints Used:
+/// - GET    /subscriptions/plans
+/// - GET    /subscriptions/me
+/// - POST   /subscriptions/checkout
+/// - POST   /subscriptions/mock-confirm/{transaction_id}
+/// - POST   /subscriptions/cancel
+/// - GET    /subscriptions/transactions
+///
+/// Authentication:
+/// Most endpoints require a Bearer token, which is handled automatically

+///
+/// Notes:
+/// - All JSON parsing is delegated to domain entities.

+/// consistent upgrade prompt across the entire app.
+///
+/// Backend Contract:
+/// - HTTP 403 with:
+///   { "error": { "code": "SUBSCRIPTION_LIMIT_REACHED" } }
+///
+/// Responsibilities:
+/// - Detect subscription limit errors from DioException
+/// - Show upgrade bottom sheet when limit is reached
+/// - Route user to upgrade screen when needed
+/// - Provide a single reusable error handler for all features
+///
+/// Usage Pattern:
+/// Call inside any onError block:
+///
+///   PremiumGate.handleError(context, error);
+///
+/// Behavior:
+/// - Returns true → handled as subscription error (UI shown)
+/// - Returns false → not subscription-related, handle normally
+///
+/// UI Component:
+/// - Displays a bottom sheet explaining the limit
+/// - Shows benefits of premium subscription
+/// - Navigates to /upgrade route when user taps "See plans"
+///
+/// Notes:
+/// - This class does NOT perform API calls
+/// - It is strictly a UI + error interpretation layer
+/// - Keeps feature modules free from duplicated subscription logic
+
+// ─────────────────────────────────────────────────────────────────────────────
+// PREMIUM GATE
+//
+// The backend already enforces limits and returns:
+//   HTTP 403 + body: { "error": { "code": "SUBSCRIPTION_LIMIT_REACHED" } }
+//
+// All you do in any feature is call:
+//   PremiumGate.handleError(context, error);
+//
+// inside your existing onError callback. If the error is a subscription limit,
+// it shows the upgrade prompt. Otherwise it returns false and you show your
+// normal error message.

+/// Shows active premium subscription and handles cancellation.
+///
+/// Responsibilities:
+/// - Displays active subscription status
+/// - Shows countdown timer for current session
+/// - Handles subscription cancellation
+/// - Shows premium benefits list
+///
+/// Behavior:
+/// - 5-minute session timer updates every second
+/// - Auto-renews session if not canceled
+/// - After cancel: subscription stays active until session ends
+///
+/// Actions:
+/// - Cancel subscription → disables auto-renew via backend
+/// - Resubscribe → navigates to upgrade flow
+///
+/// Notes:
+/// - Uses simulated session timer for UX purposes
+/// - endDate is optional backend data

+  # This section identifies this Flutter project as a plugin project.
+  # The 'pluginClass' specifies the class (in Java, Kotlin, Swift, Objective-C, etc.)
+  # which should be registered in the plugin registry. This is required for
+  # using method channels.
+  # The Android 'package' specifies package in which the registered class is.
+  # This is required for using method channels on Android.
+  # The 'ffiPlugin' specifies that native code should be built and bundled.
+  # This is required for using `dart:ffi`.
+  # All these are used by the tooling to maintain consistency when
+  # adding or updating assets for this project.

+  # To add assets to your plugin package, add an assets section, like this:
+  # assets:
+  #   - images/a_dot_burr.jpeg
+  #   - images/a_dot_ham.jpeg
+  #
+  # For details regarding assets in packages, see

+  # An image asset can refer to one or more resolution-specific "variants", see
+  # https://flutter.dev/to/resolution-aware-images
+
+  # To add custom fonts to your plugin package, add a fonts section here,
+  # in this "flutter" section. Each entry in this list should have a
+  # "family" key with the font family name, and a "fonts" key with a
+  # list giving the asset and other descriptors for the font. For
+  # example:
+  # fonts:
+  #   - family: Schyler
