+# Copilot Instructions for Flutter Game Template
+
+## Project Overview
+This is a mobile game template built with Flutter showcasing a complete starter game with navigation, audio, state management, and optional integrations (ads, in-app purchases, games services, Firebase Crashlytics). The template is intentionally low-level on state management to avoid complexity while remaining extensible.
+
+## Architecture & Key Components
+
+### Feature-First Organization (`lib/src/`)
+Code is organized by feature, not by layer. Each feature directory is semi-independent:
+- `audio/` - Music and sound effects (via `audioplayers` package)
+- `player_progress/` - Game progress tracking with persistence abstraction
+- `settings/` - User preferences (muted, music, sound, player name)
+- `app_lifecycle/` - Lifecycle event monitoring via `WidgetsBindingObserver`
+- `main_menu/`, `level_selection/`, `play_session/`, `win_game/` - Screen features
+- `ads/`, `games_services/`, `in_app_purchase/` - Optional integrations (disabled by default)
+- `style/` - Palette, responsive layout, custom transitions
+
+### State Management Pattern
+Uses **Provider** with a low-level, intentional approach:
+- **ChangeNotifier** for mutable state (`PlayerProgress`, `SettingsController`, `AudioController`)
+- **ValueNotifier** for simple reactive properties (settings values, lifecycle state)
+- **MultiProvider** setup in `main.dart` with explicit dependency ordering
+- Key insight: `AudioController` depends on `SettingsController` via `ProxyProvider2` for reactive attachment
+- No code generation; manually attach listeners using `attachSettings()` and `attachLifecycleNotifier()` patterns
+
+### Persistence Abstraction
+All persistent data uses dependency-injected interfaces:
+- `PlayerProgressPersistence` (injected in `PlayerProgress`)
+- `SettingsPersistence` (injected in `SettingsController`)
+- Default implementation: `LocalStoragePlayerProgressPersistence`, `LocalStorageSettingsPersistence`
+- This allows easy testing or swapping implementations (e.g., Firebase, cloud sync)
+
+### Navigation
+Uses **GoRouter** (v16.0.0+) with nested route structure in `main.dart`:
+- Routes are statically defined in `MyApp._router`
+- Transitions use custom `buildMyTransition<void>()` helper from `src/style/my_transition.dart`
+- Parameters passed via `state.pathParameters` (e.g., level number in `/play/session/:level`)
+- Extra data passed via `state.extra` and validated with guards (e.g., win screen redirect)
+
+### Audio Integration
+`AudioController` is a facade over `audioplayers` package:
+- Manages a music player + pool of SFX players (configurable polyphony, default 2)
+- Automatically shuffles playlist and handles lifecycle pauses
+- Pauses audio when app goes to background; resumes on foreground
+- Settings-aware: respects muted, musicOn, soundsOn toggles
+- Use `audioController.playSfx(SfxType.buttonTap)` to play sound effects
+
+### Optional Integrations (Commented By Default)
+In `main.dart`, integrations are **commented out and must be explicitly enabled**:
+- **Firebase Crashlytics**: Uncomment imports and initialize block; requires `firebase_options.dart`
+- **Google Mobile Ads**: Uncomment `AdsController` initialization; requires `google_mobile_ads` package
+- **Games Services**: Uncomment `GamesServicesController` initialization
+- **In-App Purchase**: Uncomment `InAppPurchaseController` initialization
+- All integrations use platform guards: `!kIsWeb && (Platform.isIOS || Platform.isAndroid)`
+
+## Development Workflows
+
+### Running the App
+```bash
+# Default (emulator/simulator/physical device)
+flutter run
+
+# Desktop (faster iteration, no emulator needed)
+flutter run -d macOS     # or -d linux / -d windows
+
+# Web (useful for demos)
+flutter run -d web
+```
+
+### Building for Production
+```bash
+# iOS
+flutter build ipa && open build/ios/archive/Runner.xcarchive
+
+# Android
+flutter build appbundle && open build/app/outputs/bundle/release
+
+# Web (requires 'peanut' package)
+flutter pub global run peanut --web-renderer canvaskit --extra-args "--base-href=/repo_name/" && git push origin --set-upstream gh-pages
+```
+
+### Analysis & Linting
+Uses `flutter_lints` with minimal overrides (prefer_const_constructors and prefer_single_quotes disabled for early development). Check with:
+```bash
+flutter analyze
+```
+
+## Code Patterns & Conventions
+
+### Logging
+Uses `package:logging` with dev.log:
+```dart
+static final _log = Logger('ClassName');
+_log.info('message');
+_log.warning('warning');
+```
+
+### Responsive UI
+Custom `ResponsiveScreen` widget in `src/style/responsive_screen.dart` provides `mainAreaProminence` and layout areas. Use for adaptive layouts across mobile/tablet/desktop.
+
+### Snack Bar Feedback
+Custom `showSnackBar()` in `src/style/snack_bar.dart`. Use a global `scaffoldMessengerKey` passed to `MaterialApp.router`.
+
+### Palette & Theme
+Centralized `Palette` provider in `src/style/palette.dart`. Inject via `context.watch<Palette>()`. Avoids hardcoding colors.
+
+### Game Levels
+Game levels defined in `src/level_selection/levels.dart` as a list. Reference by level number in routing.
+
+### Screen State Management
+Screens are typically StatelessWidget that watch providers. Mutable interactions go through provider controllers:
+```dart
+final audioController = context.watch<AudioController>();
+audioController.playSfx(SfxType.buttonTap);
+```
+
+## Dependencies Overview
+- **go_router** (v16.0.0): Navigation and routing
+- **provider** (v6.0.2): State management
+- **audioplayers** (v6.0.0): Audio playback
+- **shared_preferences**: Local persistence (via abstraction)
+- **logging**: Structured logging to dart:developer
+- Optional: firebase_core, firebase_crashlytics, google_mobile_ads, games_services, in_app_purchase
+
+## Critical Notes for Contributors
+1. **Persistence is abstracted**: Always use the persistence interface, not SharedPreferences directly
+2. **Controllers manage their own initialization**: Check `initialize()` methods and async setup requirements
+3. **Lifecycle matters**: Audio and ads controllers must respect app lifecycle state
+4. **Platform-specific code**: Use `kIsWeb` and platform checks (`Platform.isIOS`, etc.) for platform-specific logic
+5. **No code generation**: Template intentionally avoids build_runner for simplicity; can be added if needed
+6. **Settings require explicit toggle**: Integrations are commented out; uncomment and enable explicitly when needed
+7. **Router validation**: Use `redirect` guards on sensitive routes (e.g., win screen requires score extra data)
