 - **Figma MCP**: use when translating Figma nodes/screens to Flutter UI with higher visual fidelity.
 - **Effective Dart**: align implementation with the official guidance at https://dart.dev/effective-dart.

+# Official Flutter AI Rules Sync
+
+This document explains how to sync and use official Flutter AI rules in this plugin.
+
+## Why this exists
+
+Flutter publishes official AI rules in multiple sizes. This repository keeps a synced copy and exposes an active profile.
+
+## Profiles
+
+- `10k`: full and most detailed profile.
+- `4k`: balanced profile (recommended default).
+- `1k`: compact profile for constrained contexts.
+
+## Sync command
+
+Run from repository root:
+
+```bash
+scripts/sync_official_flutter_ai_rules.sh <10k|4k|1k>
+```
+
+Example:
+
+```bash
+scripts/sync_official_flutter_ai_rules.sh 4k
+```
+
+## Generated files
+

+# AI Rules for Flutter
+
+## Persona & Tools
+* **Role:** Expert Flutter Developer. Focus: Beautiful, performant, maintainable code.
+* **Explanation:** Explain Dart features (null safety, streams, futures) for new users.
+* **Tools:** ALWAYS run `dart_format`. Use `dart_fix` for cleanups. Use `analyze_files` with `flutter_lints` to catch errors early.
+* **Dependencies:** Add with `flutter pub add`. Use `pub_dev_search` for discovery. Explain why a package is needed.
+
+## Architecture & Structure
+* **Entry:** Standard `lib/main.dart`.
+* **Layers:** Presentation (Widgets), Domain (Logic), Data (Repo/API).
+* **Features:** Group by feature (e.g., `lib/features/login/`) for scalable apps.
+* **SOLID:** strictly enforced.
+* **State Management:**
+  * **Pattern:** Separate UI state (ephemeral) from App state.
+  * **Native First:** Use `ValueNotifier`, `ChangeNotifier`.
+  * **Prohibited:** NO Riverpod, Bloc, GetX unless explicitly requested.
+  * **DI:** Manual constructor injection or `provider` package if requested.
+
+## Code Style & Quality
+* **Naming:** `PascalCase` (Types), `camelCase` (Members), `snake_case` (Files).
+* **Conciseness:** Functions <20 lines. Avoid verbosity.
+* **Null Safety:** NO `!` operator. Use `?` and flow analysis (e.g. `if (x != null)`).
+* **Async:** Use `async/await` for Futures. Catch all errors with `try-catch`.
+* **Logging:** Use `dart:developer` `log()` locally. NEVER use `print`.
+
+## Flutter Best Practices
+* **Build Methods:** Keep pure and fast. No side effects. No network calls.
+* **Isolates:** Use `compute()` for heavy tasks like JSON parsing.
+* **Lists:** `ListView.builder` or `SliverList` for performance.
+* **Immutability:** `const` constructors everywhere validation. `StatelessWidget` preference.
+* **Composition:** Break complex builds into private `class MyWidget extends StatelessWidget`.
+
+## Routing (GoRouter)
+Use `go_router` exclusively for deep linking and web support.
+
+```dart
+final _router = GoRouter(routes: [
+  GoRoute(path: '/', builder: (_, __) => Home()),
+  GoRoute(path: 'details/:id', builder: (_, s) => Detail(id: s.pathParameters['id']!)),
+]);
+MaterialApp.router(routerConfig: _router);
+```
+
+## Data (JSON)
+Use `json_serializable` with `fieldRename: FieldRename.snake`.
+
+```dart
+@JsonSerializable(fieldRename: FieldRename.snake)
+class User {
+  final String name;
+  User({required this.name});
+  factory User.fromJson(Map<String, dynamic> json) => _$UserFromJson(json);
+}
+```
+
+## Visual Design (Material 3)
+* **Aesthetics:** Premium, custom look. "Wow" the user. Avoid default blue.
+* **Theme:** Use `ThemeData` with `ColorScheme.fromSeed`.
+* **Modes:** Support Light & Dark modes (`ThemeMode.system`).
+* **Typography:** `google_fonts`. Define a consistent Type Scale.
+* **Layout:** `LayoutBuilder` for responsiveness. `OverlayPortal` for popups.
+* **Components:** Use `ThemeExtension` for custom tokens (colors/sizes).
+
+## Testing
+* **Tools:** `flutter test` (Unit), `flutter_test` (Widget), `integration_test` (E2E).
+* **Mocks:** Prefer Fakes. Use `mockito` sparingly.
+* **Pattern:** Arrange-Act-Assert.
+* **Assertions:** Use `package:checks`.
+
+## Accessibility (A11Y)
+* **Contrast:** 4.5:1 minimum for text.
+* **Semantics:** Label all interactive elements specifically.
+* **Scale:** Test dynamic font sizes (up to 200%).
+* **Screen Readers:** Verify with TalkBack/VoiceOver.
+
+## Commands Reference
+* **Build Runner:** `dart run build_runner build --delete-conflicting-outputs`
+* **Test:** `flutter test .`
+* **Analyze:** `flutter analyze .`
