  Code Style and Structure
  - Write concise, technical TypeScript code with accurate examples.
  - Use functional and declarative programming patterns; avoid classes.
  - Prefer iteration and modularization over code duplication.
  - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
  - Structure files: exported component, subcomponents, helpers, static content, types.
  
  Naming Conventions
  - Use lowercase with dashes for directories (e.g., components/auth-wizard).
  - Favor named exports for components.
  
  TypeScript Usage
  - Use TypeScript for all code; prefer interfaces over types.
  - Avoid enums; use maps instead.
  - Use functional components with TypeScript interfaces.
  
  Syntax and Formatting
  - Use the "function" keyword for pure functions.
  - Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
  - Use declarative JSX.
  
  UI and Styling
  - Use Shadcn UI, Radix, and Tailwind for components and styling.
  - Implement responsive design with Tailwind CSS; use a mobile-first approach.
  
  Performance Optimization
  - Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
  - Wrap client components in Suspense with fallback.
  - Use dynamic loading for non-critical components.
  - Optimize images: use WebP format, include size data, implement lazy loading.
  
  Key Conventions
  - Use 'nuqs' for URL search parameter state management.
  - Optimize Web Vitals (LCP, CLS, FID).
  - allways add JSDOC to every method and every file for js or ts.
  - Limit 'use client':
    - Favor server components and Next.js SSR.
    - Use only for Web API access in small components.
    - Avoid for data fetching or state management.

Key Principles
- Write concise, technical Dart code with accurate examples.
- Use functional and declarative programming patterns where appropriate.
- Prefer composition over inheritance.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
- Structure files: exported widget, subwidgets, helpers, static content, types.

Dart/Flutter
- Use const constructors for immutable widgets.
- Leverage Freezed for immutable state classes and unions.
- Use arrow syntax for simple functions and methods.
- Prefer expression bodies for one-line getters and setters.
- Use trailing commas for better formatting and diffs.

Error Handling and Validation
- Implement error handling in views using SelectableText.rich instead of SnackBars.
- Display errors in SelectableText.rich with red color for visibility.
- Handle empty states within the displaying screen.
- Use AsyncValue for proper error handling and loading states.

Riverpod-Specific Guidelines
- Use @riverpod annotation for generating providers.
- Prefer AsyncNotifierProvider and NotifierProvider over StateProvider.
- Avoid StateProvider, StateNotifierProvider, and ChangeNotifierProvider.
- Use ref.invalidate() for manually triggering provider updates.
- Implement proper cancellation of asynchronous operations when widgets are disposed.

Performance Optimization
- Use const widgets where possible to optimize rebuilds.
- Implement list view optimizations (e.g., ListView.builder).
- Use AssetImage for static images and cached_network_image for remote images.
- Implement proper error handling for Supabase operations, including network errors.

Key Conventions
1. Use GoRouter or auto_route for navigation and deep linking.
2. Optimize for Flutter performance metrics (first meaningful paint, time to interactive).
3. Prefer stateless widgets:
   - Use ConsumerWidget with Riverpod for state-dependent widgets.
   - Use HookConsumerWidget when combining Riverpod and Flutter Hooks.

UI and Styling
- Use Flutter's built-in widgets and create custom widgets.
- Implement responsive design using LayoutBuilder or MediaQuery.
- Use themes for consistent styling across the app.
- Use Theme.of(context).textTheme.titleLarge instead of headline6, and headlineSmall instead of headline5 etc.

Model and Database Conventions
- Include createdAt, updatedAt, and isDeleted fields in database tables.
- Use @JsonSerializable(fieldRename: FieldRename.snake) for models.
- Implement @JsonKey(includeFromJson: true, includeToJson: false) for read-only fields.

Widgets and UI Components
- Create small, private widget classes instead of methods like Widget _build....
- Implement RefreshIndicator for pull-to-refresh functionality.
- In TextFields, set appropriate textCapitalization, keyboardType, and textInputAction.
- Always include an errorBuilder when using Image.network.

Miscellaneous
- Use log instead of print for debugging.
- Use Flutter Hooks / Riverpod Hooks where appropriate.
- Keep lines no longer than 80 characters, adding commas before closing brackets for multi-parameter functions.
- Use @JsonValue(int) for enums that go to the database.

Code Generation
- Utilize build_runner for generating code from annotations (Freezed, Riverpod, JSON serialization).
- Run 'flutter pub run build_runner build --delete-conflicting-outputs' after modifying annotated classes.

Documentation
- Document complex logic and non-obvious code decisions.
- Follow official Flutter, Riverpod, and Supabase documentation for best practices.

Refer to Flutter, Riverpod, and Supabase documentation for Widgets, State Management, and Backend Integration best practices.
