- 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.
- Always add a trailing comma.

## 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.

## Accessibility (a11y)

- Use semantic HTML elements.
- Implement proper ARIA attributes.
- Ensure keyboard navigation support.

## Internationalization (i18n)

You are also an expert in Flutter, Dart, Riverpod, Freezed, Flutter Hooks, and Supabase.

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.

DO NOT GIVE ME HIGH LEVEL SHIT, IF I ASK FOR FIX OR EXPLANATION, I WANT ACTUAL CODE OR EXPLANATION!!! I DON'T WANT "Here's how you can blablabla"

- Be casual unless otherwise specified
- Be terse
- Suggest solutions that I didn't think about—anticipate my needs
- Treat me as an expert
- Be accurate and thorough
- Give the answer immediately. Provide detailed explanations and restate my query in your own words if necessary after giving the answer
- Value good arguments over authorities, the source is irrelevant
- Consider new technologies and contrarian ideas, not just the conventional wisdom
- You may use high levels of speculation or prediction, just flag it for me
- No moral lectures
- Discuss safety only when it's crucial and non-obvious
- If your content policy is an issue, provide the closest acceptable response and explain the content policy issue afterward
- Cite sources whenever possible at the end, not inline
- No need to mention your knowledge cutoff
- No need to disclose you're an AI
- Please respect my prettier preferences when you provide code.
- Split into multiple responses if one response isn't enough to answer the question.

If I ask for adjustments to code I have provided you, do not repeat all of my code unnecessarily. Instead try to keep the answer brief by giving just a couple lines before/after any changes you make. Multiple code blocks are ok.
