## What it does

The skill gives the agent a working frame for Flutter projects. Inside is guidance on widget composition, state management patterns (Provider and BLoC), navigation, and API integration, plus a set of rules: don't build whole screens inside `build()`, don't fire network calls from `build()`, use `const` constructors, dispose resources in the state lifecycle.

Three reference guides sit in `references/`: project structure and navigation, state management with Provider, and screens with Provider integration. The quick start shows a `pubspec.yaml` with `provider`, `http`, and `go_router`, and a `main.dart` sketch using `MaterialApp.router`. Full implementations live in the guides.

The skill targets iOS and Android, and you will have to check both. Testing across device sizes and accounting for platform differences are spelled out in the rules. On a different stack there is nothing here for you.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill flutter-development -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/flutter-development/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/flutter-development/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill flutter-development -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/flutter-development/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill flutter-development -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/flutter-development/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts flutter-development
```

2. **Manually: put the files in place**
- File: `.github/skills/flutter-development/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill flutter-development -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/flutter-development
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/flutter-development/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill flutter-development -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/flutter-development/SKILL.md

## When to use it
- lay out a Flutter project structure with navigation
- move state out of `setState` into Provider or BLoC
- wire up HTTP calls to an API without touching `build()`
- split a screen into widgets instead of one large `build()`
- set up routing with `go_router`

## Example prompts
- help me plan a Flutter app structure with go_router
- rewrite this screen so state goes through Provider
- check my `main.dart` against the rules in the skill

- [Best Practices](#best-practices)

## Overview

Create high-performance, visually stunning mobile applications using Flutter with Dart language. Master widget composition, state management patterns, navigation, and API integration.

## When to Use

- Building iOS and Android apps with native performance
- Designing custom UIs with Flutter's widget system
- Implementing complex animations and visual effects
- Rapid app development with hot reload
- Creating consistent UX across platforms

## Quick Start

Minimal working example:

```dart
// pubspec.yaml
name: my_flutter_app
version: 1.0.0

dependencies:
  flutter:
    sdk: flutter
  provider: ^6.0.0
  http: ^1.1.0
  go_router: ^12.0.0

// main.dart with GoRouter navigation
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
// ... (see reference guides for full implementation)
```

## Reference Guides

Detailed implementations in the `references/` directory:

| Guide | Contents |
|---|---|
| [Project Structure & Navigation](references/project-structure-navigation.md) | Project Structure & Navigation |
| [State Management with Provider](references/state-management-with-provider.md) | State Management with Provider |
| [Screens with Provider Integration](references/screens-with-provider-integration.md) | Screens with Provider Integration |

## Best Practices

### ✅ DO

- Use widgets for every UI element
- Implement proper state management
- Use const constructors where possible
- Dispose resources in state lifecycle
- Test on multiple device sizes
- Use meaningful widget names
- Implement error handling
- Use responsive design patterns
- Test on both iOS and Android
- Document custom widgets

### ❌ DON'T

- Build entire screens in build() method
- Use setState for complex state logic
- Make network calls in build()
- Ignore platform differences
- Create overly nested widget trees
- Hardcode strings
- Ignore performance warnings
- Skip testing
- Forget to handle edge cases
- Deploy without thorough testing
