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:

// 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)

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
