Dart Expert

This is a comprehensive reference for Dart language features and Flutter development, covering everything from null safety and async patterns to widget composition and state management with Provider. The code examples are practical and production-ready, showing real patterns like StreamControllers, named routes, and proper error handling. What stands out is the depth on fundamentals like mixins, extensions, and Futures before diving into Flutter specifics. Use this when you need quick reminders on Dart idioms or Flutter architecture patterns without digging through documentation. The state management section focuses on Provider, so if you're using Riverpod or Bloc exclusively, you'll need to adapt those patterns yourself.
