Dart Flutter Patterns

This is a comprehensive reference for writing production Flutter code the right way. It covers the fundamentals that trip up most teams: null safety patterns that avoid the bang operator, sealed classes for state hierarchies, proper async composition with Future.wait, and the critical mounted check after await. The state management section gives you working examples for BLoC, Riverpod, and Provider instead of making you choose blindly. GoRouter setup includes the refreshListenable pattern for auth guards, Dio examples show token refresh with retry logic, and the testing guidance favors fakes over mocks. The widget architecture advice is spot on: extract to classes not methods, propagate const everywhere. If you're past the tutorial phase and need to see how the pieces actually fit together in a real codebase, this fills that gap.
