Dart Flutter Patterns

affaan-m/ecc

Production Dart and Flutter patterns that cover the stuff you actually need: null safety without bang operators, sealed classes for state hierarchies, async composition with Future.wait, and the widget architecture rules that prevent rebuilds. It walks through BLoC, Riverpod, and Provider with real examples, plus GoRouter setup with reactive auth guards and Dio interceptors with token refresh. The testing section shows you how to wire up BLoC tests and ProviderScope overrides. Honestly, this is the reference you keep open when setting up a new feature or reviewing code that feels off. It's opinionated where it needs to be, like preferring widget classes over methods and being strict about mounted checks after await.

  • Setting up a new Flutter project and choosing between BLoC, Riverpod, or Provider
  • Implementing secure HTTP clients, WebView integration, or local storage
  • Writing tests for Flutter widgets, Cubits, or Riverpod providers
  • Wiring up GoRouter with authentication guards
