BLoC State Management (v9.x)

Goal

Strict separation of UI from business logic via event-driven unidirectional data flow. Choose Cubit (lightweight, no events) for simple state, or full Bloc (events + transformers) for complex flows.

Process

1. Install Dependencies

dependencies:
  flutter_bloc: ^9.1.1
  equatable: ^2.0.5
  bloc_concurrency: ^0.3.0  # For event transformers
