Bloc is a predictable state management library for Dart, Flutter, and AngularDart that implements the BLoC (Business Logic Component) design pattern. It provides a rich ecosystem of packages including Flutter widgets, testing utilities, persistence, undo/redo, event transformers, and linting tools.
Use cases
- manage app state in a flutter app
- separate business logic from ui in dart applications
- implement predictable unidirectional data flow
- add undo and redo to app state
- persist state across app restarts
- test state changes in flutter apps
- control how concurrent events are processed
When to choose
- building medium-to-large Flutter apps needing structured, testable state management
- teams wanting a strict, predictable architecture with strong conventions
- projects requiring state persistence, replay, or concurrency control out of the box
When to avoid
- small prototypes where setState or a lightweight solution suffices
- developers who prefer minimal boilerplate and implicit state management
- non-Dart/non-Flutter projects
