Bloc
A predictable state management library for Dart and Flutter that implements the BLoC design pattern.
What is Bloc?
Bloc is a state management library for Dart and Flutter that helps implement the BLoC (Business Logic Component) design pattern. It provides a predictable way to manage application state by separating business logic from presentation, making it easier to test, debug, and maintain complex applications. The library includes core packages for Flutter, AngularDart, and pure Dart, along with tools for testing, persistence, and concurrency control.
Flutter and Dart developers building medium to large-scale applications who need a structured, testable approach to state management. It's particularly useful for teams working on cross-platform projects where business logic needs to be shared between mobile and web.
Developers choose Bloc for its strong separation of concerns, excellent testability, and predictable state transitions. Its rich ecosystem of supporting packages and extensive documentation make it a robust choice for production applications, while its platform-agnostic core allows logic reuse across Flutter, AngularDart, and pure Dart projects.
