Overview
rx_bloc is a Flutter package that simplifies the implementation of the BLoC (Business Logic Component) design pattern by leveraging reactive streams. It enables developers to manage state and business logic in a clean, testable, and scalable way using RxJava-style reactive programming with Dart's Stream and BehaviorSubject. The package promotes separation of concerns, making it easier to handle complex state transitions and asynchronous operations across platforms.
