A simple Event Bus using Dart Streams for decoupling applications

Changelog #

Version 1.1.1 (2020-01-21) #

  • Fix homepage URL.

Version 1.1.0 (2019-03-27) #

  • Add constructor for custom controllers like RxDart Subject (see #21).
  • Remove new keyword.

Version 1.0.3 (2019-02-14) #

  • Cleanup and update dependencies.

Version 1.0.0 (2018-07-06) #

  • Migrate to Dart 2.
  • BREAKING CHANGE: The on method now has a generic type. The type must be passed as a type argument instead of a method parameter. Change myEventBus.on(MyEventType) to myEventBus.on<MyEventType>().
  • BREAKING CHANGE: Every EventBus is now hierarchical so that listeners will also receive events of subtypes of the specified type. This is exactly the way that HierarchicalEventBus worked. So HierarchicalEventBus has been removed. Use the normal EventBus instead.

Version 0.4.1 (2015-05-13) #

  • Fix Issue #13: Improve on() stream when no type is specified

Version 0.4.0 (2015-05-03) #

  • BREAKING CHANGE: Moved the HierarchicalEventBus to a separate library to be able to remove dart:mirrors from the normal EventBus.
    Users of the hierarchical event bus must import event_bus_hierarchical.dart and replace the use of the factory constructor EventBus.hierarchical() with the HierarchicalEventBus constructor.

Version 0.3.0 (2014-09-08) #

  • BREAKING CHANGE: Changed and simplified the EventBus API. We can now dispatch any Dart object as an event. Before, we had to create an EventType for every type of event we wanted to fire. Now we can use any class as an event. Listeners can (optionally) filter events by that class.
  • Added a way to create a hierarchical event bus that filters events by class and their subclasses. This currently only works with classes extending other classes and not with implementing an interface. We might have to wait for https://code.google.com/p/dart/issues/detail?id=20756 to enable interfaces.
  • BREAKING CHANGE: The EventBus constructor defaults to async instead of sync!!. This matches the constructor of the Dart Streams and an async event bus might also be the more common use case.
  • BREAKING CHANGE: Removed LoggingEventBus. Reason is that logging can easily be implemented with a event listener that listens for all events and logs them.
