EventBus class

A singleton EventBus

EventBus's Event are subscribed by EventRule subscribe to call corresponding EventListener's callbacks.

Example

final event1 = Event<int>("int");

EventRule<int>(event1, targets: [

  // On Receiving `event1` call `onEvent`
  // with `payload` of type [int]
  EventListener(
    (payload) {
      print("integer event: $payload");
    },
  ),
]);


....

// Release Event
EventBus.emit(event1.createPayload(100))

// prints "integer event: 100"
