StreamEventListener<T> class

Stream Event Listener

A listener is a subscription to a specific event type and data type.

This includes all the information needed for how to react with an event emitter.

This specific listener also includes a Stream to listen to. The callback property is optional, useful to return the callback satisfaction.

call<T extends Event>(T event) → bool: Checks if the listener matches the event. If the event is valid, the callback will be called.

cancel() → void: Cancel the listener.

close() → void
matches<T>([String? type, EventCallback<T>? callback]) → bool: Checks if the listener matches the event type, data type and callback.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

toString() → String: A string representation of this object.

validate<T extends Event>(T event) → bool: Checks if the listener matches a given event.
