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.

EventListener(String? type, EventCallback<CallbackDataT> callback, {bool once = false, bool protected = false, EventCallbackAdd<CallbackDataT>? onAdd, EventCallbackRemove<CallbackDataT>? onRemove, EventCallbackCall<CallbackDataT>? onCall, EventCallbackCancel<CallbackDataT>? onCancel, bool cancelAdded = true}): Event Listener

appendCallback({EventCallbackAdd<CallbackDataT>? onAdd, EventCallbackRemove<CallbackDataT>? onRemove, EventCallbackCall<CallbackDataT>? onCall, EventCallbackCancel<CallbackDataT>? onCancel}) → void
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.
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.
