Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void: The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
close() → void: The close() method of the Notification interface is used to close/remove a previously displayed notification.
dispatchEvent(Event event) → bool: The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void: The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
