inherited
-
dispose(
) → void -

Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.

-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
setFutureValue(
WhenFuture< T> whenFuture, FutureSnapshotListenerCallback<T> ? listener, VoidCallback? onFinally) → Future<void> - Sets a value after an asynchronous computation that returned a future
-
toString(
) → String -
