Methods
-
add(
Listenable notifier) → void - Adds a new notifier. For GaanaNotifier, check if one with the same key already exists.
-
addListener(

Register a closure to be called when the object changes.
inherited
-
clean(
) → void - Remove all notifiers and clear the list.
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
override
-
get<
T extends Listenable> ({bool predicate(T)?, String? key}) → T? -
Returns the first notifier of type T that matches the optional
predicateor key. if could also return a Notifier by its unique key -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.

Remove a previously registered closure from the list of closures that are
notified when the object changes.
