override
initState() → void: The method to be executed when initialization is performed.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

notifyListeners() → void: Call all the registered listeners.
override
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
