Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
beforeFirstRender() → void
inherited
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).
inherited
forceRebuild() → void
Force a rebuild of the current page.
handleAction(Future<void> function(), {dynamic onError(dynamic error)?, String message = '', bool skipBusyState = false}) Future<void>
Perform a future action, catching any exceptions which may occur. This also sets a isBusy flag while the action is being performed.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
