noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
notifyListeners() → void
Call all the registered listeners.
observe(List<Observable> observables, {bool reset = true}) → void
Listen to observables changes and call notifyListeners when a new value is added to the stream.
onBuild() → void

onDependenciesChange() → void
A callback when the MVVM widget's didChangeDependencies is called.
