SetState class
Used like the function, setState(), to 'spontaneously' call build() functions here and there in your app. Much like the Scoped Model's ScopedModelDescendant() class. This class object will only rebuild if the App's InheritedWidget notifies it as it is a dependency. More information: https://medium.com/flutter-community/shrine-in-mvc-7984e08d8e6b#488c
