PropertyChangeModel<T extends PropertyChangeNotifier<S>, S extends Object> class

The InheritedModel subclass that is rebuilt by _PropertyChangeProviderState whenever its PropertyChangeNotifier is updated. Notifies dependents when the names of the changed properties intersect with the list of properties provided to the PropertyChangeProvider.of method. The type parameter T is the type of the PropertyChangeNotifier<S> subclass. The type parameter S is the type of the properties to observe.
