A sample Flutter app that shows how to manage responsive state using the leadding state management patterns

• Using a BLoC pattern for global app state
• Using the BlocProvider pattern for accessing the model
• Using BehaviorSubject methods to make elements reactive

• Using a provider for global app state
• Using a provider as a view model for a screen
• Using ChangeNotifierProvider<T> to make the app reactive
• Consumption of providers using Provider.of<T>(context) method

• Using a ProviderScope for global app state
• Using a StateNotifier for the model for a screen
• Using StateNotifierProvider to make the app reactive
• Consumption of providers using ref.watch and ref.read method

• App and screen state saves when changed and is loaded on startup
• An instrance of SharedPreferences is created globally as a singleton
• Providers are able to save and load their own state
