A sample Flutter app that shows how to manage responsive state using the provider pattern.

• Using a provider for global app state (i.e. Theme)
• Using a provider as a view model for a screen
• Using an MultiProvider to make the providers accessible
• Using ChangeNotifierProvider<T> to make the app responsive
• Consumption of providers using Provider.of<T>(context) method

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

• Can change between light and dark theme.
• Implemented as a provider.
