Learn to manage Flutter app state cleanly with the Provider package: model your state in ChangeNotifier classes, expose it with ChangeNotifierProvider, and rebuild only the widgets that care using Consumer and context.watch/read. You will finish able to separate UI from logic and wire up a real shopping-cart feature that scales beyond setState.
