Flutter Developer Builds Sneaker Shop App to Master Provider State Management

A Flutter developer built a minimal cart management app called 'Sneaker Shop' to deeply understand Provider-based state management rather than relying on copied code. The project centered on the ChangeNotifier class, where a CartProvider stored cart data and used notifyListeners() to update the UI whenever items were added, removed, or cleared. The developer used AI as a pair programmer — letting it generate skeleton code first, then rewriting everything by hand to build genuine understanding and muscle memory. This hands-on approach led to 69 compile-time errors, all traced to minor typos and missing imports rather than any logic flaws. The exercise helped the developer move beyond memorization and grasp the practical difference between context.read and context.watch for optimizing UI rebuilds.
