A grocery e-commerce app built with flutter. Used an approach which doesn't use any of of the third-party state management solutions in Flutter. The only third-party package used was GetIt, to provide a reference to a plain Dart class where you’ll manage your own state. Used Flutter’s own built-in ValueNotifier and ValueListenableBuilder classes for UI which makes it easy to integrate and with proper code structuring. The project involved UI without integrating any APIs. Loaded static data in a json file to work on the business logics to ease integration of API into the Flutter project whenever it is ready.

A @nuel_nartey Flutter Showcase project.
