abhipawar2004/ecommerce_app — reverse-engineered prompt

Build me a Flutter grocery shopping app called Ready Grocery. I want it to feel like a simple ecommerce mobile app where a customer can browse grocery products, view product details with images and prices, add items to a cart, change quantities, and go through a basic checkout flow.

Please make it clean and modern, with reusable screens and widgets, proper assets support, and navigation that works on Android and iOS. The project already looks like a Flutter app with Firebase config, generated image code, and language generation, so wire things up in a sensible way and keep it easy to extend later for real auth, orders, and localization.

Use sample grocery data if there’s no backend yet. Make sure the app runs without crashes, has a nice home screen, categories or featured products, cart total calculation, and basic tests where helpful. Look up current Flutter docs online if you need to.
