SardarHossaini/E-commerce-App — reverse-engineered prompt

Build me a clean Flutter e commerce mobile app that feels modern and simple to use. I want users to open the app, browse a list of products with images and prices, tap a product to see more details, and use a shopping cart screen or cart interface so it feels like a real online shopping app.

Please keep it lightweight and focused on the UI, navigation, and good structure rather than payments or a real backend. Use sample products and local images if needed. Make it responsive and polished for mobile, with Material style components, nice spacing, clear buttons, and a smooth shopping flow.

Set up the project so the code is organized into screens, widgets, and models, and make sure it runs with flutter run. If anything is missing, use reasonable demo data and look up current Flutter docs online if you need to.
