Modern Android Flutter E-Commerce

I need a sleek, production-ready e-commerce application built for Android with Flutter (Material 3) on the front end and Firebase on the back end.

Core scope
• Secure Firebase Authentication for sign-up, sign-in and password reset
• Cloud Firestore data layer powering product catalogues, search, categories, wish-lists, carts and user profiles
• Modern, clean UI that adapts gracefully to all common Android phone sizes, following Material 3 guidelines
• Features: product browsing grid, detailed product pages, live search with filters, favourites/wish-list toggle, persistent shopping cart, checkout hand-off placeholder, editable profile section and splash/on-boarding screens

What I expect
• Well-structured, commented Dart code with clear separation of concerns
• Responsive layouts, smooth state management (Provider, Riverpod or Bloc—use what you do best)
• Firestore security rules and seed data scripts
• A brief README explaining build steps, Firebase setup and any third-party packages used

Please share links or screenshots of past Flutter work that shows similar functionality or design polish; I will shortlist based on that. I’m aiming for a clean hand-over: full source, reproducible build and a signed APK ready for Play Console upload.
