Flutter Medicine Delivery based on sample app

I already have a reference online-medicine delivery application and I need an exact functional clone built with Flutter. The finished customer app has to compile smoothly for both iOS and Android from a single code-base, and I also need its accompanying web-based admin panel so I can manage users, inventory, orders and payments in real time.

You will be working with Flutter, Dart and a backend stack of your choice (Firebase, Node, Laravel, etc.) as long as the final build is stable, well-documented and easy for me to maintain. Clean architecture, state management (Bloc, Provider or Riverpod), and proper separation between front-end and back-end are essential.

Deliverables:
• Complete Flutter source code for the customer app, ready for release on App Store and Play Store
• Web admin panel with authentication and full CRUD on products, orders and users
• API layer (REST or GraphQL) documented with Postman collection or Swagger
• Installation guide and one round of deployment support on my servers

Please mirror the UI/UX flow of the reference app as closely as possible while keeping the codebase modular so future feature additions (wallet, e-prescriptions, etc.) are straightforward. Let me know the timeline you need and any previous Flutter marketplace or delivery apps you can show.
