Flutter Dual Platform Delivery App

The task is to build a delivery application in Flutter that can be released on both iOS and Android from a single code-base. Three core modules must be fully implemented:

• Real-time tracking – live map view showing driver location and order status updates.
• Payment gateway integration – secure, production-ready checkout (Stripe, PayPal, or a comparable solution we agree on).
• Order management system – place, modify, cancel, and confirm orders with clear status flows for customers and staff.

Clean, well-documented Dart code, state management (Provider, BLoC, or Riverpod), and push notifications are expected so future maintenance is straightforward. When finished, I will need:

1. The complete Flutter source code.
2. Separate debug builds for iOS and Android.
3. A short setup/compile guide so I can reproduce the builds locally.

Feel free to suggest additional best-practice touches such as analytics hooks or CI/CD scripts if they fit naturally into the scope.
