Flutter Recharge API Integration

I’m enhancing my existing Flutter app with end-to-end recharge and bill payment capabilities. The backend team has finished all the REST APIs, so I now need a Flutter developer who can wire them into the mobile front-end quickly and cleanly.

The scope covers three transaction flows:
• Mobile recharge
• Utility bills payment
• TV subscription payment

You’ll connect each flow to its respective endpoint, build the request/response models, and surface clear in-app screens for amount entry, confirmation, progress, and success/failure receipts. Robust error handling, loading states, and simple validation are important so the user experience feels polished.

I’ll provide:
• Full API documentation, base URLs, and keys
• Existing project repo (clean Flutter 3 codebase)
• Sample JSON responses for testing

I expect:
• Well-structured Dart services for each API group
• Modular widgets that follow current app theming
• Thorough in-app testing showing successful transactions for all three services
• A short hand-off note (endpoints used, files edited, and any setup steps)

If you’ve integrated payment or recharge APIs before and are comfortable with REST, Dio/http, Provider or Bloc, let’s get started.
