Kotlin Native Features Integration and backend developer

I already have the full Figma design set and a working Flutter front-end, but I now need the native Android layer completed. Your main task will be to build the Kotlin side of the project in Android Studio so the app can:

• Open the device camera and return captured images or video to the Flutter UI
• Read precise and background location data, streaming updates in real time
• Register and receive push notifications (FCM) while handling deep links and badge counts

All three features must be exposed to Flutter through well-structured platform channels, thoroughly tested on API 23-34, and documented for future maintenance. I’ll provide the existing repository, Firebase keys, and endpoint specs; you push clean, idiomatic Kotlin code plus any Gradle or Manifest changes needed, and a short integration guide so my team can drop your module straight in.

If you enjoy tackling native challenges inside a cross-platform stack, let’s get started right away.
