Using Firestore instances after hot restart

[pti]

The app I'm working on uses Firestore from Flutter and native code (Android), and both use the same Firestore (db) instance. By hot restarting the app, it seems that in didReinitializeFirebaseCore the db instance gets terminated [link]. So the native code needs to stop using the terminated instance and get a new reference to the newly created instance for the native side to work correctly after hot restarting.

Would it be possible to make the terminate-instance-on-hot-restart functionality optional, or are there some other ways the SDK is intended to be used in similar cases?

I haven't noticed any issues outside hot restarting, e.g. destroying the main activity and then returning back to the app (native side continued running and Flutter starts fresh), or on iOS.

When you hot restart a Flutter app:

1. Flutter reinitializes Firebase and terminates the existing Firestore instance.
2. Your native Android code still holds a reference to the old Firestore instance, which is now invalid or terminated.
   This causes issues only during development, not in production.

Recommended Solution (Safe & Practical)
You need to detect when Firebase is reinitialized on the Flutter side, and notify the native side to recreate Firestore.

Note: you cannot keep the running Firebase instance during a hot restart in Flutter.
