How to switch back to the production Firebase after connecting a RN app to the Firebase emulator

[hayata-suenaga]

You can connect your development app to the Firebase emulator running on your development device by using firestore().useEmulator(origin, 8080) or auth().useEmulator(http://${origin}:9099).

However, reverting to the production instance is not straightforward. The app appears to keep communicating with the Emulator instead of the production Firebase, even when the useEmulator invocations are commented out. A potential workaround is to uninstall the development client app and reinstall it.

The issue might arise because the default Firebase app instance, once configured to connect to the emulator, continues to do so even after the app restarts.

I attempted to delete the default app instance and reinitialize it, but deleting the default Firebase app instance seems to be impossible.

Does anyone have a solution for smoothly switching between the production and emulator instances?
