How to keep the rear camera fixed in Flutter (Android),after app lifecycle changes?

I'm using the Agora Flutter SDK for video broadcasting, and I manually switch to the rear camera using the switchCamera() method.

The issue is that whenever the app is minimized, paused, or goes through a lifecycle change (e.g., background → foreground), the camera automatically resets to the front camera when the session resumes.

I want to keep the rear camera fixed across all lifecycle states without switching back to the front camera each time.

Is there any way to:

Set the rear camera as default before joining the channel, or

Persist the camera selection across lifecycle events?
