CameraController()with aCameraDescriptionthat you get from theawait availableCameras()method - Call the
controller.dispose()inside theonDispose()method - Wait that your Android phone automatically goes to the locked mode (inactivity) and you get the error.
Expected results: No error shown in the logs.
Actual results:

Can't test it on IOS as Xcode doesn't allow the Auto-Lock screen mode while debugging so I can't get the output...
The issue happened on all my Android 10 devices (Motorola, OPPO, Samsung).
I was posting on this issue #55434 and was asked to create a new one instead.
This error ONLY happens in the auto-lock screen mode as weird as it seems :
- If I lock the screen myself, no error is shown (on IOS it's also working in this case).
- If I put the app in background and come back, no error is shown either on both Platforms.
- I have tested all combination of these 2 tests above, and when manually interacting with the app or the Lock Screen, no problems are detected.
I also add that I am using the version 0.8.1 of the camera package.
