same problem here, Samsung Galaxy S9, Android 10 installed.

btw, this shouldn't be happening again, because i remember have fixed it at the latest version, have you tried the latest version?

[mcsugaman]

yes, I am using version 1.1.1+1. When I call cameraController.switchCamera() I get this error.

[mcsugaman]

any update on this?

I have this issue using the current example app too. Tested on Samsung A21s running Android 10.

it's Ok in rear but when i switch camera to Front.
in version adv_camera 1.1.2+2, I got this :
"a virtual display of size: [1631, 2900] may result in problems(flutter/flutter#2897 is larger than the device screen size: [1440, 2900]."

I used the version, where front camera was working and then added autofocus implementation...works like a charm

[ricnaaru]

please use the latest version (1.2.0) and if the problem still persists, reopen this thread. Thanks!
