Reproducible using the plugin example app and the steps outlined above.
I tested on my Pixel 7.
flutter doctor -v

Set this to P2 because this is a bug I think we take on strictly after fixes are made to support Impeller, which is top priority for the team.

Is there a suggested workaround for this?

Not actively working on this but next steps would be to figure out why we are seeing the
was canceled due to the camera being closed or a new request being submitted" error because we actually swallow the exception due to submitting too many values: https://github.com/flutter/packages/blob/b9ac917daeb0fbf5bd6ad4a7d2a69ab81749d767/packages/camera/camera_android_camerax/android/src/main/java/io/flutter/plugins/camerax/CameraControlHostApiImpl.java#L187-L192.
Thus, this issue is probably caused by another exception. The documentation mentions an
IllegalArgumentExceptionbeing possible so I wonder if it's that and we are trying to support unsiupported exposure compensation index values.mmcdanielq commentedon May 7, 2026
This is not just exposure, I get this error when trying to focus the camera: "Starting focus and metering was canceled due to the camera being closed or a new request being submitted". After receiving this error the camera becomes unusable until restarting it. I'm using the example project in the camera package.
