[camera_android_camerax] Setting exposure compensation index was canceled due to the camera being closed or a new request being submitted

[Correct-Syntax]

Steps to reproduce

1. Create a new flutter project and paste in the code from https://github.com/flutter/packages/blob/main/packages/camera/camera/example/lib/main.dart
2. Add camera, video_player, and permission_handler dependencies in pubspec.
3. Add CAMERA permission to AndroidManifest.xml.
4. Run the app in debug mode
5. Accept the permission
6. Tap on Exposure mode and slide the slider
7. The error Setting exposure compensation index was canceled due to the camera being closed or a new request being submitted stops the session.

This is on a Samsung Galaxy A53 running Android 14.

Expected results

Adjusting the exposure (EV) slider should not cause errors.

Actual results

Exception: Setting exposure compensation index was canceled due to the camera being closed or a new request being submitted

Is the exposure still changing? My understanding is that continuously modifying the exposure can cause this log message if send too frequently.

If the exposure is not changing this is bug. If the exposure is changing then this might be a physical or api limitation of changing exposure and is works as intended.

[Correct-Syntax]

@reidbaker Seems the answer is no. At least testing in DEBUG mode, everything freezes the instant the exception occurs -which is the instant the slider is moved. The preview never updates so I don't know if the exposure is changing. I would share a video, but there really is nothing other than a frozen screen to see. 😄

Wouldn't this be a problem with the flutter CameraX and/or CameraX implementation rather than a physical or underlying api limitation since this does not happen with Camera2?

[flutter-triage-bot]

This issue is missing a priority label. Please set a priority label when adding the triaged-android label.

[camsim99]

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.
