Flash not working for single-stream capture

[Kimblebee]

Neither front nor rear flash is functional when the camera is set to single-stream capture mode

Hi Kim, can you verify this issue still exists? I can't seem to reproduce it on device.

Probably related to this CameraX issue regarding flash with OverlayEffect and this issue regarding single-stream mode not really being single stream.

The flash issue should happen only when ImageCapture is merged into StreamSharing. So the second issue is masking the first issue here.

Do we need to file a bug for CameraX? Regardless of whether the ImageCapture is part of StreamSharing or not, I would still expect the flash to fire.

Right, this is ultimately a bug at CameraX side. There are already public bugs filed to CameraX for this and we are working on fixing the issue. It should be fixed soon.
