Description
Steps to Reproduce
- Just run camera demo: https://pub.dev/packages/camera/example
- Tap camera preview area on screen
Expected results:
Focus and exposure function work well
Actual results:
On Android device, only exposure worked, focus doesn't work.
After that, I modify the key code from
cameraController.setExposurePoint(offset); cameraController.setFocusPoint(offset);
to
cameraController.setExposurePoint(offset); cameraController.setFocusPoint(offset); cameraController.setFocusMode(FocusMode.locked);.
Focus and exposure function all work well, but if I move my phone to a very dart environment（or put the camera side on the table）for a minute, the camera will overexposure and never restore, and camera plugin shut down. When I take a photo, the log as follow:
It is worth mentioning that some iOS devices work well without cameraController.setFocusMode(FocusMode.locked);, and some iOS devices need cameraController.setFocusMode(FocusMode.locked); to make focus take effect. But camera plugin
