Frequent asked question thought_balloon

Why there are over-scaled issue when shouldLockPortrait set to false?

Currently the rotate synchronization is not supported. The DeviceOrientation from the CameraValue is different from the one comes from flutter when the user is rotating devices. The preview widget is synchronized when both orientation is the same. Issue: https://github.com/flutter/flutter/issues/78685
