Describe your issue. If applicable, add screenshots to help explain your problem.

Good News. Android CameraX supports now NV21 but it is in Format yuv420. So InputImage has problems like descibed here: flutter/packages#9853 (comment)

Configuring NV21 image format
If you initialize a CameraController with ImageFormatGroup.nv21, then streamed images will still have the ImageFormatGroup.yuv420 format, but their image data will be formatted in NV21. See https://developer.android.com/reference/kotlin/androidx/camera/core/ImageAnalysis#OUTPUT_IMAGE_FORMAT_NV21().

Steps to reproduce.
