Additional information #
If you have questions please let me know. This package should remove most of the boiler-plate codes that you wrote in order to get an image from camera controller image stream. Works well with anything AI releated. You can do various image processing on the cameraImage once it is passed to you inside the onCameraImageAvailable method.
