Many of the Flutter camera platform interface methods take in a cameraId parameter that is meant to reference the camera currently in use. In the Android implementation of this interface, this ID references the Flutter surface texture used to display a live preview. Because of this, the cameraId parameter often goes unused.

This issue serves as a reminder to update documentation in the android_camera_camerax implementation of the Flutter camera platform interface to be clear about what the cameraId references and whether or not it used for each method that it is a parameter.
