CameraSession

A state object that can be hoisted to control camera, take picture or record video.

To be created use rememberCameraSession.

A session class that holds the current state and information of the camera.

This class serves as a "bridge" to access camera properties such as its current configuration state (CameraState) and hardware information (CameraInfo). It also provides flags indicating the runtime status of the camera, such as whether it is currently streaming or initialized.
