CaptureDeviceDiscoverySession class Null safety

A query for finding and monitoring available capture devices.

Use this class to find all available capture devices matching a specific device type (such as microphone or wide-angle camera), supported media types for capture (such as audio, video, or both), and position (front- or back-facing).

After creating a device discovery session, you can inspect its devices list to choose a device for capture.
