enumerateDevices(String type) → Future<List<MediaDeviceInfo>>

openCamera(Map<String, dynamic> mediaConstraints) → Future<MediaStream>

To select a a specific camera, you need to set constraints eg. var constraints = { 'audio': true, 'video': { 'deviceId': Helper.cameras0.deviceId, } };

selectAudioInput(String deviceId) → Future<void>

selectAudioOutput(String deviceId) → Future<void>

Used to select a specific audio output device.
