When executing  
`await _zoom.videoHelper.switchCamera(null);`  
the following error occurs:

`PlatformException(ZoomVideoSDK_Error_Invalid_Parameter, deviceId is null or empty, null, null)`

On Android, although an error occurs, the camera still switches.  
On iOS, however, the app crashes.

Hey @tihimsm, sorry you’re facing this issue. I am able to reproduce this error, we’ll fix this in an upcoming release. In the meantime you can use this workaround:

```auto
final cameras = await zoom.videoHelper.getCameraList();
await zoom.videoHelper.switchCamera(cameras[0].deviceId);

```
