setZoomLevel method
Set the zoom level for the selected camera.
The supplied zoom value should be between the minimum and the maximum supported
zoom level returned by getMinZoomLevel and getMaxZoomLevel. Throws a CameraException
when an illegal zoom level is supplied.
Implementation
Future<void> setZoomLevel(int cameraId, double zoom) {
throw UnimplementedError('setZoomLevel() is not implemented.');
}
