setZoomLevel method Null safety

  1. @override
Future<void> setZoomLevel(
  1. int cameraId,
  2. double zoom
)

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.

Future<void> setZoomLevel(int cameraId, double zoom) async {
  try {
    getCamera(cameraId).setZoomLevel(zoom);
  } on html.DomException catch (e) {

  } on PlatformException catch (e) {
    throw CameraException(e.code, e.message);
  } on CameraWebException catch (e) {
    _addCameraErrorEvent(e);
    throw CameraException(e.code.toString(), e.description);
