FlutterWebQrcodeScanner(

onGetResult: (result) {
// _result = jsonDecode(result);

//width:200,
//height:200,

You are able to choose the scanning camera via the cameraDirection attribute CameraDirection.back or CameraDirection.front,
If you want to control the start and stop of camera scanning, you must use the CameraController attribute
CameraController _controller = CameraController(autoPlay: false);
