PlatformException(PERMISSION_NOT_GRANTED, null, null)

[lijunen2009]

my code try { String barcode = await BarcodeScanner.scan();

  return {
    'status':200,
    'msg':'扫码成功',
    'result':barcode
  };
} on PlatformException catch (e) {
  print(e);
  if (e.code == BarcodeScanner.CameraAccessDenied) {
    return {
      'status':200,
      'msg':'没有相机权限',
      'result':''
    };

  } else {
    return {
      'status':200,
      'msg':'未知错误:${e.toString()}',
      'result':''
    };

  }
} on FormatException{
  return {
    'status':200,
    'msg':'用户取消',
    'result':''
  };
} catch (e) {
  return {
    'status':200,
    'msg':'未知错误:${e.toString()}',
    'result':''
  };
}

I also get this error, even if I use a different plugin to grant permission first - this does not see granted permission and errors with the PlatformException(PERMISSION_NOT_GRANTED, null, null)

Unfortunately, the iOS simulator does not support camera features.
