[Bug]

[daveparks23]

Describe the bug Android only. iOS works fine. The scan does not return anything.

To Reproduce Steps to reproduce the behavior: I trigger the scan function. The camera starts up and works fine. Once the barcode has been read the app returns to the screen where the data should appear. And there is no data. The code after

ScanResult result = await BarcodeScanner.scan(options: options);
setState(() => scanResult = result);
print('Gotaresultforbarcode');

The print never occurs in the console.

Expected behavior Scan a barcode or qr code and get a result.

Environment (please complete the following information):

        type: ResultType.Error,
        format: BarcodeFormat.unknown,
      );

      if (e.code == BarcodeScanner.cameraAccessDenied) {
        setState(() {
          result.rawContent = 'The user did not grant the camera permission!';
        });

      } else {
        result.rawContent = 'Unknown error: $e';
      }
      setState(() {
        scanResult = result;
      });
      return result.rawContent;
    }   
  }
