Scanner plugin does not return scanned result.

[Petpokoh]

Hi thanks to a very handy package. Please I just added the flutter_ barcode_scanner package to my app. And when I tested it. It showed the camera window, scanned a barcode, detected it and pops out. But it does not return the scanned result . it just hangs at the function call and does not continue after the call to
BarcodesscanRes = await FlutterBarcodeScanner.scanbarcode('#ff6666', 'Cancel', true, scanMode.Barcode);
The code hangs here and doesn't continue to display the result

I am testing on Vivo android 7 phone.

Regards.
