This package is no longer being updated. Therefore, new features of Android are not supported in this package and will not be supported in the future. I found the solution this way:
I am using the barcode_scan2 package.
Here is the code I used with flutter_barcode_scanner:
String scannerQrcode = await FlutterBarcodeScanner.scanBarcode('#ff6666', 'Cancel', true, ScanMode.QR);
And here is the code I am using with barcode_scan2:
scannerQrcode = await BarcodeScanner.scan(
options: ScanOptions(),
).rawContent;
You can find the available properties of ScanOptions in the package documentation.
