[BUG]

If i increase the scanning area in this code Widget _buildQrView(BuildContext context) {
// For this example we check how width or tall the device is and change the scanArea and overlay accordingly.
var scanArea = 400.0;
// var scanArea = (MediaQuery.of(context).size.width < 400 ||
// MediaQuery.of(context).size.height < 400)
// ? 150.0
// : 350.0;
// To ensure the Scanner view is properly sizes after rotation
// we need to listen for Flutter SizeChanged notification and update controller
return QRView(
key: qrKey,
onQRViewCreated: _onQRViewCreated,
overlay: QrScannerOverlayShape(
borderColor: Colors.blue,
borderRadius: 10,
borderLength: 30,
borderWidth: 10,
cutOutSize: scanArea),
onPermissionSet: (ctrl, p) => _onPermissionSet(context, ctrl, p),
);
} it just increases the overlay size not the actual scanning area , the actual scanning happens on a very small area that is in the center of the bigger scanning area (Overlay area)
