can not scan

[MohammadAIProgramer]

Just add package, import it, use example code.

class _MyApp extends State<MyApp> { late String barcodeScanRes = "-0-"; @override Widget build(BuildContext context) { return Material( color: Colors.transparent, child: GestureDetector( onTap: () async { String scanBarcode = await FlutterBarcodeScanner.scanBarcode( "#ff6666", "CANCEL", true, ScanMode.BARCODE); setState(() { barcodeScanRes += scanBarcode; }); }, child: SizedBox.expand( child: ColoredBox( color: Colors.blue, child: Container( margin: const EdgeInsets.all(100), //child: SvgPicture.string(svgString, semanticsLabel: 'Acme Logo'), child: Text( barcodeScanRes, textDirection: TextDirection.ltr, ), ), ), ), ), ); } } It takes long time, but not scanning. Console errors. Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details. Note: Some input files use unchecked or unsafe operations.

Hi, I had the same issue even on Android 11. It turned out "Google Play Services" package was missing. Last available package requires Android 8...

Good luck! Cezary
