did not scan barcode/QRcode for web

[javaone199]

Followed the example, and added the script to the index.html for web.

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: MobileScanner(
        controller: MobileScannerController(
          detectionSpeed: DetectionSpeed.normal,
          facing: CameraFacing.front,
          torchEnabled: true,
        ),
        onDetect: (capture) {
          final List<Barcode> barcodes = capture.barcodes;
          final Uint8List? image = capture.image;
          for (final barcode in barcodes) {
            debugPrint('Barcode found! ${barcode.rawValue}');
          }
        },
      ), 
    );
  }
}

The camera is open after permission is granted. But the app(windows, chrome web) did not scan barcode and QR code that is focused in camera. No scan window and nothing happened.

Your code sample indicates that you are using an older version of mobile_scanner. Could you try this with the latest beta release? The beta 3 release does fix an issue on the web relating to the camera freezing the second time, but you should be able to test your issue with it.
