Mr. Developer

First of all, thank you very much for the wonderful effort of this innovation

To be honest, it is a very wonderful library in terms of reading speed and image capture speed
I really can't describe it

But as you know, your followers are always greedy lol :)

I tried to use the view MVVM , but it didn't work for me

And I think it's largely due to my weak programming experience

Can you put us a code for the view model

And I also hope that the next update will take a picture of the qrcode itself and not the full screen

Because there is definitely a category that will need to pass a picture of the QR code, for example, to make sure there is a logo or something similar for the sake of machine learning

It's just an idea

And for the second time, thank you, thank you :)

in your XAML:

<scanner:CameraView
  x:Name="qrScanner"
  TapToFocusEnabled="True"
  CameraFacing="{Binding CameraFacing}"
  TorchOn="{Binding TorchOn}"
  AimMode="{Binding AimMode}"
  BarcodeSymbologies="QRCode"
  VibrationOnDetected="False"
  OnDetectionFinishedCommand="{Binding HandleQRCodeCommand}"
  PauseScanning="{Binding PauseScanning}"/>

in your viewmodel:

public Command HandleQRCodeCommand { get; }
private async void HandleQRCode(object o)
{
  if (o is BarcodeResult[] result)
  {
    if (result.Length > 0)
    {
      if (result[0].BarcodeFormat == BarcodeFormats.QRCode)
      {
        PauseScanning = true;
        Vibration.Vibrate(100);
        // Handle result[0].DisplayValue here
        PauseScanning = false;
      }
    }
  }
}

in ctor of your vm:

HandleQRCodeCommand = new Command(HandleQRCode);

in code-behind of your page:

protected override void OnAppearing()
{
  base.OnAppearing();
  qrScanner.CameraEnabled = true;
}

protected override void OnDisappearing()
{
  base.OnDisappearing();
  qrScanner.CameraEnabled = false;
}

I have not listed other implemented properties here.
Also I disabled build-in vibration, because it lasts too long and couldn't be changed.

Hope it will be helpful for your purposes.

In v1.7.0 and v2.1.0 type of command parameter was changed from BarcodeResult[] to HashSet<BarcodeResult>.

Returning to your recent question (#116), the versions I mentioned in this comment works fine with MAUI v9.0.10 and VisualStudio 17.13.0 Preview 1.0 on Xiaomi 13 device with Android 14.
