You can use the code-behind the view for the actions. And use the VM for other properties

XAML:

 <zxing:ZXingScannerView
        IsAnalyzing="{Binding IsAnalyzing}"
        IsScanning="{Binding IsScanning}"
        OnScanResult="CameraScanner_OnScanResult" />

Code behind:

private void CameraScanner_OnScanResult(ZXing.Result result)
        {   
             ((MyViewModel)BindingContext).OnScanComplete(result.Text);
        }
