我无法扫描Maxicode条形码Zxing Xamarin

Question

我有下一个代码：

 MobileBarcodeScanningOptions options = new MobileBarcodeScanningOptions();
        options.PossibleFormats = new List<ZXing.BarcodeFormat>() {
            ZXing.BarcodeFormat.MAXICODE
        };
        options.TryHarder = true;

        var scannerPage = new ZXingScannerPage(options);

        scannerPage.Title = "Lector de QR";
        scannerPage.OnScanResult += (result) =>
        {
            scannerPage.IsScanning = false;
            Console.WriteLine(result.Text);
       }

当我尝试读取Maxicode条形码时，切勿进入scannerPage.OnScanResult函数
