I am using ZXing to scan barcode in a Xamarin Forms app in a custom layout. How can I select the default camera as front camera. Their is no option to select the default camera.

    <zxing:ZXingScannerView Grid.Row="1" x:Name="_scanView" OnScanResult="Handle_OnScanResult" IsScanning="true" WidthRequest="200" HeightRequest="200"  />

You can do it in the Options which is of type MobileBarcodeScanningOptions. That has a property called UseFrontCameraIfAvailable.

To set it from code, do this: _scanView.Options = new MobileBarcodeScanningOptions { UseFrontCameraIfAvailable = true; }

From XAML is a bit more extensive but not undoable:

<zxing:ZXingScannerView Grid.Row="1" x:Name="_scanView" OnScanResult="Handle_OnScanResult" IsScanning="true" WidthRequest="200" HeightRequest="200">

    <zxing:ZXingScannerView.Options>

        <zxcore:MobileBarcodeScanningOptions UseFrontCameraIfAvailable="true" />

    </zxing:ZXingScannerView.Options>

</zxing:ZXingScannerView>

You might need to import a different XAML namespace for the options object. I don't have an actual project at hand to try, but I'm sure you will figure that one out.
