Xamarin.forms Scanners Xamarin.UITest

How can I trigger scan process and pass custom data programmatically?

Hi. I'm trying to figure out how to not only trigger barcode scanner programmatically, but also how to pass custom data there without need to do any physical actions with device. I found out that code samples contain code for triggering and toggling scanner, but I didn't find how to pass my custom data there so far. I made attempt to create custom DataEventArgs object with data that I need, but I didn't succeed in that so far as well.
