Building a custom Login screen in Xamarin mobile app

I am trying to build a custom login screen instead of using Okta sign in page for my Xamarin mobile app. I could not find anything in the documentation for Xamarin. The only option for me is to use the Okta Authentication API from the mobile app. Does anyone have any other solution ?
