Hello! I am looking to implement this with a Flutter mobile app. Seems to me this is mostly for the web. I want to have native apple login and google as well, how does that work with the Flutter sdk? Seems like you cant tap into the actual handshake process, is it all handled through an in-app browser? Or how does the social logins work on mobile? I am using FusionAuth currently and that works, its just so ugly and clunky for our uses so looking to change.
