Pain

Mobile app developers end up looking for a way to call ASWebAuthenticationSession on iOS and Custom Chrome Tabs on Android when they want to implement a secure authentication feature. Although this package offers WebAuthenticationSession and ChromeSafariViewBrowser to implement such a feature, WebAuthenticationSession is missing a parameter that expects UniversalLinks, so the developers currently have to either stick with Custom URL Scheme or look for another package that offers the latest version of ASWebAuthenticationSession.

I understand that Custom URL Scheme does not lead to any security issues in this senario, but it does when used on Android. This means that sticking with Custom URL Scheme leads to a need of managing a Custom URL Scheme for iOS and an AppLink for Android on one feature which can quite a bit of pain if a project leader expects little platform-specific requirements with Flutter.

Suggested solution

To support UniversalLinks (i.e. deeplinking strategy that starts uses https) on iOS, WebAuthenticationSession API in this awesome package needs to have a parameter that expects https URL.

Perhaps, it could be even better if one could combine the latest ASWebAuthenticationSession and CustomChromeTabs into one API so that developers do not have to write switch-case statement on an authentication feature for iOS and Android.
