Steps to reproduce

Wrap your ProfileScreen() in a MaterialApp() and see this popup on iOS/macOS:

This is unclickable because of the AlertDialog parameters given adaptiveAction() function: https://github.com/firebase/FirebaseUI-Flutter/blob/98a4f0d96af3916db291fc839ac3841ef7ddd09b/packages/firebase_ui_shared/lib/src/universal_alert.dart#L53-L71

Expected Behavior

Expected that AlertDialog() should be clickable if you decide to use MaterialApp() for iOS/macOS. Wrap the ProfileScreen() in CupertinoApp() and everything works fine. And looks like this:

Reason for it working as expected is because of these parameters: https://github.com/firebase/FirebaseUI-Flutter/blob/98a4f0d96af3916db291fc839ac3841ef7ddd09b/packages/firebase_ui_shared/lib/src/universal_alert.dart#L42-L49

Actual Behavior

Forces the developer to use CupertinoApp() for iOS/macOS and MaterialApp() on other devices if you want to use the UI-package.

Additional Information

It could be fixed by adding the adaptive handling by AlertDialog() here: https://github.com/firebase/FirebaseUI-Flutter/blob/98a4f0d96af3916db291fc839ac3841ef7ddd09b/packages/firebase_ui_shared/lib/src/universal_alert.dart#L54

Replace with:

return AlertDialog.adaptive(

But I have seen other PRs removing this feature earlier, so I did not want to push a new PR for "fixing" this. If it suppose to force developers to use CupertinoApp() for iOS/macOS.
