Can't use phone auth on newest version in flutter web

[Ipicon]

Once I try to run signInWithPhoneNumber() I get an error:

I understand the js module is getting auth as unidentified.

Same with signInWithPopup() #9124 ^3.4.2 busted

authExtern is unidentified

Also problem with web FirebaseAuth.instance.authStateChanges(). Not Persisting user anymore instead logs back out.
authStateChanges() returns null once the app reloads.
