🐛 [firebase_auth] linkWithCredential throws Exception operation-not-allowed even when provider is enabled #11661
Description
Bug report
When I setup a Firebase Project and enable Anonymous and Email/Password Auth providers:
and I perform FirebaseAuth.instance.signInAnonymously(), it works:
but when after that I perform:
final credential = EmailAuthProvider.credential(
email: 'vincent@email.com', password: 'Flutter123!');
FirebaseAuth.instance.currentUser
?.linkWithCredential(credential);it throws:
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: [firebase_auth/operation-not-allowed] The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section. [ Please verify the new email before changing email. ]

I would expect this action to be successful since the Anonymous provider is enabled.
On the other hand, FirebaseAuth.instance.createUserWithEmailAndPassword(email: 'vincent+1@email.com', password: 'Flutter123!'); works.
Steps to reproduce
Steps to reproduce the behavior:
- Launch the sample project
- Click on "Sign-in anonymously"
- Click on "Link with credentials"
- Assess the error in the logs.
Expected behavior
I would expect the method FirebaseAuth.instance.currentUser?.linkWithCredential(credential); to work when the Anonymous provider is enabled.
