Is customAuthDomain setter available?

[devberkay]

I can't find how to use this pr :

#12218

I am using firebase_auth: ^4.19.6 on my flutter app.

here is changelog of ^4.18.0:

FEAT(firebase_auth): add custom auth domain setter to Firebase Auth (#12218). (e1297800)

You should be able to call the setter on the auth instance:

final auth = FirebaseAuth.instance;
auth.customAuthDomain = '....';
