Flutterfire: 🐛 [firebase_auth] Incompatible with latest flutter_localizations master channel.

[ekasetiawans]

Reported by @Macacoazul01 on flutter repo. flutter/flutter#71801

I've tried to use flutter localizations package on my app to change the showdatepicker widget language, but when i add it to my pub there is a conflict with firebase auth:

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations: # Add this line
    sdk: flutter
  firebase_auth: ^0.18.4
  firebase_core: ^0.5.3

[assets_apps] flutter pub get
Running "flutter pub get" in assets_apps...                     
Because firebase_auth >=0.18.4 depends on firebase_auth_web ^0.3.2+2 which depends on intl ^0.16.1, firebase_auth >=0.18.4 requires intl ^0.16.1.

And because every version of flutter_localizations from sdk depends on intl 0.17.0-nullsafety.2, firebase_auth >=0.18.4 is incompatible with flutter_localizations from sdk.

So, because assets_apps depends on both flutter_localizations any from sdk and firebase_auth ^0.18.4, version solving failed.
pub get failed (1; So, because assets_apps depends on both flutter_localizations any from sdk and firebase_auth ^0.18.4, version solving failed.)
exit code 1

Is there any way of changing the lang of the datepicker to pt-br that doesn't use the flutter_localizations?

Reproducible on the latest master 1.25.0-5.0.pre.91.

flutter doctor -v

They've told me to reopen the issue here on flutterfire, but seems it's already made by the team.
Like @markusaksli-nc said, the error happens in the latest master too.

Does anyone know a working version pair of firebase_auth and flutter_localizations?
I'm currently having this issue and don't know which version I should roll back to.

[visit1985]

Beta (1.24.0-10.2.pre) works with latest firebase_auth. Unfortunately I have other dependencies that break when I switch to beta.

I just downgraded Flutter to v1.22.4 and everything started to work again!
