🐛 [firebase_auth_web] unnecessary intl package constrains results in version solving failer.

Bug report

Describe the bug

Description

when depending on firebase_auth and flutter_localizations in flutter project the command flutter pub get fails with this log :

flutter pub get
Resolving dependencies...
Because no versions of firebase_auth match >4.2.9 <5.0.0 and firebase_auth 4.2.9 depends on firebase_auth_web ^5.2.8, firebase_auth ^4.2.9 requires firebase_auth_web ^5.2.8.
Because firebase_auth_web 5.2.8 depends on intl ^0.17.0 and no versions of firebase_auth_web match >5.2.8 <6.0.0, firebase_auth_web ^5.2.8 requires intl ^0.17.0.
Thus, firebase_auth ^4.2.9 requires intl ^0.17.0.
And because every version of flutter_localizations from sdk depends on intl 0.18.0, firebase_auth ^4.2.9 is incompatible with flutter_localizations from sdk.
So, because example depends on both firebase_auth ^4.2.9 and flutter_localizations from sdk, version solving failed.
exit code 1

Steps to reproduce

Steps to reproduce the behavior:

1. make new project
2. add flutter_localizations & firebase_auth packages
3. run flutter pub get

Expected behavior

please check #10199 (comment) issue comment for current workaround.

There's an open PR to upgrade intl to latest version that you can track for further updates: #10443

I am closing this as a duplicate.
