Im getting the following error after updating flutter to latest version on stable branch. This error occurs when building doing flutter pub get.

The issue seems to be with localizations.

The project used to run before update.

Thanks

This is actually the same as #116459, which was fixed upstream in #116622. I will file a cherrypick request for this.
