How can use Firebase Plugins in IOS Share Extensions with Flutter view?

[thaidmfinnick]

I am using IOS Share Extensions follow this guideline: https://docs.flutter.dev/platform-integration/ios/app-extensions

About UI it works great, but I wonder how can share Firebase plugins configuration between extension and main app. For example, I am logged in using FirebaseAuth in main app, if I open Share Extension, I will be logged in too. I have not found a official documentation about this (between main app and extension).

Does anyone meet these cases? And can we achieve that?

Thank you!
