How to retrieve Firebase installation auth token from Flutter?

We want to test A/B-testing with this guide, but I can't find method for retrieve installation auth token in FlutterFire plugins

I also try to implement simple Flutter plugin to retrieve token with this guide, but get stuck on iOS-part with error Specs satisfying the Firebase/Installations dependency were found, but they required a higher minimum deployment target.

Can anybody help with iOS-part? I am Android-developer, don't know Cocoapods:)
