Additional context

This is my first time trying to set up Revenuecat.

I run on a macbook pro on a iphone 7 device.

I did a flutter build . which upgraded the project with some settings.
I also upgraded to minimum iOS version 12 as recommended, deleted ios/Flutter/Flutter.framework and then reinstalled using flutter pub get and did a manual pod install in the ios folder.

I build and run ok now.
