Issue 1:
A user reports that his flutter run on the example app of the firebase_auth plugin was failing with a non-descriptive error (I didn't capture that error, sorry). Running with --verbose showed that he needed to upgrade his cocopods (see below). Running pod repo update solved the issue. Flutter should show what to do even when you run without --verbose.

Issue 2:
Hi there,

I was able to add tab controller to my Flutter project. But I do not like the swipe effect that I can swipe between different tabs. Is there a way to stop this effect?

I've tried couple ways, with or without SingleTickerProviderStateMixin. So far no luck.

Thanks a lot,
