New to mobile app dev, I am attempting to follow this Firebase for Flutter tutorial:
https://codelabs.developers.google.com/codelabs/flutter-firebase/#4
Importing the firestore package per the very first line in main.dart is presumably what is causing the following result when I try to run it. Am I not following the tutorial correctly?? My code looks exactly as in the tutorial. I copied & pasted.
This is with Android Studio 3.5.3.
