I’m trying to use the following packages and the app keeps crashing

The libraries are :

  1. Fire base auth


  2. Google sign in

  3. Local auth

Solution 1: devsin

You should make firebase configuration first. You can use this codelabs: https://codelabs.developers.google.com/codelabs/flutter-firebase

Then you can add firabase_auth library to pubspec.yaml like this:

    sdk: flutter:

I recommend you go step by step and don't mess up with google sign in now. Just use email and password authentication for now.
