 - package:quiver

This error happens because you’re trying to run your application with libraries that don’t support null safety. You can fix that by running your application with this command:

flutter run --no-sound-null-safety

In case that you’re using an IDE, you need to change the running configurations, for example in VSCode will be:

Code => Preferences => Settings => Search setting, type in "flutter test" => Dart: Flutter Test Additional Args, Add item => Add "--no-sound-null-safety

I suggest that you check this link in order to understand how to understand this error better.
