Test runs from command line but errors when run via androidStudio

I'm just starting to learn flutter.

Here is a repo of something I just started - so not a lot to see

https://github.com/sketchbuch/lonewolf

I have one test, and if I run

flutter test

it runs and passes.

If I just right click on the file and run the test (which I see in lots of tutorials) an error occurs and the test doesn't run. Here is the error

Since the test runs via the command line I sure the problem is with how AS is configured. Can anyone tell me what exactly is wrong and how I can run a test just by selecting run in AS? I don't want to always run every test (which I think the commandline would do)
