tests fail in github actions

[Dan-Y-Ko]

Hello, my tests pass when I run them locally (macos) but fail when run through github actions. I believe it is related to mocking network images in the tests but if not I apologize.

I have tried switching the os gh actions builds on to macos and it does succeed, so it seems to be some kind of issue with ubuntu? I'm not sure the reason for it failing in that environment.

Here's the logs:

Warning: At least one test in this suite creates an HttpClient. When
running a test suite that uses TestWidgetsFlutterBinding, all HTTP
requests will return status code 400, and no network request will
actually be made. Any test expecting a real network connection and
status code will fail.
To test code that needs an HttpClient, provide your own HttpClient
implementation to the code under test, so that your test can
consistently provide a testable response to the code under test.
