Describe the bug Dart code unable to find the tests for a newly generated Flutter project

To Reproduce Steps to reproduce the behavior:

Create a new Flutter project via flutter create your_example. Open the folder via code Select the generated test and right-mouse click on widget_test.dart and select Run Tests.

-> Message that no tests is found (see below for screenshot).

Expected behavior

Test found and run. That is was what happened in the past, AFAICS this "test not found" is something new.

This menu entry is new from VS Code (apparently I requested it 😄 https://github.com/microsoft/vscode/issues/162728), but I guess we're not handling the kind of request it gives properly.

Our menu entries are these ones:

Those still seem to work in my testing. I'll investigate why the new VS Code one does not.

Thanks @DanTup

Seems like there may be multiple issues here. The first is that VS Code doesn't trigger test discovery when opening this (I've opened https://github.com/microsoft/vscode/issues/212342), but even with that, it seems to only work on the folder and not the file in my testing - there's probably Dart-Code bugs here too.

The second issue above was also a VS Code issue - that's been fixed in latest code (verified in Insiders) via https://github.com/microsoft/vscode/issues/211338.
