Flutter integration_test - add --flavor argument in VS Code

I have a suite of integration tests for a Flutter app. I would like to run them using the VS Code Testing tab, so that I can easily see info about what tests passed/failed, etc.

This worked fine before we implemented flavors. Now that flavors are defined in launch.json, running the tests require a --flavor argument, but I can't seem to set that in the UI.

If I try to run them on iOS using the Testing tab in VS Code, I get this error:

The Xcode project defines schemes: dev, prod, qa Exception: You must specify a --flavor option to select one of the available schemes.

I can run flutter test integration_test --flavor dev, but the terminal fills up with logs and it's harder to find out which tests failed and why.

I just struggled with it too. You need to add this in your launch.json:

{
        "name": "integration test",
        "request": "launch",
        "type": "dart",
        // Define your flavor (here: foo) that you use in tests
        "toolArgs": [
            "--flavor",
            "foo",
        ],
        // This is important: set it only for integration_test
        "templateFor": "integration_test",
    },

Thats it! Now you can run them on VSCode too.
