No coverage data found with Flutter test

1

I’m using this action with the coverage generated by Flutter’s test. Running flutter test --coverage will create a file under ./coverage/lcov.info
In my ci.yaml file I have this

    - name: Upload coverage to Codecov
        uses: codecov/codecov-action@v1
        with:
          token: ${{ secrets.CODECOV_TOKEN }}
          file: ./coverage/lcov.info

But I get this output

Run codecov/codecov-action@v1
/bin/bash codecov.sh -Q github-action -f ./coverage/lcov.info -n  -F

What I’m doing wrong?

Hmmm… can you add a step beforehand that just does cat ./coverage/lcov.info to ensure it’s there @Supercaly? What happens if you don’t specify the file?
