doc: how to use multiple flags

[blueyed]

The README/doc should have an example how to use multiple flags.
(I've guessed them to be a string separated by "," (commata), as with the codecov-bash uploader itself, but it would be good to clarify)

codecov-action/action.yml

Line 15 in 66879ff

description: 'Flag upload to group coverage metrics (e.g. unittests | integration | ui,chrome)'

has examples.

Good point! I've added instructions for how to specify multiple flags in this commit

It's still not clear how multiple flags will get associated with multiple reports. E.g.:

- name: Code coverage (via codecov.io)
      if: matrix.api-level == 29 # Only upload coverage from API 29
      uses: codecov/codecov-action@v2
      with:
        files: engine/build/reports/coverage/debug/report.xml, datacapture/build/reports/coverage/debug/report.xml, datacapturegallery/build/reports/coverage/debug/report.xml
        flags: engine, datacapture, datacapturegallery
        fail_ci_if_error: true
        verbose: true

Generates the following:

/Users/runner/work/_actions/codecov/codecov-action/v2/dist/codecov -n  -Q github-action-2.1.0 -Z -f engine/build/reports/coverage/debug/report.xml -f  datacapture/build/reports/coverage/debug/report.xml -f  datacapturegallery/build/reports/coverage/debug/report.xml -F engine -F  datacapture -F  datacapturegallery -C <redacted> -v

I don't think this is correct.

There should be a way to configure a monorepo with multiple projects / modules, one for each flag.

To clarify, I have the coverage reports generated for each module in a single step. There should be a way to pick each report and associate with a flag each.

Currently is seems it is only possible via hacks like this: https://stackoverflow.com/questions/66561281/optimal-usage-of-codecov-in-a-monorepo-context-with-separate-flags-for-each-pack
