How to: automatic publishing with multiple packages

[guidezpl]

https://dart.dev/tools/pub/automated-publishing mentions "multiple packages" a couple of times. But it doesn't show how to specify working-directory to support this.

Is this possible or do I have to create a separate workflow for each package?

There's an example of using automated publishing and mono-repos here:

https://github.com/google/dart-neats/blob/master/.github/workflows/publish.yml

It's a creative combo of bash and sed.

Separately, the dart team has some prescriptive tooling built on top of the pub + github automation; https://github.com/dart-lang/ecosystem/tree/main/pkgs/firehose. That's not really intended for broad use but is something we ourselves will use to publish packages. It'll detect whether it's running from a single package repo or a mono-repo; you can see an example of the integration here: https://github.com/dart-lang/shelf/blob/master/.github/workflows/publish.yaml.

Oh nice! It would be worth pointing this out in the docs

Dumped a comment in dart-lang/site-www#4574

I think it's fairly reasonable to make a workflow file per package. The thing I did in dart-neats repo is only going to work in cases where the package folder is the package name, and the tag pattern is <package>-{{version}}.

I'm open to providing better logic, but honestly, it's probably better if we just tweak mono_repo to generate workflows for publishing.
