"Publish" workflow analyzes .pubignored files

[osa1]

In https://github.com/google/protobuf.dart we use dart-lang/ecosystem/.github/workflows/publish.yaml workflow to perform publishing checks.

Currently this workflow fails in dart analyze step because dart analyze analyzes tests, and tests need a build step to run (make protos).

This behavior makes sense when working on the package, however when doing publication validation, we need to either

1. Run the build step make protos before dart analyze, which currently the workflow does not support

   • Note that the git repo has two packages, and we only want to do this in one of them

2. Or, make it .pubignore-aware

I feel like (2) makes sense in general as analyzing with non-published files can actually hide problems, for example if I accidentally add a file to .pubignore that's actually needed by the package.

(google/protobuf.dart#894 adds the tests to .pubignore)

Transferred as this is mainly a feature request to dart pub publish

Yeah - we need a good way to remove those files from analysis.
