[Change request] Holistic project support

[oravecz]

DCM version

v5.5.1

What problem do you want to solve?

DCM currently analyzes a pubspec as standalone, and doesn't consider transitive packages, especially those which are present within a packages folder in the project itself.

This results is metrics surrounding unused code/files etc. to be misleading. Any public APIs or components exposed by the package are regular used by consuming packages, not the package where it is created.

What do you think is the correct solution?

I'd like DCM to navigate packages which are not located in the pub cache, such as following a path dependency or perhaps a github dependency prior to determining if code or a file is unused.

Have you tried --monorepo flag for unused code / files plus calling the command from the packages/ folder?

[oravecz]

In my project I use a packages folder for feature development. This permits me some type of monorepo structure where different teams can be responsible for their own feature sets, but these packages are not intended on being deployed to a public (or internal) pub.dev repository. It's just an code/team-organization concept.

I would like to scan the project as a whole, and identify any widgets, extensions, or functions which are unused across the application as a whole. Not per package.

Edit: Another way of thinking about it is, I would like to know what tree shaking will remove from my project.

So that's exactly what I'm suggesting you to do: if you run check-unused-code packages/ --monorepo it should give you exactly what you're looking for.
