[Dart] Update the pub inspector to look up the directory structure to support the Dart Analysis workspaces feature

[jwren]

See workspaces information here: dart-lang/sdk#53875 & https://medium.com/dartlang/dart-3-5-6ca36259fa2f

@jwren Thanks for the PR. Is this document the single source of truth or there are other sources of information about how it works?

[WIP]

So should I apply it as is or wait for updates?

BTW, do you think it's important for the Dart plugin to look into the pubspec.yaml file contents and have different logic depending on the resolution and workspace tags presence?

Are there other features in the Dart plugin that should be aware of the workspaces feature?

For example, should we keep showing the bar with Pub Get/Pub Upgrade/Pub Outdated actions in the pubspec.yaml files with the resolution tag?

Thanks @alexander-doroshko.

Yes, I believe so.

I added some comments, yes, land it and push it to older IDEA platform versions if possible. I am still able to push updated Flutter IJ versions to 2023.3, but 2024.1 and forward is sufficient.

I think it is fine as-is, while we could possibly not go up a directory speeding up the check, I'd rather not be in parsing the yaml files, the fewer number of checks (existence of files) is deep enough in the weeds of what pub is doing.

Possibly, something like this would be a reason to read and parse the yaml files.

I will take and action item to see if we are missing anything, need to add anything, etc. (But lets not wait on landing this in the mean-time.)

Merged, thanks
