[sethladd]

Tracking issue for implementing the package spec proposal.

Main issue: dart-archive/dart_enhancement_proposals#5

Marked this as blocking #23372.

I'm guessing that this is for the command-line analyzer, and that the requirement is that it support a command-line option to specify a file? (If I understood correctly, we decided that analysis server would continue to run pub and that the command-line analyzer would run pub unless a package map file is specified.)

Added this to the 1.11 milestone.
Removed Priority-Unassigned label.
Added Priority-High, Analyzer-Command labels.

For the workflow for how to find an app's dependencies, (including how to look for a packages/ dir, package spec file, package root, etc), please see the proposal and let us know if we need to refine that.

And yes, this is for the command-line analyzer.

For the record, here's the plan that I recall from the meeting:

* analyzer and analysis server will try pub's list-package-dirs first.

• if that command returns with some signal that says "there's no pubspec.lock file here", then analyzer and analysis server will try the workflow as specified by the .packages proposal
• these tools will use the package_config package

Did I get that right?

That sounds right to me!
