Need a way to flag a package as most likely a dev dependency?

[kevmoo]

See google/json_serializable.dart#1280 (comment)

json_serializable almost always should be included in dev_dependencies but see https://pub.dev/packages/json_serializable/install

Wondering if it makes sense to let package authors flag their packages as (mostly) meant for dev_deps?

This is a duplicate of #3403 I'm closing it here. I'll also add a pub-dev override for package:json_serializable to put it in the dev_dependencies on the install page.

I don't really think this is a duplicate of #3403.

Giving packages a way to indicate that they are dev-tools could be relevant in more ways.

Pana could adapt its analysis (eg. a dev-tool can be used with flutter even though it uses mirrors).
There could be a search option/tag is:tool (I think we discussed that in another recent issue)

Perhaps pub global activate could somehow use this information (though that might be hard to do in a non-breaking manner).

Perhaps you could get a lint if you depend on a tool in direct dependencies (unless you yourself are a tool).
