How do I see docs/suggestions for how to use a method?

[sethladd]

I'm staring at code like this: _counter.abs() and I'm wondering "what goes into abs(), if anything?"

How do I answer that question, using Visual Code? Can I see the API docs? Can it tell me what goes in here?

Or, do I have to jump to the source to see how to use it?

Thanks!

Until #15 is implemented (which needs dart-lang/sdk#27034), the answers are a bit lame. You could either see the args in the completion list before completing, you can hover over the abs part to get a tooltip, or you could F12 into it.

I tend to use the tooltips currently (though I'm not writing much Dart - spare time tends to go on Dart, so still no real Dart work!) but this is one of my big annoyances - it's basically functionality I've not been able to provide yet :(

I've added a comment on dart-lang/sdk#27034 in the hope it might be considered sooner. If not, if I can get a chunk of spare time, I might have another go to see if there's an alternative way I can do it (I'd need to get some sort of AST, maybe the AS exposes something like that through one of the other calls) or see if I can get the SDK building on my machine in a way that I would try implement myself to send a PR (though that's a long shot, I don't know if I know enough to implement it in a way that'd get merged).

I got nowhere trying to make this work using other APIs (and I've spent many hours over several days trying) so I'm gonna mark this as a dupe of #15 and dart-lang/sdk#27034. I don't think there's a good way I can fix this until the Analzyer has support for it (though if anyone has ideas I'm open to suggestions - this is one of my biggest annoyances writing Dart!).
