• For some reason the widget guides feature is not available.
• Tests codeLens(Run|Debug) is not available.

@DanTup I'm implementing the Emacs support for dart/flutter on lsp-dart so I'm checking how you did it on this extension and notice the problems above :)

[DanTup]

@ericdallo thanks! I've added UI Guides to the list above. CodeLens is supposed to work, though I can see it failing so I've opened #2421 - probably will be an easy fix. Thanks!

[ericdallo]

I implemented the both features on lsp-dart, so I think it's easy to fix them on the vscode extension :)

[DanTup]

@ericdallo actually, the reason my code lens didn't work is that I was using an older Dart SDK that wasn't sending the outline notifications. On the most recent nightly the code lens seem to work fine. Do you know what version you were using when you saw it fail?

[ericdallo]

Yeah, me too 😅 I was using dart dev 2.8.0-10

[DanTup]

Ok great, working as expected then :-) I've fixed up Flutter UI Guides and Gutter icons too.

[ericdallo]

Nice! just a thing to keep in mind, If the next features could be implemented for LSP too, I could implement it on lsp-dart :)
Thanks!

[DanTup]

@ericdallo do you mean specific features, or just in general? Any new features being implemented are very likely to be added to LSP too (some may even only be implemented in LSP) as I'd like to switch Dart-Code over to LSP by default (without losing any significant functionality).

Some of the things mentioned above (like dart.analysisExcludedFolders and dart.doNotFormat) are kinda hacks though, so they might not be carried over (or may be reworked if they are).

[ericdallo]

Nice, good to know!
That's what I wanted to hear, I was afraid that DAS was the focus for new features, not LSP
