Autocomplete not inserting parentheses or arguments for some items

See original GitHub issue

Describe the bug Autocomplete seems to be working for some items, not for others.

So far I have tested these:

Working	Not working
Custom functions	print
.forEach	widgets

So this is working as expected for something like a function I wrote myself, or myList.forEach(). Not sure why others aren’t working.

To Reproduce Steps to reproduce the behavior:

In a function, eg main(), type prin
Press Tab to accept ‘Print’ autocomplete

Expected behavior The item, eg print() or Text() should be completed with parentheses and arguments if appropriate.

I guess it is a related issue that parenthesis are not added for example to ChangeNotifier.notifyListeners()?

If you’re on the Flutter stable channel, it seems likely. Support for dart.completeFunctionCalls is not yet available in Flutter’s stable channel.

So this will be fixed too by dart-lang/sdk@2f2f9fc?

I just tested it on a recent Flutter master and I’m getting parens accepting notifyListeners with dart.completeFunctionCalls enabled, so I believe it’s either fix by that change (or the previous one that first added the functionality).

are there any workarounds?

You could either switch back from LSP, or use a different Flutter channel. Unfortunately I don’t believe there are any other workarounds. The LSP functionality is not complete in current Flutter stable (this is the reason it’s still behind the preview flag). LSP won’t be made default until after these fixes all make the Flutter stable channel, though I’d encourage using LSP if there’s nothing breaking to you to help identify any remaining issues/gaps. If this is sufficiently annoying, I would recommend switching back.
