Dart-code: VSCode, Flutter, Code Completion - Bracket Problem.

Are you using the LSP Preview? If so, this was only added recently and needs to be enabled with the dart.completeFunctionCalls setting. There's some info about this in the release notes here:

https://dartcode.org/releases/v3-17/#lsp-complete-function-calls

Please let me know if this doesn't solve the issue!

Hi,
Thanks for helping.
Recently I have the same issue, which is auto-complete doesn't work in vs code.
When I type a function like List.generate the parameters placeholder used to show, but now it doesn't show.

I have dart.completeFunctionCalls enabled and dart.enableCompletionCommitCharacters disabled

Flutter: 1.22.1-0.0.pre.1
VS Code Version: 1.52.1
Flutter Extension Version: 3.18.0
Dart Extension Version: 3.18.0
OS: macOS Catalina 10.15.4

Hi again,
Problem was in my settings.json.
I edited file like this. Now everything is fine.
{ "dart.completeFunctionCalls": true, "dart.enableCompletionCommitCharacters": false, "editor.formatOnSave": true, }
