[Bug] Quick Fix failure: _dart.applySnippetTextEdit command not found #6155
Description
Steps to reproduce
When trying to use the Quick Fix menu (Refactor action) to wrap a widget (e.g., Wrap with SizedBox) in Flutter, an error toast appears:
Actual command not found, wanted to execute _dart.applySnippetTextEdit /5044
- Open a Flutter/Dart project in VS Code / Cursor.
- Select or put the cursor on a widget (e.g., ElevatedButton).
- Press Cmd + . (or Ctrl + .) to open the Quick Fix / Refactor menu
- Click on Wrap with SizedBox (or any other wrap option).
- The error notification pops up and the text edit is not applied.
Expected results
The selected widget should be wrapped with SizedBox automatically without errors.
Actual results
An error toast pops up with the message:
Actual command not found, wanted to execute _dart.applySnippetTextEdit /5044
The widget is not wrapped, and no code changes are applied.

I was able to reproduce the second error (
logAction), which I think might be a race with startup. However I've not managed to reproduce the first error (whenapplySnippetTextEditfails).Can you confirm which version of the Dart extension you have installed in VS Code, and whether you can reproduce this:
Thanks!

This might be a VS Code issue, I see it was also reported by other extensions at microsoft/vscode#331834

Dart extension version: 3.140.0
Flutter extension version: 3.140.0
Vscode version: 1.134.0

Thanks! I'm pretty certain now that this is a VS Code issue (it appears to stash the commands in a cache, but then disposes that cache too quickly). I'll keep this open until there has been a response on that issue. confirming (or a fix) just in case there's something we need to do though.

This was indeed a VS Code bug and has been fixed for the upcoming v1.136.0 release of VS Code (see microsoft/vscode#331834).
