For instructions on installing the Dart or Flutter extensions, go here.
v3.142.0 2026-09-01
Flutter
- #6054: With the recent stable release of Flutter, the “Add a name to the constructor” and “Add a prefix to the import” refactors now prompt for a name rather than inserting a server-generated name.
- #6134/#6140: Deep-links into DevTools (such as into the Widget Inspector when Overflow errors occur) are once again supported. When such an error occurs, a toast notification will offer a button to open a DevTools page an jump to the correct widget/location.
Debugging
- #6133: The “Starting debug session…” text no longer appears for much longer than intended when running tests that produce no output.
Misc
- #6141: A previous workaround to avoid issues when Flutter called
gitcaused by the Copilot extension mutating environment variables has been removed, since the Copilot extension shipped a fix back in June. - #6110: Due to Firebase Studio being sunset, support has been removed.
Fixes enabled with Future VS Code releases
#6155: Errors like “Quick Fix failure: _dart.applySnippetTextEdit command not found” when using quick-fixes and code actions have been resolved in the upcoming v1.136.0 release of the VS Code editor (not the Dart extension).
Features/Fixes Enabled with Future SDKs
The following items depend on changes to the Dart/Flutter SDKs that have not yet been released to stable channels. They may be available to test in the current beta/master channels and will show up in future SDK releases.
#6092/#6108: Refactors that use the new input framework (such as “Add a name to the constructor” and “Add a prefix to the import”) will now perform validation during typing instead of waiting for submission. Errors will suppress submission whereas warnings do not.
- sdk#64030: The “Fix All in Workspace” commands now include the same Pubspec fixes as
dart fix(for example adding missing dependencies). - sdk#64029: The “Fix All in Workspace” commands are now iterative and make multiple rounds of fixes, just like the single-file “Fix All” command/code action.
- #6143: The color preview/picker has been updated to detect the
withValues,withAlpha,withRed,withGreen,withBluemethods onColorinstead of just showing the base color prior to the invocation. - #6142: The new dartdoc example format
{@example ...}now produces clickable links, like the previous “See code in …” format that was used in the Flutter SDK. - PR : Add support for client-side regex validators in interactive forms.
- #2391: “Add to watch” and debug console evaluation now support multiline expressions, instead of only evaluating the first line.
