v3.140.0 2026-08-03

Flutter

• #5844/#4607/#6109: Flutter SDKs from PATH now take priority over those found only from a .dart_tool/package_config.json file. Use the dart.flutterSdkPath setting if you want to set an explicit SDK path that differs to what’s on PATH.

Editor

• #6130/#6132: The TextMate grammar used to provide initial syntax highlighting until the server provides Semantic Tokens has been updated to handle unclosed triple-backtick code blocks in dartdoc comments.
• #6120/#6121: Code actions that make multiline replacements will no longer sometimes end up with additional indentation.
• #6118/#6135: A new command Dart: Toggle Show TODOs toggles the dart.showTodos setting, allowing TODOs to be quickly shown or hidden.

Testing

• #5967: When using package:test_reflective_loader, class-wide setUp/tearDown methods no longer appear on all classes, whether they exist or not (requires an upcoming release of package:test_reflective_loader).
• #5950: When using package:test_reflective_loader, class-wide setUp/tearDown methods in the test explorer now navigate to those methods instead of the defineReflectiveSuite call (requires an upcoming release of package:test_reflective_loader).

Commands

• #6122/#6123: The Dart: New Project and Flutter: New Project commands have been renamed to Dart: Create New Project and Flutter: Create New Project so that they are included in the results when searching the command palette for dart create and flutter create.

Misc

• #6111: Due to the sunsetting of Firebase Studio, support for using the extension on Firebase Studio is deprecated and will be removed in an upcoming extension release.
• #6117: A clearer error notification is now shown when the Dart anlaysis server fails to start due to the current version of macOS being unsupported.
• #6131: Automated tests for the TextMate grammar in the Dart-Code repository and the dart-syntax-highlight repository are now aligned and produce the same output for the same grammar/input.
• #6129: TextMate grammar tests now run on the GitHub bots.

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.

• #6054/#6059/#6077/#6107/#6098: A new mechanism has been added to allow refactors to collect user input. The first refactors to use this are “Add a name to the constructor” and “Add a prefix to the import” which will now prompt for the name rather than using a server-generated default name.
• #5066/#6082: The “Move to File” refactor has been updated to use an improve file picker to avoid misleading overwrite prompts.
• #6115: The analysis server no longer sometimes crashes if it’s open while the Dart SDK is overwritten (for example by a Flutter update).
• #6112: Code blocks in dartdocs no longer lose their colouring when the TextMate grammar is replaced by server-provided Semantic Tokens.
• #6017: The Flutter Widget Preview show no longer show an infinite loading status when it has fatally errored.
• #5839: test() and group() calls now show closing labels next to their closing parentheses.

Upstream Issues

Some feature requests and fixes require new features and fixes in upstream projects like VS Code and LSP which use counts of 👍s on those issues to help gauge demand. The Dart-Code website now lists some of the most significant upstream issues with a description of the feature/fix they would enable.
