v3.118.0 2025-09-01

Deprecation of SDKs prior to Dart 3.1 / Flutter 3.13

#5667: Support for SDKs prior to Dart 3.1 and Flutter 3.13 is being deprecated. If you are using affected versions you will be shown a one-time warning advising you to upgrade.

These SDKs will still work with this version (v3.118) but some functionality will stop working with the next release. A table showing which extension versions support which SDKs (and instructions on how to change extension version) is available on the SDK Compatibility page if you need to continue to use unsupported SDKs.

Flutter

#5623/#5631: Code coverage now includes dependencies that exist in the workspace, not only the app being tested.
#5673: Enabling a new device for Flutter apps now correctly selects the launch project when the active launch configuration references a different project to the active file.
#5651/#5653: A new setting dart.useFlutterDev allows use of flutter-dev instead of flutter. This script is intended for use by contributors to the flutter tool to avoid having to manually rebuild the tool when making local changes.

AI

#5639: A new setting dart.mcpServerTools allows excluding some of the Dart MCP servers tools from registration with VS Code/Copilot. By default the runTests tool is excluded because it overlaps with an equivalent tool provided by VS Code.

DevTools

#5675: DevTools no longer opens in external tabs in Firebase Studio when set to load embedded / in the sidebar.

Testing

#5630: A new setting dart.coverageExcludePatterns allows excluding coverage from files/folders using globs. For example you could exclude **/generated/** or **/*.g.dart.
#5654: Starting an integration test will now show a progress notification while the app build is in-progress, which will be hidden once the test begins and produces some output to the debug console.

Commands

#5665: The Dart: Add Dependency command now supports space separators in addition to commas.

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.

#5599: Go-to-Definition / ctrl/cmd+click on keywords like return, break, continue will now jump to the related function/statement.
#4844: When the text cursor is on a keyword like return, break, continue, other exit points of the same function/statement will be highlighted.

#5649/#5650: An experimental flag experimentalFlutterWidgetPreview enables an early preview of the Flutter Widget Previewer which can be shown in the sidebar or an editor tab using the dart.experimentalFlutterWidgetPreviewLocation setting. Unlike the command-line version of the previewer, embedding in VS Code requires a Flutter version >=3.36.0-1 (currently the master channel). Feedback about the previewer itself should be posted to https://github.com/flutter/flutter and feedback on the integration with VS Code to https://github.com/Dart-Code/Dart-Code.

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.
