Settings

There are a number of settings for the Dart and Flutter extensions that can be modified in VS Code’s User Settings or Workspace Settings.

The settings described here are documented by their JSON keys, though most of them can also be edited in the settings UI in VS Code by clicking the Dart & Flutter section under Extensions.

Default: true.
Whether to insert argument placeholders during code completions. This feature is automatically disabled when enableCompletionCommitCharacters is enabled.

dart.lineLength

Default: 80.
The maximum length of a line of code. This is used by the document formatter. If you change this value, you may wish to update editor.rulers (which draws vertical lines in the editor) in the ["dart"] section of your settings to match.

If blank (or not a valid SDK), Dart Code will attempt to find it from the project directory, FLUTTER_ROOT environment variable and the PATH environment variable. Use ~ to insert the user’s home directory (the path should then use / separators even on Windows).

dart.flutterSdkPaths

An array of paths that either directly point to a Flutter SDK or the parent directory of multiple Flutter SDKs that can be used for fast SDK switching.

dart.getFlutterSdkCommand

Get the Flutter SDK path from a command. Useful when using tools such as direnv, asdf, mise… The command should exit with a 0 status code and it should print to the standard output just the path to the SDK.

dart.extensionLogFile

The path to a low-traffic log file for basic extension and editor issues. Use ${workspaceName} to insert the name of the current workspace in the file path.

For more information on capturing these logs, see Extension Logging.
