Alternatively, type the path manually or click the Browse button and select the path in the dialog that opens.

If WebStorm recognizes the Dart SDK correctly, its revision number is displayed in the Version read-only field.


In this read-only field, WebStorm shows the revision number of the detected Dart SDK, provided that the SDK is recognized correctly.

  • If you have already downloaded the latest SDK version, click the Dart Settings link to switch to the Dart page of the Settings dialog and specify the new SDK location.

  • Stable channel

  • Stable and Dev channels

Webdev server port

In this field, specify the port on which the webdev server will start the Dart web app , see Running and debugging Dart web applications.

If you are debugging your Dart web application with Dart webdev daemon, configure the port in the Dart Web run/debug configuration, see Running and debugging Dart web applications.

The default webdev server port is 53322. If this port is already busy, WebStorm uses the closest free one.
