Dart Editor

For an overview, watch this short video on how to use Dart Editor.

Installing Dart Editor

Download Dart Editor, if you haven’t already.

Dart Editor requires the Java runtime. Download the JRE, if needed. Dart Editor requires JRE 6.0 or later.

The default version of Dart Editor is the stable build. It’s automatically updated about once every six weeks. The change log has a list of release dates and features.

The dev channel build, on the other hand, is the latest tested version of the Dart Editor which contains the newest features but may still contain some bugs. If you use the dev channel build, please get new builds frequently, and send feedback about new features and bugs that you encounter.

Updating Dart Editor

Dart Editor can automatically update itself, along with the SDK and Dartium, whenever a new integration build is available. To enable automatic updates, go to Preferences, choose Update, and select Download updates automatically.

If you’d rather choose when to update, make sure Download updates automatically is not selected. Then when you’re ready to update, use the About Dart Editor dialog to download and apply updates.
