Dart Editor

An open-source tool for editing, debugging, and running Dart applications.

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.

Configuring Dart Editor

Want to use the command-line tools, as well? You already have them, thanks to the Dart download including the SDK. However, you might want to set environment variables, as described in the SDK page.

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.


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.

Using Dart Editor

To get started with Dart Editor, read these:

  • Get Started (the first tutorial in the Dart Tutorials)
    Gently introduces you to Dart Editor, from downloading it to creating and running apps.
  • Up and Running (a section from Chapter 1 of Dart Up and Running)
    Quickly leads you through downloading Dart Editor, running a sample, and creating an app.

For details on using Dart Editor, read this:

  • Dart Editor (a section from Chapter 4 of Dart Up and Running)
    Teaches how to use Dart Editor — for example, how to set up launches for different browsers.


Dart Editor, with its static analysis engine and direct integration with Dartium, helps you develop, debug, and maintain your apps.

Customizing the build

You can add behavior to the Dart Editor build process by creating a build.dart file. For example, Web UI uses a build.dart file to run custom tools over Dart and HTML files and to map from the original files to the generated files. See Build.dart and the Dart Editor Build System for details on implementing your own build.dart file.
