It's easy to get started. After you install Homebrew, run these commands to install the stable channel Dart SDK and Dartium:
brew tap dart-lang/dart
brew install dart
brew install dartium # if you build Dart client apps
When there is a new build of the SDK or Dartium, run these commands to stay up to date:
brew upgrade dart
brew upgrade dartium
Use Homebrew if you build server-side Dart apps, or you are not using Dart Editor (for example, if you use WebStorm or Sublime). To download Dart Editor, you can continue to use the download page.
We hope our support for Homebrew makes it easy for our Mac developers to stay on the latest versions of the Dart SDK. Thanks to the Homebrew developers for answering our questions along the way. We look forward to your feedback.
