Dart 1.5 was released last week with a focus on mobile development. This includes a version of Dartium that works on Android along with editor improvements to support debugging of mobile web apps built using Dart.
Dartium is a special build of Chromium that includes the Dart VM - it is convenient to use this to test web apps written in Dart, without having to compile it to JavaScript. Improvements in the editor, together with a Dartium build for Android, now allow you to launch and debug a Dart mobile app on an Android device. You can learn more about using these mobile-centric tools from the documentation.
Some other improvements in this release -
- Shipped two new set of polymer elements, core_elements and paper_elements
- Better version resolution, lazy transformers for Pub (Dart Package Manager)
- Editor improvements - low memory warnings and recommendations, formatter improvements, integration with Observatory (the Dart profiler)
- Several Observatory improvements
