Dart is an open-source, scalable programming language, with robust libraries and runtimes, for building web, server, and mobile apps.
A new Dart Editor build is available at www.dartlang.org/editor. Changes include:
Added a new sample to the welcome page - Solar 3D! This demonstrates the use of WebGL. You can view it at Tools > Welcome Page.
Removed support for obsolete style annotations @deprecated and @override in comments.
Opening the samples from the Welcome page now creates the sample contents in user.home/dart directory.
Fixed an issue on Windows where we couldn’t launch applications with spaces in the path name..
Breaking Change List:
The asynchronous Element.rect API has been removed, in its place are the standard DOM methods (clientWidth, offsetHeight, etc).
Remove support for old style pub package layouts.
