Google has released beta versions of its Software Development Kit and Editor for its Dart programming language. "The Editor's analysis engine, responsible for reporting warnings and errors, is completely rewritten, and is 20 percent faster at parsing and analyzing," blogged Google's Dan Rubel. "Now, there's no need to run all the unit tests just to discover a typo. The Dart Editor watches your back as you type."
Other new features include "Rename Library" refactoring, "Convert Method to Getter" and "Convert Getter to Method" refactorings, "Import Library" quick fixes, and "Create Class" and "Create part" quick fixes, as well as improved code completion.
