The Dart Editor now supports "Quick Assists", which are small refactorings, allowing you to perform short transformations of source code. These quick fixes can save you several tedious manual operations.
For example, the Quick Assist "Split && Condition" is used when you find out that you need to do something just on the first part of && condition and you need to move second part of condition into separate "if" statement.
Try a Quick Assist by using the Ctrl/Cmd+1 hotkey.
Please let us know what other Quick Assists and refactorings you'd like to see appear in the Dart Editor by filing feature requests at http://dartbug.com/new.
