New Dart Editor Build 0.2.6.0_r15355


Dart Editor has a new build and it incorporates many of the changes that have been announced on these pages recently.  The change list includes modifications to the core library, as well as the html, SVG and io libraries. 

most SVG types no longer need the SVG prefix; SVGElement is now Element


Eric Clayberg fills us in on the details on the new Dart Editor build:
A new Dart Editor build is available at www.dartlang.org/editor. Changes include:
  • New Clean-Up to rename Element.elements to Element.children.
  • New Clean-Up to remove return type and name in function literal.
  • New "Convert Getter to Method" refactoring and Quick Assist action.
  • New Clean-Up to rename File.readAsText to File.readAsString.
  • New "Surround With..." Quick Assist.
  • UX changes and improvements in the Manage Launches dialog.
Breaking Change List:

      • dart:core changes
        • Exception constructor is no longer const, and usage is discouraged.
        • NullPointerException has been removed. Throwing null now throws NullThrownError. Accessing non-existing members on null throws NoSuchMethodError (Null just inherits noSuchMethod from Object).
      • dart:html changes
        • Element.elements has been deprecated in favor of Element.children.
      • dart:svg changes
        • Most SVG types will have their prefixes removed. So SVGFontElement will become FontElement. This does introduce some overlap with dart:html names, it’s recommend using "import 'dart:svg' as svg;" if you're mixing dart:html and SVG.
        • All dart:svg names will be 'Dartified' to have proper camel-casing. SVGFEDropShadowElement is now FEDropShadowElement.
        • SVGDocument, SVGElement and SVGSVGElement unfortunately will not immediately have their prefixes renamed as they require a much more significant refactoring to do so. They have been camel-cased though (to SvgElement, SvgSvgElement, etc).
      • dart:io changes
        • dart:io File.readAsText renamed to File.readAsString and File.readAsTextSync renamed to File.readAsStringSync.
