New Dart Editor Build 0.2.7.1_r15699


Dart Editor has a new build that supports theming, better error reporting, disabled support for the old getter definition syntax, numerous changes to the dart:html library and more.


Devon Carew fills us in on the details on this new build:
A new Dart Editor build is available at www.dartlang.org/editor. Changes include:

  • Added support for theming the Editor - check out the 'Visual Themes' page in the preferences dialog.
  • The extract local Variable refactoring can now extract part of a string literal.
  • Several build.dart improvements, including better error reporting.
  • There's now an option to not warn when a class with noSuchMethod() has unimplemented members.
  • Added an analyzer command line option: --type-checks-for-inferred-types. This lets command line users get the same warnings they would get with the editor.
  • Analysis changes to support the upcoming iterator changes.
  • Html editor tweaks and improvements.

Breaking changes:

We disabled support for the old getter definition syntax. The empty formal parameter list in the getter definition will be a compile error. To convert your sources from old to new syntax, simply remove the empty parameter list after the getter name. For example:

old: int get Length() => a.length;
new: int get Length => a.length;

dart:html changes:
  • Members have been ‘dartified’- they now follow the Dart naming guidelines (caveat that innerHTML has been special-cased to ease the transition to innerHtml)
    • old: Element.innerHTML
    • new: Element.innerHtml
  • Element.addText and Element.addHtml have been renamed to Element.appendText and Element.appendHtml.
  • There is now Element.append(element) as an abbreviation to Element.children.add(element).
  • pkg/htmlescape has been deleted.
                      And as always, view the changelog for the full list of changes, and to get started with the Editor see our tutorial.
                      As always, we invite you to join our Dart mailing list, ask questions on Stack Overflow, or file feature requests on dartbug.com.

                      Dart in 2016: The fastest growing programming language at Google, 2nd fastest growing in TIOBE Index

                      Dart was the fastest growing programming language at Google in 2016 with millions of lines of code written. It also made it to TIOBE Index Top 20 this month (see TIOBE's methodology).

                      It takes time to build something as ambitious as Dart and, in some ways, Dart is still in its infancy. But we're glad the hard work is starting to pay off.

                      Many thanks to our amazing community!

                      We're going to celebrate by ... releasing 1.22 next week (as per our usual 6 week release schedule).

                      The new Google AdSense user interface: built with AngularDart

                      AdSense is a free, simple way to earn money by placing ads on your website. The team just launched a completely new version of their app for publishers. Read all about it here. We asked Daniel White, the tech lead for the project, some questions because the new UI happens to be built with Dart and Angular2.


                      AdSense launched way back in 2003. How long is it since the last big redesign?
                      Last big redesign was called ‘AdSense 3’ and launched about 6 years ago. It was written in Google Web Toolkit (GWT) and the UI has evolved through several iterations - but this is the first ground-up redesign in 6 years. There are a number of long-standing UX issues that we’ve taken the opportunity to solve. A big shout-out to our UX team who’ve been 100% behind this project. We couldn’t have done it without them!

                      How many software engineers worked on the project?
                      Purely on the AdSense applications, we have a team of close to 100. Around 25% of them write Dart.

                      How many lines of code?
                      We have around 160K LO…

                      AngularDart 2.1 and new Components

                      AngularDart got its own dedicated team 5 months ago. Last month, we launched 2.0 final on the Dart Developer Summit. Today, we’re releasing the first minor release after that: 2.1.

                      Since the focus of AngularDart is Productivity, Performance, Stability, there are no major breaking changes (see the changelog) — but a lot of behind-the-scenes improvements. Your apps will get slightly smaller and faster (even relative to 2.0 which already made huge strides in size and performance since the compiled-from-TypeScript days).

                      Many features that AngularJS had to implement for JavaScript and TypeScript are not needed in Dart (because Dart already has those features out-of-the-box). So we’re removing them from AngularDart. Renderer is deprecated in favor of plain-old dart:html. NgPlural is going away — Dart programs can use the package:intl library.

                      On the Dart Developer Summit, we launched AngularDart Components — the material design widgets Google is using in customer-facing apps …
