Show type hierarchy in-line with new Dart Editor

A new Dart Editor build is available at www.dartlang.org/editor. Changes include:
  • We now support showing an in-line type hierarchy view (Command-T on the Mac and Ctrl-T for Linux and Windows).



  • We have a new Quick Fix to import or create a type when it is used as invocation target.
  • General work to the Eclipse plugins including:
    • cleaning up some spurious menu contributions,
    • adding menu items to invoke dart2js and dartdoc
    • and adding the ability to open Dart files in non-Dart projects
  • Several code completion enhancements, including:
    • support for both named and optional parameters
    • showing proposals for function parameter names following unary-?
    • improved proposals for cascades
  • Web components support is now enabled on Dartium launches by default.
  • The .project metadata file has been moved out of the user's source directory.
  • The html and css editors now use a default indent of two spaces.
  • 6 analysis fixes, as well as fixes to the debugger, Outline view, feedback dialog, auto-update, and our analyze-as-you-type feature.
And as always, view the changelog for the full list of changes, and to get started with the Editor see our tutorial.

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.

New components

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