Dart Sessions at Google I/O 2013

Join us at Google I/O 2013 in San Francisco's Moscone Center from May 15 through 17.



This year's conference features numerous events of interest to the Dart community. You can see three Dart presentations, and take part in a Dart code lab. One of the talks, by Dart creators Lars Bak and Kasper Lund, will be streamed live. And all of the talks will be available on video.

If you are at I/O, be sure to stop by at the Dart booth in the Developer Sandbox on the 3rd floor of Moscone Center. You can ask questions of Dart team members who will be available on all three days at the booth, and also at the office hours area nearby.

Here are some details about the talks and the code lab:

Web Languages and VMs: Fast Code is Always in Fashion

Lars Bak, Kasper Lund

A fundamental necessity for innovation within web apps is fast execution speed. This talk will take a deep dive into the machine rooms of both V8 and the Dart VM and explain some of the reasons why a new execution engine is needed for taking the web platform to the next level. Please join us to hear about how programming languages impact the underlying virtual machines, complexity, on-the-fly code generation, and predictable performance.

AngularDart 4

AngularDart v4 is now available. We've been busy since the release angular2 v3.1.0 in May. Not only did we "drop the 2", but we also improved the compiler and tightened up the framework to give you smaller code, we updated the package structure to improve usability, and we added several new features. Check out the updated documentation to get started.
Just angular Upgrading to v4 will require more than updating your version constraint. The package has changed names (back) to angular – dropping the 2. You'll need to update your pubspec.yaml and the corresponding imports in your code. In most instances, find-and-replace should do the trick. Going forward, the package will be called package:angular. We'll just update the version number.
Smaller code The updated compiler in 4.0 allows type-based optimizations that not only improve runtime performance but generate better code because we are able to strongly type templates. A big result of the update is that many ap…

The new AdWords UI uses Dart — we asked why

Google just announced a re-designed AdWords experience. In case you’re not familiar with AdWords: businesses use it to advertise on google.com and partner websites. Advertising makes up majority of Google’s revenue, so when Google decides to completely redo the customer-facing front end to it, it’s a big deal. The Dart team is proud to say that this new front end is built with Dart and Angular 2. Whenever you asked us whether Google is ‘even using Dart for anything,’ this is what we had in mind but couldn’t say aloud. Until now. We asked Joshy Joseph, the primary technical lead on the project, some questions. Joshy is focusing on things like infrastructure, application latency and development velocity, so he’s the right person to ask about Dart.Q: What exactly did we launch on Monday?It’s a complete redesign of the AdWords customer experience that is rolling out slowly as a test to a small initial set of advertisers. The most noticeable thing is probably the Material Design look and f…

Const, Static, Final, Oh my!

Posted by Seth Ladd

(This is an "oldie but a goodie" misc@dartlang.org post originally written by Bob Nystrom. It is being posted here as the explanations still ring true.)

Bob writes:


"static", "final", and "const" mean entirely distinct things in Dart:

"static" means a member is available on the class itself instead of on instances of the class. That's all it means, and it isn't used for anything else. static modifies *members*.

"final" means single-assignment: a final variable or field *must* have an initializer. Once assigned a value, a final variable's value cannot be changed. final modifies *variables*.

"const" has a meaning that's a bit more complex and subtle in Dart. const modifies *values*. You can use it when creating collections, like const [1, 2, 3], and when constructing objects (instead of new) like const Point(2, 3). Here, const means that the object's entire deep state can be determ…
