WebStorm 9 released with improved Dart support

Today, JetBrains announced WebStorm 9, an update to their powerful web development editor. Highlights for the Dart developer include: pub serve support, improved isolates debugging, Observatory support, new syntax support, and more.

WebStorm 9 now launches pub serve, Dart's development server, when the developer runs a Dart web app. Pub serve takes care of generating assets, compiling to JavaScript, and more.

Developing and debugging apps that run multiple computations in parallel is now easier, thanks to the new ability to set breakpoints inside of isolates.



For deep insight into your app running on the Dart VM, you can now open the Observatory directly from WebStorm 9. Use the Observatory to learn how memory is used, where CPU time is spent, and more.



It's now easier to debug apps that use collections (which is every app), thanks to the debugger's logical view of maps and lists. Developers now see the logical data structure instead of internal implementation details.



WebStorm 9 now understands syntax for deferred loading and symbols. Deferred loading helps web apps start quickly, by delaying when libraries are loaded. Symbols are used when an identifier needs to remain unmodified after minification.

We encourage you to try WebStorm or IntelliJ IDEA for your Dart development, and we hope you enjoy these new features. We look forward to your feedback.

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!

(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…
