Dart Team's Weekly Digest

Posted by Anders Sandholm

Another round of weekly updates from the Dart team:
  • Language-wise, mirror implementation and testing in flight.
  • In the VM, the new compiler pipeline compiles 90+% of all methods in frog. We support regular expressions as patterns in String methods and implemented spawnFunction in the new isolates API. First steps of adding thread pool support for isolates and native ports. Support in the Dart C API for prologue weak persistent handles.
  • In the Dart to JavaScript Compiler, we added support for concatenating adjacent string literals, made the optimizing backend capable of dealing with large code bases by being a bit smarter about how we enqueue methods we haven’t yet compiled. Finally, we’re getting ready to consolidate the frog and leg components into a single dart2js compiler.
  • We now have Dartium on Windows.
  • In the Dart Editor, we added new “SDK” entry in Files view to show dart: libraries and undo support for new Files view plus other improvements and fixes. Omnibox fixes. We updated analysis to support adjacent string literals.
  • On Dart Server, we landed support for native extensions on all platforms and we’ll write up documentation on how to write native extensions in the near future. We also added proper escaping to Windows Process arguments and added writeString method to OutputStream. Finally there is work in progress to improve error reporting from all native APIs.
  • O’Reilly published a short What is Dart? ebook.

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…

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…

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…
