BREAKING CHANGE: Renaming web_components Package to web_ui


The web_components package has a new name. John Messerly gives us the details

We're renaming the web_components package to web_ui. Aside from saving everyone's wrists a bunch of keystrokes :), this new name was chosen to reflect the growing mission for the project. When we first started, we envisioned the project as a polyfill for the new HTML5 web components standard. But since then the effort has expanded to encompass a bunch of model-driven views (MDV) and template features, data watching, CSS polyfill work (just starting), and more. Web components is one of the shiniest new features, but there are other shiny features already there and more coming.

We also have a new mailing list for the project! Please do sign up if you're interested in discussing how to build web apps on top of the exciting new standards.

Send your web-ui thoughts to: web...@dartlang.org


Here are the changes:

pub package:
rename this in your pubspec.yaml

library name:
-import 'web_components/web_components.dart';
+import 'web_ui/web_ui.dart';

github project:

compiler (unchanged):
bin/dwc.dart


I’ve uploaded a final version of web_components, with @deprecated, that depends on and exports the new web_ui package. I hope the upgrade process is relatively painless -- but don't hesitate to reach out to us if you hit any problems.

We’re still in the process of updating the documentation on dartlang.org. You can follow the progress at https://github.com/dart-lang/web-ui/issues/247.

Cheers!

As always, we invite you to join our Dart mailing list, ask questions on Stack Overflow, or file feature requests on dartbug.com.

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…

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…
