BIG BREAKING CHANGE: dart.js Bootstrap File is Moving to Pub



dart.js file is moving to Pub and can be found in the new browser package. The familiar link to dart.js from your html files,
should be replaced by declaring a dependency to this package, or by hosting a local fileThis is a far reaching change that will impact all browser based Dart applications; Dartisans are urged to follow the advice provided by Vijay Menon

FYI: We are moving the bootstrap file dart.js to pub.  Please update any links to dart.js from your html files accordingly.  

We will delete the old copy of dart.js in our repository in a couple weeks.

The dart.js file is used in Dart browser apps to check for native Dart support and either (a) bootstrap Dartium or (b) load compiled JS instead.  Previously, we've recommended that you add a script tag pointing the version of dart.js in our repository.  This doesn't work offline and also results in slower startup (see dartbug.com/6723).

Instead, we now recommend that you install dart.js via the following steps:

1. Add the following to your pubspec.yaml:
  dependencies:
    browser: any

2. Run pub install.

3. Use a relative script tag in your html to the installed version:
<script src="packages/browser/dart.js"></script>
If you do not wish to use pub, you may host a copy of this file locally instead.  In this case, you will need to update it yourself as necessary.  We reserve the right to move this file in the repository, so we no longer recommend linking to it directly.
As always, we invite you to join our Dart mailing list, ask questions on Stack Overflow, or file feature requests on dartbug.com.

  1. Although this comment has nothing to do with the news that was posted...

    I think that if the dart team would offer courses on moocs, it would increase language adoption speed exponentially. It seems to me that when a language gets into academia it quickly becomes much more popular. I suggest everything from cs 101 to game programming. Thank you!

  2. Following the exact procedure outlined on this web page yields this:
    WARNING: This page is using a deprecated dart.js file. Please update this page as described here: http://news.dartlang.org/2013/01/big-breaking-change-dartjs-bootstrap-file-moving-to-pub.html
    Note the reference to this same page.

    1. Yeah, I get the exact same message too. It doesn't seem to bring in the 'browser' package into the packages directory for some reason...

    2. I think the problem is not that it doesn't bring the package in (which it does), but that it seems to think the package is not up to date for some reason. Of course using the "browser: any" should avoid the problem by always using the latest version, but evidently either the error checking doesn't work, or the latest version isn't used.

  3. Please update http://synonym.dartlang.org/ to reflect this change.

  5. I'm trying to start learning Dart by building Hello World. I've installed full Dart Editor, created a Web project with sample code (including "browser" dependency), and tried to run Pub Install. As result I've got an empty "packages" folder and pubspec.lock file. Why "browser" is not being downloaded? I have Windows XP Professional SP3. Is it supported? Where can I find supported OS list?

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…

Dart 1.12 Released, with Null-Aware Operators and more

Dart 1.12.0 is now released! It contains the new null-aware operators language feature, and enhancements to pub, Observatory, dartdoc, and much more.

Null-aware operators

The new null-aware operators help you reduce the amount of code required to work with references that are potentially null. This feature is a collection of syntactic sugar for traversing (potentially null) object calls, conditionally setting a variable, and evaluating two (potentially null) expressions.

Click or tap the red Run button below to see them in action.

??

  if null operator. `expr1 ?? expr2` evaluates to `expr1` if not `null`, otherwise `expr2`.


??=

  null-aware assignment. `v ??= expr` causes `v` to be assigned `expr` only if `v` is `null`.

x?.p

  null-aware access. `x?.p` evaluates to `x.p` if `x` is not `null`, otherwise evaluates to `null`.

x?.m()

  null-aware method invocation. `x?.m()` invokes `m` only if `x` is not `null`.

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…
