Towards a single Dart to JavaScript compiler


Posted by Kasper Lund

As some of you have already noticed, we've started making it easier to use our new Dart-to-JavaScript compiler backend implemented in Dart ("frog") from within the Dart Editor. This is the first step towards
replacing our first generation backend with a new shiny and improved implementation. We expect to complete the transition within a few weeks after which we'll be back to having only one way of compiling
Dart to JavaScript.

The new Dart-to-JavaScript compiler backend uses tree shaking to cut down on the generated code size and we're working on using an SSA-based intermediate representation to allow us to use classical
optimizations such as local type inferencing, loop-invariant code motion, and function inlining. The compiler runs on top of the Dart VM and makes use of the new server-side libraries such as dart:io. It is really nice to see things coming together this way!

As always your feedback on what works well and what doesn't is really important to us, so I hope you'll continue to file bugs and speak your mind on our mailing lists.

  1. How are you going to integrate Dart in GWT?
    It would be nice to be able to develop in GWT using a Dart VM for fast compiling and debugging. Finally, distribute the application using the javascript compiler so non-Chrome browsers can also execute the application.

  2. @Otamuka brilliant question/proposal!

    Can you guys provide more info for GWT devs of how GWT will be integrated into Dart resp. vice versa? There are many GWT devs who see Dart as the next-gen GWT ...once there is a component framework for Dart like GWT's UiBinder.

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…
