Bootstrap Widgets Ported to Web Components with Dart Web UI

The wildly successful Bootstrap project, which helps web developers build responsive designs for web apps, has been ported to Dart's Web UI library. This means the dynamic widgets like accordion, carousel, tabs, and more, are reborn as actual web components. The Dart Widgets library has all the code, and you can easily install it from pub.

With real encapsulation, you can now use custom components that contain the structure, style, and behavior of the widget. For example, instead of using div elements with special classes and requiring another script to make it all work, you can simply use <x-accordion> which contains everything you need.

Here is an example:

    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse">Item 1</a>
    <p>Item 1 content - Lorem ipsum</p>
    <div class="accordion-heading">
      <a class="accordion-toggle" data-toggle="collapse">Item 2</a>
    <p>Item 2 content - Ut enim ad minim </p>

Thanks to Kevin Moore for open sourcing this project. Get started building declarative modern apps with Widgets and Web UI today!


  1. This looks nice Seth! Are you planning a Video Podcast showcasing the new Dart bootstrap widgets and bootstrap grid etc?

  2. Hey Seth,

    I don't know much about responsive design and what it entails, but I do know that Bootstrap supports some responsive design "stuff". Is it just a matter of including something like Twitter Bootstrap CSS files and designing your site's HTML so that it's responsive or is there more to it than that? In other words, more JS (or Dart in our case)?

Const, Static, Final, Oh my!

Posted by Seth Ladd

(This is an "oldie but a goodie" 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 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…
