Dart News & Updates

Videos from last month’s Dart Developer Summit are up on YouTube  and we thought we’d cherry-pick the highlights for you. The summit keynote  is a summary of all the major news and of the direction the team is taking now. It’s where we announced that Dart is the fastest growing language at Google. Teams switching to Dart report up to twice the productivity and development speed of what they had previously. Next, AngularDart 2.0  was launched in a presentation  by Ferhat Buyukkokten and Matan Lurey. They showed how they made the framework’s output 40% smaller and 15% faster in the 4 months since AngularDart got its own dedicated team . They also showed our 60 fps table using setState(), and the new testing framework called NgTestBed. Later in the day, Ted Sander launched AngularDart Components  — the material design widgets Google is using in customer-facing apps like AdWords and AdSense. Hundreds of Google engineers work with these components ever...

Developers frequently ask me if Dart is ready for the real world. Well, of course, that depends on the application. Check out this short video in which Joe Fernandez and I not only show that Dart can be used in the real world, we also show that it can be used to take the tedium out of watering your lawn! The Dart code for Lawnville was originally written in January of 2012, a mere three months after Dart was launched as a "technology preview". That was six months before Dart's M1 release, so it's been updated a few times along the way. However, the code really hasn't fundamentally changed that much since the beginning. Perhaps the most interesting piece of code is the use of a Queue (from the dart:collection library) to schedule watering tasks. You can click on different parts of the lawn, and the droid will fly over and water each section for a short amount of time: _actionQueue = new Queue(); ... _actionQueue.add({'action': 'water...

In this episode of Dartisans , I'm going to show you a variety of ways to use Dart with Google Web Toolkit. I know that there are a lot of GWT developers out there who would like to give Dart a shot, but they aren't sure how because they already have a large, successful app that's written in GWT. I'm going to show you ways to integrate Dart into your existing GWT application without having to rewrite it from scratch. To do this, I've built a sample application that uses both GWT and Dart. I'll show you how to setup a development environment so that you can work with both technologies. Then, I'll show you a variety of ways in which you can get GWT and Dart to interoperate, such as: Using GWT and Dart to manage different parts of the same page Using Dart to retrieve JSON from a Java servlet Using window.postMessage and JSNI to pass messages between GWT and Dart Using JavaScript, JSNI, and Dart's js package for synchronous interoperability between ...

The Dart Team, in partnership with Marakana, launched "Dart Tips", a new series of quick video tutorials and introductions to the Dart language and libraries . Each episode in this series is approximately 5 minutes long, so you can watch them anytime. There are six episodes now, with more planned. Seth Ladd, Dart developer advocate, tells us more: "These short videos have very specific topics, which means it's easy to find examples and explanations for exactly the right topic you are searching for. Plus, as a bonus, we've published the full transcript below each video, for the times you want to read instead of watch." Some topics include built-in types like strings and booleans, runtime modes, functions, and more. The first six videos are embedded below, or you can watch them all on dartlang.org . Enjoy! A simple Dart script Runtime modes Variables Strings, numbers, and booleans Collections Functions are fun, pt 1 ...
