Dart + HTML5 = Happy Web Developers

If you’ve been using HTML5 for a while, you’ve probably seen HTML5 Rocks. However, it’s not always clear how to translate these samples into Dart. To fix this, we’ve started a new project called dart-html5-samples, where we’ve started porting the HTML5 Rocks samples.

We’ve already ported a bunch of tutorials such as:

Along the way, we’ve occasionally encountered bugs in Dart. By filing these bugs on dartbug.com, we’ve not only been transparent about the process, but we've given the community a chance to vote for the features they find important.

Although we’ve ported a lot of samples, many more remain. If you’d like to help out, this would be a great way to contribute to the Dart project! Just fork the project on GitHub, and send us a pull request. Make sure you submit a bug in the issue tracker with the tutorial you plan on porting, so that others will know you are working on it. Finally, make sure to take a look at the other examples to get a feel for how we’ve structured things.

As always, if you’d like to chat more about this, feel free to send us email on the mailing list or ask questions on Stack Overflow.

Happy Hacking!

Dart in 2016: The fastest growing programming language at Google, 2nd fastest growing in TIOBE Index

Dart was the fastest growing programming language at Google in 2016 with millions of lines of code written. It also made it to TIOBE Index Top 20 this month (see TIOBE's methodology).

It takes time to build something as ambitious as Dart and, in some ways, Dart is still in its infancy. But we're glad the hard work is starting to pay off.

Many thanks to our amazing community!

We're going to celebrate by ... releasing 1.22 next week (as per our usual 6 week release schedule).

The new Google AdSense user interface: built with AngularDart

AdSense is a free, simple way to earn money by placing ads on your website. The team just launched a completely new version of their app for publishers. Read all about it here. We asked Daniel White, the tech lead for the project, some questions because the new UI happens to be built with Dart and Angular2.


AdSense launched way back in 2003. How long is it since the last big redesign?
Last big redesign was called ‘AdSense 3’ and launched about 6 years ago. It was written in Google Web Toolkit (GWT) and the UI has evolved through several iterations - but this is the first ground-up redesign in 6 years. There are a number of long-standing UX issues that we’ve taken the opportunity to solve. A big shout-out to our UX team who’ve been 100% behind this project. We couldn’t have done it without them!

How many software engineers worked on the project?
Purely on the AdSense applications, we have a team of close to 100. Around 25% of them write Dart.

How many lines of code?
We have around 160K LO…

A stronger Dart for everyone

We are constantly asking ourselves:
How do we make developers even more productive when writing Dart apps? We believe that a critical part of the answer to this question is to make strongmode – a sound static type system for Dart – the standard for all Dart developers.

Teams that use Dart to build apps like Soundtrap, AdWords, AdSense, and Greentea say they really enjoy using strong mode features, such as early error detection. In fact, teams that have switched completely to strong mode cite not only early error detection but also better code readability and maintainability as major benefits. We hear this both from small teams and – even more so – from large teams with hundreds of developers writing and maintaining millions of lines of Dart code. As Björn Sperber from Soundtrap says,
Strong mode and the smooth integration with IntelliJ is a joy to use and a huge improvement. If you’ve tried out Flutter, you’ve already used strong mode checks from the Dart analyzer.

Given the benefits …
