Dart is now on GitHub

Dart is an open-source programming language, with contributors working on the language, libraries, tools, and packages. To make working with our community even easier, today we are announcing that we've fully settled into our new home on GitHub. We invite you to follow along and contribute at https://github.com/dart-lang.


The Dart SDK now has its own repository, joining the numerous Dart tools and packages already in our GitHub org. We’ve moved all the SDK issues over (keeping the original issue numbers!), and dartbug.com now points to GitHub's issue tracker for the Dart SDK.

Getting the SDK source is easy, and we've documented the contribution workflow. Our development tools are optimized for code reviews on Rietveld, Chromium's code review system, and they make it easy to start a review and cleanly land a patch. For very small patches, contributors can use a standard GitHub pull request.

One of the easiest ways to start contributing to Dart is to work on one of our packages. Individual packages (for example, args, http, and test) now have their own repos, complete with their own issue trackers and buildbots. To get started, check them out and find issues marked "help wanted". And of course, we encourage everyone to continue filing issues with dartbug.com.

We hope our move to GitHub helps more Dartisans become active participants in the future of Dart.

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).

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 Рeven more so Рfrom 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 …

AngularDart 3.0: Easy upgrade, better performance

AngularDart 3.0 is now available. It brings better performance and smaller generated code, while also making you more productive.


Version 3.0 is an evolution: although it has some breaking changes (detailed below), it is a smooth upgrade due to minimal public API adjustments. Most of the progress is under the hood—in code quality, stability, generated code size, performance, and developer experience.

Code quality:
2731 instances of making the framework code more type safe (using sound Dart).The AngularDart framework code size is down by 12%.Many additional style updates to the codebase:Changed to use idiomatic <T> for generic methods.Removed NgZoneImpl, all the code exists in NgZone now.Stability:
Many CSS encapsulation fixes due to update with csslib package.Fixed bugs with IE11.

Performance:
For the Mail sample app, we see 30% faster time-to-interactive (currently 3812 ms on a simulated 3G connection, measured via Lighthouse).Our large app benchmark shows 2x faster render times of…
