Dart Editor now analyzes as you type

A new Dart Editor build is available at www.dartlang.org/editor. Changes include:


  • We now have analysis as you type! You're now alerted about errors as you type without first having to save the file.



  • Debugger expression evaluation - when paused at a breakpoint in Dartium it's now possible to evaluate expressions. You can access this feature from the 'Show Expressions' toolbar button in the Debugger view. This is a Dartium only feature currently; support for the command-line debugger is forthcoming.
  • We have two new quick fixes; one for creating a class and one for creating a constructor.
  • Fixes for debugging command-line and Dartium apps when used with Pub and the packages directory.
  • Tweaks to the @deprecated and @override presentation.
  • And fixes to the cleanups, to our auto-update, for a debugger crash with Dartium, as well as 11 analysis fixes.
In addition, if you're running MacOS 10.8 (Mountain Lion), it will complain that our 64-bit distribution is corrupted. The net-net is that we need to sign our binary, but in the meantime two workarounds are to download our 32-bit build instead, or to change your security settings to let you run applications downloaded from anywhere.

And as always, view the changelog for the full list of changes, and to get started with the Editor see our tutorial.

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 – 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 …

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…
