Improvements to debugger and a new refactor added to Dart Editor

Posted by Devon Carew


A new Dart Editor build is now available. Highlights from this build include:
  • The 32 bit Dartium build has beed added back into the 32 bit Editor build for Linux (and the 64 bit Editor build still contains the 64 bit Dartium build).
  • 5 analysis issues fixed.
  • Dartdoc improvements; we now syntax highlight dartdoc comments, and properly indent the next line when the user hits enter.
  • Added a top level "Refresh" menu item (and an associated keybinding).
  • Added an "Inline local variable" refactoring.
  • Windows launching fixes! We've received lots of reports of issues launching Dartium on Windows. We found and fixed an issue in the editor; in addition, we now disable Chrome extensions when launching Dartium. Some extensions were causing issues when trying to connect the debugger. We also include additional diagnostic information for Windows; please send feedback if you continue to see issues when trying to launch Dartium on Windows.
  • We now display print() output in the Editor for JavaScript launches. This is especially useful for getting logging information back from some mobile devices, like iOS devices.
  • Both the command-line debugger and the Dartium debugger now show the value of library (global) variables.
  • The command-line debugger can now display list elements.
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…
