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 2.1 and new Components

AngularDart got its own dedicated team 5 months ago. Last month, we launched 2.0 final on the Dart Developer Summit. Today, we’re releasing the first minor release after that: 2.1.

Since the focus of AngularDart is Productivity, Performance, Stability, there are no major breaking changes (see the changelog) — but a lot of behind-the-scenes improvements. Your apps will get slightly smaller and faster (even relative to 2.0 which already made huge strides in size and performance since the compiled-from-TypeScript days).

Many features that AngularJS had to implement for JavaScript and TypeScript are not needed in Dart (because Dart already has those features out-of-the-box). So we’re removing them from AngularDart. Renderer is deprecated in favor of plain-old dart:html. NgPlural is going away — Dart programs can use the package:intl library.

New components

On the Dart Developer Summit, we launched AngularDart Components — the material design widgets Google is using in customer-facing apps …
