Dart Team Updates, Sep 5 - 18, 2012

Summary
  • Dart is getting closer to reaching Milestone 1. We have been doing a lot of M1 bug-fixing across sub components. There is now a Dart web components sample available. We have a new pub package layout and the editor now comes with the possibility to auto-update.

Details

Dart Editor:
  • Lots of SDK changes: dart:dom was removed and several libraries moved from dart-sdk/lib to dart-sdk/pkg.
  • Run the Dartdoc tool from the Editor - see Tools > Generate Dartdoc.
  • Code completion now supports the method cascades syntax (foo..and()..another()..thing()).
  • New clean up to convert old optional parameters to the new optional named ones where possible.
  • New refactoring to convert optional positional parameters to named.
  • New "Convert Method to Getter" refactoring.
  • Rename refactoring improvements - if there are potential references to a field or method, we will warn the user and display a preview dialog.
  • New Quick Fix to create a library import for unresolved functions and fields.
  • No longer report 'no such method' warnings if class defines 'noSuchMethod()'.
  • Warnings created for inferred types are now displayed only in the source itself - See them in the Problems view by toggling the 'show informational messages' button.
  • Using the old catch syntax is now an error.
  • Files view now displays whether a dart: library is client only (like dart:html) or server only (like dart:io).
  • New preference to enable code folding.
  • Fixed an issue where our search box would not consistently show SDK types.
  • Fix for a crash related to the break-on-exceptions feature, and for a crash that could occurred when launching Dartium with breakpoints set.
  • Various analysis fixes, debugger UX improvements, and performance improvements for large projects.

Dart UI [dart:html, web components]:

Dart SDK and build:
  • lib/ directory split into lib/ and pkg/ . In the SDK, lib/ and dart: are now identical.

Pub:
  • Integrate bootstrap into pub.dartlang.org and give it a basic look and feel
  • Show description, authors, and homepage on package pages
  • Integrate docs into pub.dartlang.org
  • Work on launch process for pub.dartlang.org: talk to pcounsel, create launch, write design doc and privacy design doc, etc.
  • Change package layout, and update pub, explain to the list, update our packages, and update the docs

Dart Server [dart:io, etc.]:
  • Lots of M1 bugfixing.

AngularDart 4

AngularDart v4 is now available. We've been busy since the release angular2 v3.1.0 in May. Not only did we "drop the 2", but we also improved the compiler and tightened up the framework to give you smaller code, we updated the package structure to improve usability, and we added several new features. Check out the updated documentation to get started.
Just angular Upgrading to v4 will require more than updating your version constraint. The package has changed names (back) to angular – dropping the 2. You'll need to update your pubspec.yaml and the corresponding imports in your code. In most instances, find-and-replace should do the trick. Going forward, the package will be called package:angular. We'll just update the version number.
Smaller code The updated compiler in 4.0 allows type-based optimizations that not only improve runtime performance but generate better code because we are able to strongly type templates. A big result of the update is that many ap…

The new AdWords UI uses Dart — we asked why

Google just announced a re-designed AdWords experience. In case you’re not familiar with AdWords: businesses use it to advertise on google.com and partner websites. Advertising makes up majority of Google’s revenue, so when Google decides to completely redo the customer-facing front end to it, it’s a big deal. The Dart team is proud to say that this new front end is built with Dart and Angular 2. Whenever you asked us whether Google is ‘even using Dart for anything,’ this is what we had in mind but couldn’t say aloud. Until now. We asked Joshy Joseph, the primary technical lead on the project, some questions. Joshy is focusing on things like infrastructure, application latency and development velocity, so he’s the right person to ask about Dart.Q: What exactly did we launch on Monday?It’s a complete redesign of the AdWords customer experience that is rolling out slowly as a test to a small initial set of advertisers. The most noticeable thing is probably the Material Design look and f…

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 …
