Getting Started

Practical Dart

1. 为何DocumentFragment须要clone后再加进文档里去？（p162的样例没有）
2. Dart 1.9+：async + await
3. element.onClick.listen( (evt){...} ); //<--- Stream对象？
4. `part`
5. num, int, double

The Power of HTML5 with Dart

1. use JS：JsFunction.apply() JsObject.callMethod()

   _jQuery = context['jQuery'];

2. Dart Summit 2015? dart2js
3. Completer？.complete(items); => .future()
4. import 'dart:indexd_db' as idb; //可定义索引？有点像MongoDB
5. event.preventDefault(); event.stopPropagation();
6. WebAudio
   1. BiquadFilterNode？=> 分析器？
7. typed_data
   1. SIMD（vector_math）：Int32x4、Float32x4
8. WebGL
   1. three.dart, StageXL*, Box2d & play_phaser
9. Isolate在browser上用Web Worker实现？

Developing a Mobile App with Dart

1. 300ms tap延迟：用meta viewport禁止
2. transform-style: preserve-3d;
3. *3D书架 with DeviceOrientation事件（.alpha/.beta/.gamma）
4. GPS不精确：Kalman滤波？

Web Components with polymer.dart

1. Web Components：Shadow DOM + Custom Elements + imports（M36+） + templates
2. 代码演示样例：

   var tpl = linkElement.important.querySelector('#id');

   Node n = tpl.content.clone(true);

   ... targetDiv.createShadowRoot().append(n);

3. document.registerElement('my-greeting', MyGreetingElement); <-- factory MyGreetingElement() => new Element.tag('my-greeting');
4. MutationObserver*
5. main() async { (await initPolymer()).run( (){...} );
6. *一路数据绑定

   @customTag('one-way-book')

   class OneWayBookElement extends PolymerElement { ...

7. 定制属性：if repeat
8. *二路数据绑定（Angular的简单实现？）
   1. <core-list> 无限列表

AngularDart

1. 3种bind：NgOneWay NgTwoWay NgAttr
2. Angular 2.0：使用TypeScript的扩展AtScript辨析的？支持编译到Dart？
3. 性能话题
   1. digest loop：对model的每一个变化？change会‘传播’...
   2. 不要嵌套ng-repeat，导致scopes泛滥
   3. <li ng-repeat="t in tasks | filter:term | orderBy:p track by t.id">
   4. dont't excess Formatter ...

Server-side apps with Dart

1. main()多个一个args參数而已

Testing and Profiling

1. 操作符重载？operator ==(Vector v) => ...
2. Mixins（略）
3. 測试AngularDart：Protractor/WebDriverJS（没有界面的浏览器）

Writing Native Extensions for the Standalone Dart VM

1. 略
