                ## 想想你已經完成的 這個代碼實驗室提供了大多數的 Dart 語言特性和許多庫的特性概覽。想學習更多的話請參考以下資源。 ## Dart 語言 [A Tour of the Dart Language](https://www.dartlang.org/docs/dart-up-and-running/ch02.html) 介紹了如何使用 Dart 基本特性,從變量和運算符到類和庫。這個代碼實驗室介紹了 Dart 的以下特性,這些特性在語言概覽中都有詳細介紹。 - 字符串插值 (`'$_firstName the $_appellation'`) - 級聯運算符 (`..`) - 胖箭頭 (`=>`) 函數語法 - 三目運算符 (`?:`) - 命名構造函數 (`PirateName.fromJSON(...)`( - 可選參數 - 類 - getters - 實例方法和屬性 - 類方法和屬性 - 頂級變量和函數 - 用 _as_ 做類型轉換 (`(e.target as InputElement)`) - 導入,帶 _show_ 的導入 (`import 'dart:math' show Random;`) - 泛型 - 異步支持(`async and await`) ## 在線文檔 ## Dart 庫 - [A Tour of the Dart Language](https://www.dartlang.org/docs/dart-up-and-running/ch02.html) 介紹了如何使用 Dart 庫的基本特性。 ## 類的API文檔 - [String](https://api.dartlang.org/dart_core/String.html), [List](https://api.dartlang.org/dart_core/List.html), [Map](https://api.dartlang.org/dart_core/Map.html), [Random](https://api.dartlang.org/dart_math/Random.html), [InputElement](https://api.dartlang.org/dart_html/InputElement.html), [ButtonElement](https://api.dartlang.org/dart_html/ButtonElement.html), [Event](https://api.dartlang.org/dart_html/Event.html), [HttpRequest](https://api.dartlang.org/dart_html/HttpRequest.html), [Future](https://api.dartlang.org/dart_async/Future.html) 和 [Stream](https://api.dartlang.org/dart_async/Stream.html) ## 庫的API文檔 - [dart:core](https://api.dartlang.org/dart_core.html), [dart:math](https://api.dartlang.org/dart_math.html), [dart:html](https://api.dartlang.org/dart_html.html), [dart:async](https://api.dartlang.org/dart_async.html) 和 [dart:convert](https://api.dartlang.org/dart_convert.html) ## JSON和本地存儲的API文檔 - [LocalStorage](https://api.dartlang.org/dart_html/Window.html#localStorage) 和 [JSON](https://api.dartlang.org/dart_convert.html#JSON) ## 反饋 請到 GitHub 上的 [dartlang repo](https://github.com/dart-lang/www.dartlang.org/issues) 提供反饋
