按照http://www.dartlang.org/docs/tutorials/web-ui/上的教程，我刚刚实现了第一个示例并尝试构建。

构建命令：

$DART_SDK/bin/dart --package-root=packages/ packages/web_ui/dwc.dart index.html

使用 SDK 版本 17072 提供堆栈跟踪

SEVERE index.html: exception while reading file, original message:

17072 是一个相当古老的（在 Dart 年代）构建 - 当前版本（在撰写本文时）可在http://www.dartlang.org/downloads.html下载是 17657，并且这个添加了 List.reversed 的更改日志已提交在r17402
