android - 颤振：添加http依赖项时出错

问题描述

我正在flutter docs中研究flutter 网络。我完全按照指导进行，但是当我添加 http 依赖项然后单击时Packages get出现错误。怎么了？感谢您的任何建议。

dependencies:
  flutter:
    sdk: flutter
  qrscan: ^0.2.17
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.3
  http: ^0.12.2  // http dependency I added

错误信息如下

Running "flutter pub get" in myProject...                        
Unexpected character (at character 1)
