我正在我的Linux Ubuntu 16.04 (Xenial Xerus)系统上配置Flutter SDK。为什么在运行颤振诊断程序时出现以下错误?
我已经在.bashrc文件中为flutter和dart指定了path，但是当我运行flutter doctor时，我得到了这个错误:

在Windows上安装它的最好方法

打开Android Studio，菜单文件→设置→插件，确保安装了Flutter和Dart
转到Visual Studio代码扩展，并安装Flutter和Dart扩展
我遇到了同样的问题，上面的答案都没有解决它，所以我去了Flutter官方GitHub存储库，并在那里找到了答案。这是链接，你必须遵循所有这些步骤。

颤振升级
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
对于Mac，你可以按照Andrew回答的那样做:
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
flutter doctor -v
然后，如果问题仍然存在，那么只需转移到beta通道并升级Flutter。然后它会修复它。
颤振通道
颤振升级
可以作为可选步骤启用Flutter web。
