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:
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel beta, v0.5.1, on Linux, locale en_US.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK 28.0.2)
[✓] Android Studio (version 3.1)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.

Linux用户:我cd到我的主目录，在.bashrc文件中添加export PATH="$PATH:/home/frodo/flutter/bin/flutter"，并将其源化以刷新.bashrc文件。这取决于您将Flutter SDK移动到哪里。
然后我就跑，医生。我得到了以下结果:
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel beta, v0.5.1, on Linux, locale en_US.UTF-8)

永久导出颤振路径:
export PATH="$PATH:/ PATH /to/dir" .bashrc文件
例如:
export PATH="$PATH:/home/frodo/flutter/bin/flutter"
并运行:
source .bashrc
如何永久设置$PATH在Linux/Unix
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel beta, v0.9.4, on Linux, locale en_IN)
[✓] Android toolchain - develop for Android devices (Android SDK 28.0.1)

一个对我有效的解决方案:
只需要安装插件。
Android Studio→菜单文件→设置→插件→浏览存储库
搜索“颤振”。
点击安装(会弹出一个关于Dart依赖的对话框。单击Yes)。
安装完成后，重新启动Android Studio。
现在跑扑医生:

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。
