虽然安装了flutter和dart的插件，还是提示没有安装。

主要原因就是在Android studio 4.1中plugin目录发生了变化

Plugin folder has changed in 4.1 version;

From : ~/Library/Application\ Support/AndroidStudio4.1

To: ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins

解决方案 可以用下面的指令软链接一下目录

ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
