我建议清除android-studio-dir和android-sdk设置，让flutter自动检测它们的路径：

删除包含Android Studio之前版本的配置文件的文件夹解决了我的问题。更新后我有2个版本的Android Studio。
因此，我删除了版本3.3（.AndroidStudio3.3）的配置文件，只保留版本3.4（.AndroidStudio3.4）的配置文件
如果您是Ubuntu用户并且默认安装了Android Studio，您可以在home目录中找到这些文件夹。这些文件夹是隐藏的，因此您必须先取消隐藏它们。
请确保在更新后出现提示时导入以前的设置，否则您必须在删除旧配置文件之前重新安装所有使用过的依赖项。

我删除了flutter的和Android Studio目录，我再次安装他们，问题很快回来.
但我尝试了这两个命令，它们被证明是有帮助的：

顺便说一句，如果你碰巧有一个时间机器的usb驱动器插入，任何vscode和android安装得到注意和显示。解释为什么我的usb驱动器是意外忙碌。弹出它，并做flutter医生一次。
