在使用 flutter create命令创建flutter工程时，如果报Cannot create a project within the Flutter SDK. Target directory '/Users/ksnowlv/Music/flutter/flutter/my_app' is within the Flutter SDK at '/Users/ksnowlv/Music/flutter/flutter'的错误，注意不要在flutter SDK目录及子目录下创建工程，可考虑在其它目录下创建工程。例如平级目录
ksnowlvdeMacBook-Pro:flutter ksnowlv$ ./flutter/bin/flutter create my_app
