在Windows上，运行Flutter闪退，后来先运行cmd，再运行Flutter，发现提示
Unable to find git in your PATH.
但是明明git就可以访问的，出现此原因其实目前Flutter目录是git无权访问
在Flutter目录下执行git status
提示：
fatal: detected dubious ownership in repository at 'D:/flutter'
'D:/flutter' is owned by:
'S-1-5-32-544'
but the current user is:
'S-1-5-21-3692714792-1416469238-2434195209-20124'
To add an exception for this directory, call:git config --global --add safe.directory D:/flutter
在目录下执行
git config --global --add safe.directory D:/flutter
再执行flutter问题解决。
