Thank you IKai Lan for taking time to answer my question, but I know
how to kill a process and currently I am stopping server by doing the
same. I usually dont like to KILL anyone (even a process) . So is
there any command to stop development server? Or is that google forgot
to provide any command
It's probably a bug. Can you look for a similar issue here?

If it doesn't exist, please file reproduction steps.
Using kill on a process is less than ideal, but it's a development server so
there shouldn't be any detrimental effects. You
