I mean You either have to delete your current flutter directory , and build it from the flutter source or alternatively just do a ```flutter version ``` in the terminal and see what happens. — 钟智强, Aug 18 '20 at 06:26

@SruthiMariaThomson This thread might help. Have a look - https://github.com/flutter/flutter/issues/12666 — Jigar Patel, Aug 18 '20 at 06:35
Did you declare PATH variable? Is your flutter install correctly? Refer the tutorial here : https://flutter.dev/docs/get-started/install — 钟智强, Aug 18 '20 at 06:36

Try to use from some VPN connection for your system.

This issue happens when server does not reachable.

Second way : Use google DNS for your connection :

primary : 8.8.8.8

secondary : 8.8.4.4
