Restart your router! Works for me several times.
Make sure your network is not behind a proxy
Make sure you can ping to pub.dev without any packet loss
Try to close all of your dart.exe processes before retying to perform the flutter pub get
Try to delete an existing package from your pubspec.yaml and re-get it to see if it works
Try to manually add the package to your project

Prevent flutter pub get from retrying

Someone typed a private package url wrongly in pub spec yaml file.
As a result, pub get kept retrying but obviously never succeeded. This has wasted our github action build minutes.
How to prevent pub get from retrying after first failure?

Try this
- name: run pub get
run: flutter pub get
timeout-minutes: 2
It should stop trying after 2 minutes

its happening because your network connection is not proper or the server is not allowed to your country, or something wrong with your flutter
here is some ways to fix that problem i know
1-
use a vpn or proxy (its showing cant connect to the server so try to change the IP)
2-
check this link if vpn method is not working - https://dart.dev/tools/pub/troubleshoot#pub-get-fails-from-behind-a-corporate-firewall
3 -
try to upgrade your flutter just by one command
flutter upgrade
4 -
if its not working try to clean by this command
flutter clean
5 -
if anything wont working try to reinstall flutter (not recommended )
