Answer 2

This is a country-specific problem. In some countries, you got this error like Bangladesh and some African countries. I got a solution to this problem, that is use VPN software when you want to get Packages. VPN software uses other country's IP addresses where this google service works perfectly, So you can easily download packages.

Answer 3

Use vpn. If you are not using not prepackaged packages: stop the process with "ctrl + c" and try it on project location:

flutter pub get --offline

Answer 4

Fixed the issue, my Local Isp blocked pub.dartlang.org that's why it happens.
