Answer 1

this problem happened because of your connection;)

Answer 2

使用代理或 vpn 您的 IP 地址被阻止https://dart.dev/tools/pub/troubleshoot#pub-get-fails-from-behind-a-corporate-firewall

Answer 3

It may solve your problem:

1. add ".catch-pub" folder in your current project
2. add global environment variable "PUB_HOSTED_URL" with value "https://pub.dev/"

Answer 4

I had exactly the same problem and changed a few VPN , but it was still a problem and did not work

I used a service that changed DNS to fix the problem of sanctions and the problem was solved

Answer 5

After hours of trying to solve this problem, I finally found a solution.

First, you have to delete all the packages of project from pubspec.yaml file (you can comment these lines, so you don't forget what's packages used)

then add all the packages to the project from cmd with this command:

flutter pub add <package_name>

Make sure to use cmd, not powershell.

I hope this solution works for you.

Answer 6

It often related to VPN connection. before running flutter pub get , being sure that you can open https://developer.android.com/ site.
