Got TLS error trying to find package ABC at https://pub.dartlang.org

Question

I am using Linux Ubuntu 18.04.1 LTS. I am creating a new Flutter project through git bash or terminal or from Visual Studio Code directly but gets an error which says:

Got TLS error trying to find package cupertino_icons at https://pub.dartlang.org

In Flutter Project's pubspec.yaml file I removed the line "cupertino_icons: ^0.1.2" in an attempt to resolve the issue but gets the same error on another package:

Got TLS error trying to find package vector_math at https://pub.dartlang.org

I've googled alot but couldn't find the right solution. Please do tell me the main cause of this issue and how to solve it?

Answer 1

For those who find their way to this answer via Google, here's what worked for me. I am running Windows 10 x64 behind a corporate firewall (Zscaler), and my client uses a self-signed cert. I eventually found this Github comment which described creating a system environment variable pointing to the self-signed cert. Once I created the variable and restarted my command prompts, I was able to execute commands like flutter pub get.
