Dart SDK Version: Dart VM version: 2.1.2-dev.0.0.flutter-0a7dcf17eb (Tue Feb 12 01:59:15 2019 +0000) on "windows_x64"
Windows 10 OS
I will start by saying I have thoroughly read all the Dart/Pub/Flutter issues I can find on this subject, and none of the solutions have fixed the issue for me. I am not behind a proxy.
I have a new installation of Dart and Flutter and am trying to do this simple tutorial: https://flutter.dev/docs/get-started/codelab
When I run flutter packages get, or for more information, flutter packages pub get --verbosity=all, I get the following error:
HTTP error:
| HandshakeException: Handshake error in client (OS Error:
| CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:352))
My flutter doctor -v output is:

I have installed android studio, flutter, dart on a different machine with Windows 10 on the same network, and had no problems. But it is not the computer I need for development.
Things I have tried that did not resolve the issue:
- Disable Windows Defender (no other antivirus on the computer)
- Set the DART_VM_OPTIONS environment variable pointing to a self-signed certificate as per the discussion in this issue: Iron Port TLS 1.0 proxy, pub get fails #25615 (although I've not sure if I'm doing this correctly)
- Set the PUB_HOSTED_URL and FLUTTER_STORAGE_BASE_URL to the China repositories as in this issue: Handshake Error - Connection Verify Failed #32131
- Set the https_proxy environment variable to various values: localhost:8080, localhost:443, 127.0.0.1:8080, 127.0.0.1:443, localhost:80, 127.0.0.1:80
- Tried all of the above in an administrator privileges CLI and Powershell window
- I can also access pub.dartlang.org in Chrome just fine
Hoping someone can help figure out what may be causing this, as I can't use dart without resolving. Thanks!
