问题
Eclipse has a "Network Connections" page in its preferences that allows one to use proxies for network connections, so if I am behind a firewall I can use these connections. I don't see any such option in the Dart Editor. So, while I am at work, I cannot update from the network because of this. I can set the proxy in a browser, but not in Dart Editor. With a direct connection to an ISP, everything is okay, but not from an internal network.
Is there some way to fix this issue? If there is another way to allow the Dart Editor to connect to a network proxy I would be pleased.

You have to set environment variables
https://www.dartlang.org/tools/editor/troubleshoot.html#pub-get-firewall
http_proxy=http://<yourproxy>.<yourdomain>.com:9090/
https_proxy=https://<yourproxy>.<yourdomain>.com:9090/
no_proxy=localhost,127.0.0.0/8
If your proxy needs authentication, the setup will look more like the following:
http_proxy=http://<username>:<password>@<yourproxy>.<yourdomain>.com:9090/
https_proxy=https://<username>:<password>@<yourproxy>.<yourdomain>.com:9090/
DartEditor is no more
To enable Dart Editor to check for updates, add the following to the DartEditor.ini file:
-Dhttp.proxyHost=<yourproxy>.<yourdomain>.com
-Dhttp.proxyPort=9090
-Dhttps.proxyHost=<yourproxy>.<yourdomain>.com
-Dhttps.proxyPort=9090
If you need a user name and password for authentication, add:
-Dhttp.proxyUser=<username>
-Dhttp.proxyPassword=<passwordstring>
-Dhttps.proxyUser=<username>
-Dhttps.proxyPassword=<passwordstring>
