When invoking pub, please set the PUB_ENVIRONMENT environment variable to vscode.dart-code.

This helps us track how pub is being invoked.

See an example here: https://github.com/dart-lang/sdk/blob/332dc7f3e90babd370fe4342603f5d74d8518a23/pkg/analysis_server/lib/src/plugin/plugin_manager.dart#L846-L861

A couple of notes:

• If PUB_ENVIRONMENT is already set, please amend your value w/ a :. So existing.value:vscode.dart-code

• When running tests, pass in a environment variable so we can know any hits to the pub site or via a test. Our convention is to use bot in the value. So for you dart-code.test.bot

Yes, I'd love the same model for invoking pub via flutter – so any call to flutter packages. I'll file a separate bug at https://github.com/Dart-Code/Flutter
