I'm not sure if chat-client.dart referes to something we ship. I suspect the issue is that chat-client.dart is a web app, and probably imports dat:html. In which case, importing dart:io will not work.

It think the resolution for this issue is to add a warning or an error when we detect incompatible imports. In the simple case, displaying an error if the same library tries to import both dart:io and dart:html.

Konstantin just checked in a CL so that importing both dart:html and dart:io will produce a warning. Please re-open this issue if that doesn't satisfy the need.
