Error in Boilerplate Mux

[tmtong]

For boilerplate.client xxx@hairyass:~/Documents/boilerplate_mux/bin$ dart client.dart client.dart:31:24: Error: Method not found: 'IOClient'. resty.globalClient = http.IOClient();

Apparently they change the interface, should be import 'package:http/io_client.dart'; resty.globalClient = IOClient();
