Implementation
static Future<ServiceProtocolInfo> getInfo() async {
// Port to receive response from service isolate.
final RawReceivePort receivePort = new RawReceivePort();
final Completer<Uri> uriCompleter = new Completer<Uri>();
receivePort.handler = (Uri uri) => uriCompleter.complete(uri);
// Request the information from the service isolate.
_getServerInfo(receivePort.sendPort);
// Await the response from the service isolate.
Uri uri = await uriCompleter.future;
// Close the port.
receivePort.close();
return new ServiceProtocolInfo(uri);
