   print("${device.id}: ${device.position.geoPoint.latitude} / " +
      "${device.position.geoPoint.longitude}");
});

trac.query.devices().then((List<Device> devices) {
   print("$devices");
});

   final List<Device> pos = await trac.query.positions(
      deviceId: "1", since: Duration(hours: 3));
