I do not receive new messages with Strophe

I used the example here example with strophe JS and it worked correctly, but when I tried to do the same with stroph Dart, it does not work and I can not receive messages.

eliminating connection.send($pres().tree()); of the code in JS I do not receive messages either, the problem is that I do not know how to transform that to Strophe Dart.

String mi_jid;
  var _domain = "localhost";
  String host = 'my_server_ip';
  StropheConnection _connection;


  log(msg)
  {
    print(msg);
  }


  onMessage(msg) {
    print("mensaje recibido");
    var to = msg.getAttribute('to');
    var from = msg.getAttribute('from');
    var type = msg.getAttribute('type');
    var elems = msg.getElementsByTagName('body');

    if (type == "chat" && elems.length > 0) {
      var body = elems[0];

      print('ECHOBOT: I got a message from ' + from + ': ' +
          Strophe.getText(body));

    }

    // we must return true to keep the handler alive.
    // returning false would remove it after it finishes.
    return true;
  }


  onConnect(status)
  {
    if (status == Strophe.Status['CONNECTING']) {
      log('Strophe is connecting.');
    }
    else if (status  == Strophe.Status['CONNFAIL']) {
      log('Strophe failed to connect.');
    } else if (status == Strophe.Status['DISCONNECTING']) {
      log('Strophe is disconnecting.');
    } else if (status == Strophe.Status['DISCONNECTED']) {
      log('Strophe is disconnected.');
    }
    else if (status == Strophe.Status['CONNECTED']) {
      log('Strophe is connected.');
      log('ECHOBOT: Send a message to ' + _connection.jid +
          ' to talk to me.');

      _connection.addHandler(onMessage, null, 'message', null, null,  null);

    }
  }


  void _inicia_sesion() async {

    _connection = Strophe.Connection("ws://"+ host +":7070/ws/");
    print("iniciando conexion....");

    /*
    _connection.xmlInput = (elem) {
      print('input $elem');
    };
    _connection.xmlOutput = (elem) {
      print('output $elem');
    };
    */

    _connection.connect('user1@localhost', 'password',
            (int status, condition, ele){

              onConnect(status);
        });
  }

Please help me :frowning:

@anonimo have u found the solution ?

Yes, after adding addHandler for new messages, I add another line of code, with what remains:

else if (status == Strophe.Status['CONNECTED']) {
      log('Strophe is connected.');
      log('ECHOBOT: Send a message to ' + _connection.jid +
          ' to talk to me.');

      _connection.addHandler(onMessage, null, 'message', null, null,  null);
      _connection.send(Strophe.$pres().tree());
 }
