Problem to conect Flutterflow an

[bytonycruz]

I have a problem implementing the library, because when trying to connect to my broker it gives me an error, I use the Flutterflow platform so I am only implementing a bit of segmented code but I can't connect

      .startClean()
      .keepAliveFor(60)
      .withWillQos(MqttQos.atLeastOnce);

  // Asignar el mensaje de conexión al cliente
  client.connectionMessage = connMess;

  try {
    // Intentar conectar al broker MQTT
    await client.connect('user', 'password');
    return 'Conexión exitosa'; // Devolver éxito si la conexión fue exitosa
  } catch (e) {
    // Manejar excepción en caso de error durante la conexión
    print('Exception: $e');
    client.disconnect();
    return 'Error en la conexión: ${e.toString()}'; // Devolver error si hubo un problema en la conexión
  }
}

What error does it give you?

Try removing the will qos from the connection message.

A log would be useful
