The getter 'connectionStatus' was called on null

Yep, I'll put a fix in

pr #89 is meant to fix this, and few other NPEs. Awaiting the maintainer for merging.

I think I observe the called on null also here (when connection gets lost, I guess):

  int publishMessage(
      String topic, MqttQos qualityOfService, typed.Uint8Buffer data,
      {bool retain = false}) {
    if (_connectionHandler.connectionStatus.state !=
        MqttConnectionState.connected) {
      throw ConnectionException(_connectionHandler.connectionStatus.state);
    }
    try {
      final PublicationTopic pubTopic = PublicationTopic(topic);
      return _publishingManager.publish(
          pubTopic, qualityOfService, data, retain);
    } on Exception catch (e) {
      throw InvalidTopicException(e.toString(), topic);
    }
  }

I use the client with IoT Watson MQTT server - I think it forces connection break twice a day.

Client updated as above, re-published at 5.5.3
