dart_thingsboard_pe_client's Issues

saveDevice doesn't support the entityGroupId field

The entityGroupId field documented here isn't supported:
https://thingsboard.cloud/swagger-ui/#/device-controller/saveDeviceUsingPOST

'CERTIFICATE_VERIFY_FAILED' exception is thrown, when connection to server with self-signed certificate.

. 'CERTIFICATE_VERIFY_FAILED' exception is thrown, when connection to server with self-signed certificate.
even if the CA is installed on the local device in my case android .

TimeseriesSubscriptionCmd field startTs doesn't work?

I want to implement real-time data acquisition using a time filter (5 minutes or 10 minutes earlier from the current one). I wrote this kind of code:

final telemetryService = thingsBoardClient.getTelemetryService();
    final currentTime = DateTime.now();
    final startTime = currentTime.subtract(
      const Duration(minutes: 5),
    );

    final subscription = TelemetrySubscriber(
      telemetryService,
      [
        TimeseriesSubscriptionCmd(
          entityId: DeviceId(deviceId).id!,
          entityType: DeviceId(deviceId).entityType,
          startTs: startTime.millisecondsSinceEpoch,
        ),
      ],
    );
    

I receive device data in real time, but the problem is that the startTs parameter is ignored and the data does not arrive as I mentioned - 5 minutes earlier. If I need to use a different method or approach to obtain data from a certain time to now, I will be glad to hear help. In case if everything alright please look through my issue. I tested both IOS simulator and Android device
Many thanks!

Proxy support isnt available

There is no way to configure a web proxy. this is a must in many professional environement running Thingsboard on premises .

ENTITY DATA QUERY WITH AGGREGATED TIME-SERIES TIMEWINDOW AND SUBSCRIPTION UPDATES EXAMPLE

Could you help me by obtaining the telemetry through the TelemetrySubscriber when I pass the agg, it stops sending the data

Null issues in getDeviceService().getUserDevices(PageLink(1))

Hi,
I faced the following error, while try calling _tbClient.getDeviceService().getUserDevices(PageLink(1)):
E/flutter ( 5652): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: type 'Null' is not a subtype of type 'Map<String, dynamic>' E/flutter ( 5652): #0 new Device.fromJson package:thingsboard_pe_client/…/model/device_models.dart:766 E/flutter ( 5652): #1 parseDevicePageData.<anonymous closure> package:thingsboard_pe_client/…/service/device_service.dart:8 E/flutter ( 5652): #2 dataFromJson.<anonymous closure> package:thingsboard_pe_client/…/page/page_data.dart:35 E/flutter ( 5652): #3 MappedListIterable.elementAt (dart:_internal/iterable.dart:413:31) E/flutter ( 5652): #4 ListIterator.moveNext (dart:_internal/iterable.dart:342:26) E/flutter ( 5652): #5 new _GrowableList._ofEfficientLengthIterable (dart:core-patch/growable_array.dart:206:27) E/flutter ( 5652): #6 new _GrowableList.of (dart:core-patch/growable_array.dart:153:28) E/flutter ( 5652): #7 new List.of (dart:core-patch/array_patch.dart:51:28)

While debugging, I recieved this:
in device_model.dart

With the following runtime variables:

Most of the devices parameter are empty, because I created it just with the necessary params with the API.
How can I use the method _tbClient.getDeviceService().getUserDevices(PageLink(1)) with this kind of devices?

Best regards :)
