HMSUpdateListener listener class not working.

[asmitzz]

Version tried
Flutter 3.0.5
hmssdk_flutter: ^0.7.3

What happens -
After Joining the room HMSUpdateListener listener class is sometimes listening the events and sometimes it doesn’t listen.

Code --

class SdkInitializer {
  static HMSSDK hmssdk = HMSSDK();
}

final HMSInteractor hmsInteractor = HMSInteractor()

SdkInitializer.hmssdk.build();
 SdkInitializer.hmssdk.addUpdateListener(listener: hmsInteractor);
 
 class HMSInteractor implements HMSUpdateListener {
  HMSInteractor({required this.bloc});

  final RoomBloc bloc;

  @override
  void onChangeTrackStateRequest({required HMSTrackChangeRequest hmsTrackChangeRequest}) {
    // TODO: implement onChangeTrackStateRequest
  }

  @override
  void onJoin({required HMSRoom room}) {
    bloc.add(OnJoinRoomEvent(room: room));
  }

  @override
  void onMessage({required HMSMessage message}) {
    bloc.add(OnHMSMessageEvent(message: message));
  }

  @override
  void onPeerUpdate({required HMSPeer peer, required HMSPeerUpdate update}) {
   }
  }

Hi @asmitzz can you share what are the cases when you are not getting the events .

Hi @asmitzz can you share what are the cases when you are not getting the events .

I am not getting in any case. ( for ex - onJoin, onPeerUpdate )

@ygit I am also facing the same issue. HMSUpdateListener updates the very first time I join the meeting. After that no updates are sent from the class even when remote peer joins.

@kore-utkarsh which flutter version are you using ?

[kore-utkarsh]

@Decoder07

I am using
flutter - 2.10.5
hmssdk_flutter: ^0.7.4

[Decoder07]

Ok,are you getting onJoin callback or not even that?

[kore-utkarsh]

Yes, getting only the first time when user joins the room. After that not receiving any update in onJoin as well

[Decoder07]

onJoin gets called only once when the local Peer joins the room.For other peers onPeerUpdate gets called.Are you getting this callback ?

[kore-utkarsh]

No , onPeerUpdate not getting called for remote peers joining.

[Decoder07]

Hi can you check this implementation and try : https://github.com/100mslive/100ms-flutter/tree/main/sample%20apps/getx

[kore-utkarsh]

@Decoder07 Great! I will check and try implementing with this. Thank you!

[kore-utkarsh]

@Decoder07 Thanks for the reference sample app. Its now working for me. Issue has been ressolved
