Description
I have added a waiting screen for the participants after joining the session if there is no host. And I have added a listener to get the host details. Using that I am displaying video screen. But this is not working on iOS. I have tested with 2 iOS simulator and Android Emulator. In android it is working fine as expected but in iOS, it is not working.

Error?
It is still in the waiting screen only.

How To Reproduce
I have added the sample code here.

Widget fullScreenView;
    Widget smallView;
    if (isInSession.value && isHostAvailable.value
        // &&
        // fullScreenUser.value != null &&
        // users.value.isNotEmpty)
        ) {
      fullScreenView = AnimatedOpacity(
        opacity: opacityLevel,
        duration: const Duration(seconds: 3),
        child: VideoView(
          user: fullScreenUser.value,
          hasMultiCamera: false,
          isPiPView: isPiPView.value,
          sharing: sharingUser.value == null
              ? false
              : (sharingUser.value?.userId == fullScreenUser.value?.userId),
          preview: false,
          focused: false,
          multiCameraIndex: "0",
          videoAspect: VideoAspect.Original,
          fullScreen: true,
          resolution: VideoResolution.Resolution360,
        ),
      );

      smallView = Container(
        height: 110,
        margin: const EdgeInsets.only(left: 20, right: 20),
        alignment: Alignment.center,
        child: ListView.separated(
          scrollDirection: Axis.horizontal,
          itemCount: users.value.length,
          itemBuilder: (BuildContext context, int index) {
            return InkWell(
              onTap: () async {
                onSelectedUser(users.value[index]);
              },
              onDoubleTap: () async {
                onSelectedUserVolume(users.value[index]);
              },
              child: Center(
                child: VideoView(
                  user: users.value[index],
                  hasMultiCamera: false,
                  isPiPView: false,
                  sharing: false,
                  preview: false,
                  focused: false,
                  multiCameraIndex: "0",
                  videoAspect: VideoAspect.Original,
                  fullScreen: false,
                  resolution: VideoResolution.Resolution180,
                ),
              ),
            );
          },
          separatorBuilder: (BuildContext context, int index) =>
              const Divider(),
        ),
      );
    } else if (isInSession.value && !isHostAvailable.value) {
      fullScreenView = Container(
          child: const Center(
        child: Text(
          "Waiting for host...",
          style: TextStyle(
            fontSize: 20,
            color: Colors.white,
          ),
        ),
      ));
      smallView = Container(
        height: 110,
        color: Colors.transparent,
      );
    } else {
      fullScreenView = Container(
          color: Colors.black,
          child: const Center(
            child: Text(
              "Connecting...",
              style: TextStyle(
                fontSize: 20,
                color: Colors.white,
              ),
            ),
          ));
      smallView = Container(
        height: 110,
        color: Colors.transparent,
      );
    }

onUserHostChanged listener:-

final userHostChangedListener =
          emitter.on(EventType.onUserHostChanged, (data) async {
        if (!isMounted()) return;
        isHostAvailable.value = true;
        print('called onUserHostChanged---> ');
      });

It is working fine in Android. But the listener is not calling in iOS.
