          title: const Text('Agora UI Kit'),
          centerTitle: true,
        ),
        body: SafeArea(

              AgoraVideoViewer(
                client: client,
                layoutType: Layout.floating,
                enableHostControls: true,

              ),
              AgoraVideoButtons(
                client: client,
                onDisconnect: () => Navigator.pop(context),
              ),
            ],

[Meherdeep]

@itsdani121 Should be solved with the latest release

[itsdani121]

Latest release give analysis issues kindly check it

[Meherdeep]

@itsdani121 pub.dev was evaluating the package. You should be able to use it now :)

[itsdani121]

But on pub latest version it says rtc connection error

[Meherdeep]

Can you share the logs

[Marshysaurus]

@Meherdeep I have agora_uikit: 1.3.7 and this is still an issue

What happens is that another user joins the call and it's all fine, their view floats in the upper part of the screen. However, when the user taps on their 📌 icon, the error is thrown. Here are some images to illustrate:

These are my logs during the call:

The following assertion was thrown building:

No, the error still persists and the team are ignorant about it.
