backgroundBuilder property
Background for the audio/video windows in a Live Streaming.
You can use any widget as the background for the audio/video windows. This can be a video, a GIF animation, an image, a web page, or any other widget.
If you need to dynamically change the background content, you should implement the logic for dynamic modification within the widget you return.
