Scene Camera instance in Cesium Widget

Is there any recommended way to get the current camera instance in a cesium widget?

In detail, when we create a cesium viewer instance, we can access the camera instance through its scene instance.I want to fetch that camera instance in my custom cesium widget.

I am a newbie in developing cesium widget.So pardon me if it is a stupid question.Thanks.

The scene is the definitive owner for the camera object, but the widget also has a shortcut camera property which returns the same object.
