One solution could be to use a shared state object between the parent and child views. The state object can be passed down through the view hierarchy and both parent and child views can access and modify its properties.

Another solution is to use a binding property as an intermediary between the parent and child views. The parent view can pass a binding property to the child view, allowing the child view to update the value of the property. When the property is updated, the parent view can observe the change and update its own state accordingly.

Additionally, one can make use of notification or delegation patterns where the child view can notify the parent view whenever a property is updated, and the parent view can update its own state accordingly.
