StatefulDataDefaultViews class
Provides default views for StatefulDataView widgets placed below in the widget tree.
It is useful when the same data state views can be used by multiple StatefulDataView widgets. So they could be specified once by this StatefulDataDefaultViews widget, and then be accessed by StatefulDataView or other widgets.
This widget must be placed upper in the widget tree than any widget interested in views defined by it.
