In order to provide a solution for this situation, Flutter provides a special widget called InheritedWidget that defines a context at the root of a sub-tree. It can efficiently deliver this context to every widget in that sub-tree. This widget is specially designed to hold data and to provide it throughout the widget tree, irrespective of its depth. InheritedWidget is the base class for widgets that efficiently propagate information down the widgets tree. All widgets part of that sub-tree will have to ability to interact with the data which is exposed by that InheritedWidget.
