notifyDependent method Null safety
- covariant InheritedWidget oldWidget,

Called by notifyClients for each dependent.
Calls dependent.didChangeDependencies() by default.
Subclasses can override this method to selectively call didChangeDependencies based on the value of getDependencies.
See also:
- updateDependencies, which is called each time a dependency is created with dependOnInheritedWidgetOfExactType.
- getDependencies, which returns the current value for a dependent element.
- setDependencies, which sets the value for a dependent element.
- InheritedModel, which is an example of a class that uses this method to manage dependency values.

dependent.didChangeDependencies();
