notifyDependent method

@override void notifyDependent(covariant InheritedMediator<TModel> oldWidget, Element dependent)

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.

Implementation

@override
void notifyDependent(InheritedMediator<TModel> oldWidget, Element dependent) {
  final HashSet<Object>? dependencies =
      getDependencies(dependent) as HashSet<Object>?;
  if (dependencies == null) return;
  if (dependencies.isEmpty ||
      widget.updateShouldNotifyDependent(oldWidget, dependencies)) {
    dependent.didChangeDependencies();
  }
}
