notifyDependent method

@override void notifyDependent(covariant InheritedWidget 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(covariant InheritedWidget oldWidget, Element dependent) {
  final condition =
      getDependencies(dependent) as _InternalServiceListenCondition?;
  if (condition == null || condition(this) == true) {
    dependent.didChangeDependencies();
  }
}
