notifyDependent method

@override void notifyDependent(covariant InheritedModel<T> oldComponent, 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 dependOnInheritedComponentOfExactType.
• getDependencies, which returns the current value for a dependent element.
• setDependencies, which sets the value for a dependent element.

Implementation

@override
void notifyDependent(InheritedModel<T> oldComponent, Element dependent) {
  final Set<T>? dependencies = getDependencies(dependent) as Set<T>?;
  if (dependencies == null) {
    return;
  }
  if (dependencies.isEmpty ||
      (component as InheritedModel<T>).updateShouldNotifyDependent(oldComponent, dependencies)) {
    dependent.didChangeDependencies();
  }
}
