visitChildren method

void visitChildren({ required void elementVisitor(ProviderElementBase<Object?> element), required void notifierVisitor(ProxyElementValueNotifier<Object?> element), })

Visit the ProviderElements of providers that are listening to this element.

A provider is considered as listening to this element if it either watch or listen this element.

This method does not guarantee that a dependency is visited only once. If a provider both watch and listen an element, or if a provider listen multiple times to an element, it may be visited multiple times.

Implementation

void visitChildren({
  required void Function(ProviderElementBase<Object?> element) elementVisitor,
  required void Function(ProxyElementValueNotifier<Object?> element)
      notifierVisitor,
}) {
  for (var i = 0; i < _providerDependents.length; i++) {
    elementVisitor(_providerDependents[i]);
  }

  for (var i = 0; i < _subscribers.length; i++) {
    elementVisitor(_subscribers[i].dependentElement);
  }
}
