visitChildren method

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

  final dependents = _dependents;
  if (dependents != null) {
    for (var i = 0; i < dependents.length; i++) {
      final dependent = dependents[i].source;
      if (dependent is ProviderElementBase) elementVisitor(dependent);
    }
  }
}
