Is the context necessary in custom hooks?

Question

According to the Flutter hooks documentation on creating custom hooks, the author mentioned an example like the following,

ValueNotifier<T> useLoggedState<T>(BuildContext context, [T initialData]) {
  final result = useState<T>(initialData);
  useValueChanged(result.value, (_, __) {
    print(result.value);
  });
  return result;
}

with the hook consuming the context of the widget. That context is not used anywhere in the hook, but it is not a dead code according to the linter. So I just want to know if that context is necessary or not? and if so, why?
