NotifierConsumer<N extends BaseNotifier<S> , S extends Object?> class
A widget that both rebuilds and listens to state changes from a BaseNotifier.
NotifierConsumer allows you to rebuild the widget tree and perform side effects
in response to state changes, using buildWhen and listenWhen to control behavior.
N is the type of BaseNotifier and S is the type of state managed by the notifier.
