NotifierBuilder<N extends BaseNotifier<S>, S extends Object?> class

A widget that rebuilds when the state of the provided BaseNotifier changes.

NotifierBuilder is a convenience widget for listening to a BaseNotifier and rebuilding its child whenever the state changes, optionally using buildWhen to control rebuilds.

N is the type of BaseNotifier and S is the type of state managed by the notifier.
