Overview
ListenIt is a reactive state management package for Flutter that provides observable collections such as ListNotifier, MapNotifier, and SetNotifier, enabling developers to work with ValueNotifiers like Streams. It offers powerful operators for transforming and combining data streams, promoting a functional reactive programming style. Originally published as functional_listener, it simplifies state updates and subscriptions with minimal boilerplate. Ideal for managing dynamic data in responsive UIs.
