Overview
StateNotifier is a Dart package that extends ValueNotifier with enhanced features for state management outside the Flutter framework. It provides a clean, reactive way to manage state with built-in support for async operations, error handling, and debugging tools. Designed for use in non-Flutter environments like web, desktop, and server-side applications, it integrates well with dependency injection and promotes separation of concerns. The package offers improved performance and developer experience through immutable updates and streamlined subscriptions.
