Overview
Provider is a lightweight, easy-to-use package that simplifies state management in Flutter by wrapping InheritedWidget. It enables efficient dependency injection and reactive updates without boilerplate. By leveraging the widget tree's build context, Provider allows widgets to efficiently access shared data and respond to changes. It promotes clean separation of concerns and enhances code reusability across different parts of an app.
