What are the best practices for managing state in Flutter applications?

Managing state in Flutter applications can be done effectively by taking various approaches, including Provider, Riverpod, and BLoC. The Provider package is one of the most commonly used for simple state management because of its clean and efficient sharing of states between different parts of an app. The BLoC pattern scales well for complex applications, as it introduces a formal separation of business logic from your UI components. Using Flutter’s setState might be fitting for a local state within a single widget but does not scale at an app level.
