What is the role of a state manager in an application and why is its use important?

The state manager in an application is responsible for storing and managing the current data that affects the interface display and application behavior. Its use is important because:

• It provides centralized data management, which simplifies maintenance and scaling.
• It allows for efficient UI updates when the state changes.
• It helps prevent data and interface desynchronization.

In Flutter, state managers (such as Provider, Bloc, Riverpod) help separate logic from UI, making the code cleaner and more testable.
