How is the stateless widget different from the stateful widget in Flutter?

The key difference between stateless and stateful widgets in Flutter is the handling of internal state. Stateless widgets are immutable, meaning their properties cannot change once they are initialized. In contrast, stateful widgets maintain mutable state, allowing them to change and update over time. Stateful widgets are used when the part of the user interface can change dynamically based on user interactions, making them suitable for scenarios such as form inputs or dynamic content.
