- cleanUp()
- clear()
- dispose()

The 'dispose()' method in Flutter is used for manual disposal of resources and cleanup tasks for widgets. It is called when the stateful widget is removed from the tree, providing an opportunity to release resources such as closing streams or canceling subscriptions. Implementing 'dispose()' is essential for preventing memory leaks and ensuring proper resource management in Flutter applications.
