How does the remember function determine when to free memory to avoid leaks?

The remember function in Jetpack Compose preserves state across recompositions by using the composition's lifecycle key. Memory is automatically released when the corresponding UI element is removed from the composition tree — that is, when its lifecycle ends. Compose tracks when an element is no longer needed and clears associated objects, preventing memory leaks. Thus, remember ties the lifetime of the saved state to the UI component's lifecycle, providing automatic memory management.
