public final class SavedState

An opaque (empty) common type that holds saveable values to be saved and restored by native platforms that have a concept of System-initiated Process Death.

That means, the OS will give the chance for the process to keep the state of the application (normally using a serialization mechanism), and allow the app to restore its state later. That is commonly referred to as "state restoration".

required to act as a source input for a SavedStateReader or SavedStateWriter.

This class represents a container for persistable state data. It is designed to be platform-agnostic, allowing seamless state saving and restoration across different environments.
