SavedStateRegistryOwnerDelegatesKt

public static final @NonNull ReadWriteProperty<Object, @NonNull T> <T extends Object> saved(
    @NonNull SavedStateRegistryOwner receiver,
    @NonNull Function0<@NonNull T> init
)

Returns a property delegate provider that manages the saving and restoring of a value of type T within the SavedStateRegistry of this SavedStateRegistryOwner.

This is a convenience overload that uses the serializer function to obtain the serializer for the reified type T.

The name of the property will be used as the key for storing the value in the SavedStateRegistry.
