@Composable
public @NonNull Scene<@NonNull T> calculateScene(
    @NonNull List<@NonNull NavEntry<@NonNull T>> entries,
    @NonNull Function1<@NonNull Integer, Unit> onBack
)

Given a back stack of entries, calculate whether this SceneStrategy should take on the task of rendering one or more of those entries.

By returning a non-null Scene, your Scene takes on the responsibility of rendering the set of entries you declare in Scene.entries. If you return null, the next available SceneStrategy will be called.

Parameters
@NonNull List<@NonNull NavEntry<@NonNull T>> entries

The entries on the back stack that should be considered valid to render via a returned Scene.
@NonNull Function1<@NonNull Integer, Unit> onBack

a callback that should be connected to any internal handling of system back done by the returned Scene. The passed Int should be the number of entries were popped.
