calculateScene

public Scene<@NonNull T> calculateScene(
    @NonNull SceneStrategyScope<@NonNull T> receiver,
    @NonNull List<@NonNull NavEntry<@NonNull T>> entries
)

Given a SceneStrategyScope, calculate whether this SceneStrategy should take on the task of rendering one or more of the entries in the scope.

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.
