    onBack: () -> Unit
) : SceneStrategyScope<T>(onBack)

Scope used to create a Scene from another Scene.

This Scope should be provided to the SceneDecoratorStrategy.decorateScene function to create Scenes.

Secondary Constructors

public constructor() : this(onBack = {})

Construct a SceneDecoratorStrategyScope suitable for calling SceneDecoratorStrategy functions in isolation.

For more complicated cases, such as ones where you want to test if onBack is called correctly, use rememberSceneState, which will construct its own internal SceneStrategyScope suitable for a Scene that closely mirror real scenarios and be passed to androidx.navigation3.ui.NavDisplay.
