 * A {@link SingleParent} which contains a single child and does nothing,
 * passing all events through to its child. Useful for widgets that are only
 * used for logic, like {@link ThemeScope}.
 *
 * Can be constrained to a specific type of children.
 *
 * Since this does nothing on its own, it should not be used on its own.
 * Instead, extend this class if you are looking for a way to do wrapper widgets
 * that provide extra logic.
