When writing onLoad in VSCode, it auto-completes as FutureOr<void> onLoad().
However, most Flutter Flame sample code online uses Future<void> onLoad(), so I’ve been manually writing it without relying on auto-completion.

What exactly is FutureOr<void> onLoad ?

class FooComponent extends PositionComponent {
  @override
  FutureOr<void> onLoad() {
    // TODO: implement onLoad
    return super.onLoad();
  }
}
