void show(BuildContext context,
    {bool root = false,
    bool hideCurrent = true,
    ScaffoldState? scaffoldState}) {
  if (scaffoldState != null) {
    if (hideCurrent) {
      ScaffoldMessenger.of(context).hideCurrentSnackBar();
    }
    ScaffoldMessenger.of(context).showSnackBar(this);
  } else if (root) {
    final state = context.findRootAncestorStateOfType<ScaffoldState>();
    if (hideCurrent) {
      ScaffoldMessenger.of(state!.context).hideCurrentSnackBar();
    }
    ScaffoldMessenger.of(state!.context).showSnackBar(this);
  } else {
    if (hideCurrent) {
      ScaffoldMessenger.of(context).hideCurrentSnackBar();
    }
    ScaffoldMessenger.of(context).hideCurrentSnackBar();
