bool isValid() =>

    components.length <= 20 &&
    components.every((e) {
      switch (e) {
        case GameDialogMarkdownComponent():
          return e.content.length <= 5000;
        case GameDialogTextFieldComponent():
          return e.label.length <= 50 &&
              (e.id?.length ?? 0) <= 100 &&
              (e.placeholder?.length ?? 0) <= 50;
        default:
          return false;
      }
    }) &&
    (actions ?? [])
        .every((e) => e.label.length <= 50 && (e.id?.length ?? 0) <= 100);
