  final TextEditingController controllerDetallesMotherboard =
      new TextEditingController();
  final TextEditingController controllerFechaMotherboard =

      @required Key keyForm,
      @required String saveNumInv,
      @required String saveMarca,
      @required String saveModelo,
      @required String …
