我认为您缺少StatefulWidget，请尝试

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  late int first, second;
  late String islem;
  late String result, sonuc;
  @override
  void initState() {
    super.initState();
    first = 1;
    second = 2;
    islem = "islem";
    result = "A";
    sonuc = "sonuc";
  }

  @override
  Widget build(BuildContext context) {
    return Container();
  }
}
