Flutter 在Riverpod ConsumerWidget中使用文本编辑控制器

我有一个ConsumerWidget，我用它来观察供应商的状态.一切都在工作，除了TextEditingControllers.每当我在文本字段中键入内容并单击手机键盘上的完成按钮时，文本字段又会变空.我认为这是由于该部件的状态.所以我的问题是，如何在ConsumerWidget里面使用TextEditingController，它没有createState方法？

这是我的代码.提前感谢:

class MainPage extends ConsumerWidget {
  const MainPage({super.key});

  @override
  Widget build(BuildContext context, ref) {
    // provider
    final roomListData = ref.watch(roomDataProvider);

    final roomService = RoomService();

    final roomIDController = TextEditingController();
    final roomPasswordController = TextEditingController();

    // UI screen size
    final size = MediaQuery.of(context).size;

    double deviceWidth = size.width;
    double deviceHeight = size.height;

    return Scaffold(
        backgroundColor: bluePrimary,
        body: SingleChildScrollView(
          child: roomListData.when(
              data: (data) {
                List<RoomModelResponse> roomList =
                    data.map((room) => room).toList();
                return SafeArea(
                    child: Container(
                  padding:
                      const EdgeInsets.symmetric(horizontal: 36, vertical: 16),
                  child: Column(
                      //crossAxisAlignment: CrossAxisAlignment.center,
                      children: [
                        Row(
                          mainAxisAlignment: MainAxisAlignment.spaceBetween,
                          children: [
                            IconButton(
                              iconSize: deviceWidth * 0.09,
                              icon: const Icon(Icons.person_outline,
                                  color: orangePrimary),
                              onPressed: () {
                                Navigator.push(
                                    context,

                                        builder: (context) =>
                                            const DetailedProfilePage()));
                              },
