我得到了错误：“延迟初始化错误：字段'_splitScreenMode@963084504'尚未初始化”，当我尝试创建第二页（启动后的下一页，名称为：pageOne）通过导入flutter_screen_util包进行响应。我添加了.w和.h用于宽度和高度测量。我是flutter新手，所以我不能识别此错误。
我的启动画面代码：

import 'package:flutter/material.dart';

import 'package:my_wallet/screens/categories.dart';

import 'package:my_wallet/screens/page_1.dart';

class ScreenSplash extends StatefulWidget {
  const ScreenSplash({Key? key}) : super(key: key);

  @override
  State<ScreenSplash> createState() => _ScreenSplashState();
}

class _ScreenSplashState extends State<ScreenSplash> {
  @override
  void initState() {
    checkUser(context);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: const BoxDecoration(
        gradient: LinearGradient(
          begin: Alignment.bottomCenter,
          end: Alignment.topRight,
          colors: [
            Color.fromARGB(255, 0, 27, 48),
            Color.fromARGB(255, 17, 149, 186),
          ],
        ),
      ),
      child: Scaffold(
        backgroundColor: Colors.transparent,
        body: Center(
          child: Image.asset(
            'lib/assets/coin-spin3.gif',
            height: 180,
          ),
        ),
      ),
    );
  }
}

Future<void> checkUser(context) async {
  await Future.delayed(
    const Duration(seconds: 4),
  );
  Navigator.of(context).pushReplacement(
    MaterialPageRoute(
      // builder: (ctx) => const PageOne(),
      builder: (ctx) => const PageOne(),
    ),
  );
}

我的pageOne（启动后的屏幕）代码：

import 'package:flutter/material.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';
import 'package:my_wallet/screens/page_2.dart';

class PageOne extends StatelessWidget {
  const PageOne({Key? key}) : super(key: key);

  @override

          decoration: const BoxDecoration(
            gradient: LinearGradient(
              begin: Alignment.bottomLeft,
              end: Alignment.topRight,
              colors: [
                Color.fromARGB(255, 0, 27, 48),
                Color.fromARGB(255, 17, 149, 186),
              ],
            ),
          ),
