通过MaterialPageRoute布线时未加载颤动页面的数据，但热重新加载正确加载数据？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Home')),
        body: Center(child: ElevatedButton(
          onPressed: () {
            Navigator.of(context).push(MaterialPageRoute(builder: (context) => SecondPage()));
          },
          child: Text('Go to Second Page'),
        )),
      ),
    );
  }
}

class SecondPage extends StatefulWidget {
  @override
  _SecondPageState createState() => _SecondPageState();
}

class _SecondPageState extends State<SecondPage> {
  String _data = '';

  @override
  void initState() {
    super.initState();
    _loadData(); // 确保在initState中调用数据加载方法
  }

  Future<void> _loadData() async {
    // 模拟异步数据加载
    await Future.delayed(Duration(seconds: 2));
    setState(() {
      _data = 'Data loaded successfully';
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Second Page')),
      body: Center(child: Text(_data)),
    );
  }
}
