如何在页面类型转换中访问小部件的属性

import 'package:flutter/material.dart';

class MyWidget extends StatefulWidget {
  final String title;
  final int count;

  MyWidget({required this.title, required this.count});

  @override
  _MyWidgetState createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Text('Count: ${widget.count}'),
      ),
    );
  }
}
