如何在flutter中创建SimpleDialog控件的动态内容的最佳实践？

import 'package:flutter/material.dart';

class DynamicContentDialog extends StatefulWidget {
  @override
  _DynamicContentDialogState createState() => _DynamicContentDialogState();
}

class _DynamicContentDialogState extends State<DynamicContentDialog> {
  String dynamicContent = 'Initial Content';

  @override
  Widget build(BuildContext context) {
    return SimpleDialog(
      title: Text('Dynamic Content Dialog'),
      children: [
        Text(dynamicContent),
        RaisedButton(
          child: Text('Change Content'),
          onPressed: () {
            setState(() {
              dynamicContent = 'New Content';
            });
          },
        ),
      ],
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        title: Text('Flutter SimpleDialog Example'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Open Dialog'),
          onPressed: () {
            showDialog(
              context: context,
              builder: (BuildContext context) {
                return DynamicContentDialog();
              },
            );
          },
        ),
      ),
    ),
  ));
}
