如何将控件动态添加到Flutter中的列？

import 'package:flutter/material.dart';

List<Widget> dynamicWidgets = [];

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text('动态添加控件示例'),
    ),
    body: ListView.builder(
      itemCount: dynamicWidgets.length,
      itemBuilder: (context, index) {
        return dynamicWidgets[index];
      },
    ),
    floatingActionButton: FloatingActionButton(
      onPressed: () {
        // 添加控件到列
        setState(() {
          dynamicWidgets.add(
            Text('动态添加的控件 ${dynamicWidgets.length + 1}'),
          );
        });
      },
      child: Icon(Icons.add),
    ),
  );
}
