Flutter:如何将Textfield输入放到列表中以构建ListView.builder

import 'package:flutter/material.dart';

class MyWidget extends StatefulWidget {
  @override
  _MyWidgetState createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  List<String> textList = [];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('TextField列表示例'),
      ),
      body: Column(
        children: [
          TextField(
            onChanged: (text) {
              setState(() {
                textList.add(text);
              });
            },
          ),
          Expanded(
            child: ListView.builder(
              itemCount: textList.length,
              itemBuilder: (context, index) {
                return ListTile(
                  title: Text(textList[index]),
                );
              },
            ),
          ),
        ],
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: MyWidget(),
  ));
}
