Flutter:添加动态TextFormField以将数据上载到列表

import 'package:flutter/material.dart';

class DynamicTextFormField extends StatefulWidget {
  @override
  _DynamicTextFormFieldState createState() => _DynamicTextFormFieldState();
}

class _DynamicTextFormFieldState extends State<DynamicTextFormField> {
  List<String> dataList = []; // 列表变量，用于存储用户输入的数据
  TextEditingController textEditingController = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        ListView.builder(
          shrinkWrap: true,
          itemCount: dataList.length,
          itemBuilder: (context, index) {
            return ListTile(
              title: Text(dataList[index]),
            );
          },
        ),
        TextFormField(
          controller: textEditingController,
          onChanged: (value) {
            setState(() {
              // 更新保存用户输入的变量的值
              textValue = value;
            });
          },
        ),
        RaisedButton(
          onPressed: () {
            setState(() {
              // 将用户输入的值添加到列表变量中
              dataList.add(textEditingController.text);
              textEditingController.clear(); // 清空输入框
            });
          },
          child: Text('提交'),
        ),
      ],
    );
  }
}
