如何使用flutter更改列表视图项目中具有不同按钮的文本的颜色

import 'package:flutter/material.dart';

class ListItemModel {
  String text;
  Color textColor;
  bool isButtonPressed;

  ListItemModel({this.text, this.textColor, this.isButtonPressed = false});
}

class MyListView extends StatefulWidget {
  @override
  _MyListViewState createState() => _MyListViewState();
}

class _MyListViewState extends State<MyListView> {
  List<ListItemModel> items = [
    ListItemModel(text: 'Item 1', textColor: Colors.black),
    ListItemModel(text: 'Item 2', textColor: Colors.black),
    ListItemModel(text: 'Item 3', textColor: Colors.black),
  ];

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: items.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(
            items[index].text,
            style: TextStyle(color: items[index].textColor),
          ),
          trailing: RaisedButton(
            onPressed: () {
              setState(() {
                items[index].isButtonPressed = !items[index].isButtonPressed;
                items[index].textColor =
                    items[index].isButtonPressed ? Colors.red : Colors.black;
              });
            },
            child: Text('Button'),
          ),
        );
      },
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        title: Text('Flutter ListView'),
      ),
      body: MyListView(),
    ),
  ));
}
