当onTap所有的图标都改变颜色时，如何让它在点击时只改变一个？

import 'package:flutter/material.dart';

class IconColorChange extends StatefulWidget {
  @override
  _IconColorChangeState createState() => _IconColorChangeState();
}

class _IconColorChangeState extends State<IconColorChange> {
  List<bool> iconColors = [false, false, false]; // 初始状态为false，表示未点击

  void changeIconColor(int index) {
    setState(() {
      // 将点击的图标颜色状态设置为true，其他图标颜色状态设置为false
      for (int i = 0; i < iconColors.length; i++) {
        if (i == index) {
          iconColors[i] = true;
        } else {
          iconColors[i] = false;
        }
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        GestureDetector(
          onTap: () => changeIconColor(0),
          child: Icon(
            Icons.home,
            color: iconColors[0] ? Colors.blue : Colors.black, // 根据颜色状态设置不同的颜色
          ),
        ),
        GestureDetector(
          onTap: () => changeIconColor(1),
          child: Icon(
            Icons.settings,
            color: iconColors[1] ? Colors.blue : Colors.black,
          ),
        ),
        GestureDetector(
          onTap: () => changeIconColor(2),
          child: Icon(
            Icons.person,
            color: iconColors[2] ? Colors.blue : Colors.black,
          ),
        ),
      ],
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        title: Text('Icon Color Change'),
      ),
      body: Center(
        child: IconColorChange(),
      ),
    ),
  ));
}
