悬停按钮上的颤动随机Image.asset变化？

import 'package:flutter/material.dart';
import 'dart:math';

class HoverButton extends StatefulWidget {
  @override
  _HoverButtonState createState() => _HoverButtonState();
}

class _HoverButtonState extends State<HoverButton> {
  List<String> imageAssets = [
    'assets/image1.png',
    'assets/image2.png',
    'assets/image3.png',
    // 添加更多需要展示的图片资源
  ];

  String currentImageAsset = '';

  @override
  Widget build(BuildContext context) {
    return MouseRegion(
      onHover: (event) {
        setState(() {
          currentImageAsset = getRandomImageAsset();
        });
      },
      child: Container(
        padding: EdgeInsets.all(10),
        decoration: BoxDecoration(
          color: Colors.blue,
          borderRadius: BorderRadius.circular(8),
        ),
        child: Image.asset(currentImageAsset),
      ),
    );
  }

  String getRandomImageAsset() {
    Random random = Random();
    int randomIndex = random.nextInt(imageAssets.length);
    return imageAssets[randomIndex];
  }
}

// 使用HoverButton
HoverButton(),
