import 'package:flutter/material.dart';

  @override
  Widget build(BuildContext context) {
    return Container(
      alignment: Alignment.topRight, // 将图像放在角落中
      child: CircleAvatar(
        radius: 50, // 设置圆形图像的半径
        backgroundImage: AssetImage('assets/images/my_image.png'), // 图像资源路径
      ),
    );
  }
}

void main() {

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {

        appBar: AppBar(
          title: Text('My App'),
        ),
        body: MyImageWidget(), // 使用自定义的Widget
