如何在flutter中在屏幕上显示来自get请求的图像？

import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'dart:typed_data';

Future<Uint8List> fetchImage() async {
  final response = await http.get(Uri.parse('https://example.com/image.jpg'));
  if (response.statusCode == 200) {
    return response.bodyBytes;
  } else {
    throw Exception('Failed to load image');
  }
}

class ImageScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Image from GET Request'),
      ),
      body: FutureBuilder<Uint8List>(
        future: fetchImage(),
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting) {
            return Center(child: CircularProgressIndicator());
          } else if (snapshot.hasError) {
            return Center(child: Text('Error: ${snapshot.error}'));
          } else {
            return Center(
              child: Image.memory(snapshot.data),
            );
          }
        },
      ),
    );
  }
}
