如何将Future<dynamic>转换为图像？

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

Future<Uint8List> getImageData() async {
  // 使用http库发送网络请求获取图像数据
  var 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 FutureBuilder<Uint8List>(
      future: getImageData(),
      builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.done &&
            snapshot.hasData) {
          // 解析图像数据为Image对象
          var image = Image.memory(snapshot.data!);
          return Scaffold(
            body: Center(child: image),
          );
        } else if (snapshot.hasError) {
          return Scaffold(
            body: Center(child: Text('Error: ${snapshot.error}')),
          );
        } else {
          return Scaffold(
            body: Center(child: CircularProgressIndicator()),
          );
        }
      },
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: ImageScreen(),
  ));
}
