如何将Image实例转换为在Flutter中具有路径的File？

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

Future<Uint8List> loadImageBytes(String imageUrl) async {
  final response = await http.get(Uri.parse(imageUrl));
  return response.bodyBytes;
}

Uint8List imageBytes = await loadImageBytes('https://example.com/image.jpg');

import 'package:path_provider/path_provider.dart';

Directory appDocumentsDirectory = await getApplicationDocumentsDirectory();

import 'dart:io';

File imageFile = File('${appDocumentsDirectory.path}/image.jpg');
await imageFile.writeAsBytes(imageBytes);
