如何在flutter中点击并上传多张图片

import 'package:image_picker/image_picker.dart';

Future<List<String>> pickAndUploadImages() async {
  List<String> uploadedImageUrls = [];
  
  // 选择多张图片
  List<XFile>? images = await ImagePicker().pickMultiImage();
  
  // 上传图片
  for (XFile image in images!) {
    // 将图片上传到服务器，并获取上传后的图片URL
    String imageUrl = await uploadImageToServer(image.path);
    uploadedImageUrls.add(imageUrl);
  }
  
  return uploadedImageUrls;
}

Future<String> uploadImageToServer(String imagePath) async {
  // 构建上传请求
  FormData formData = FormData.fromMap({
    'image': await MultipartFile.fromFile(imagePath),
  });
  
  // 发送上传请求
  Response response = await Dio().post('your_upload_url', data: formData);
  
  // 解析服务器返回的图片URL
  String imageUrl = response.data['url'];
  
  return imageUrl;
}

List<String> uploadedImageUrls = await pickAndUploadImages();
// 处理上传后的图片URL
