how to send image to server with other data in formdata in flutter

is there any mistake while sending the data?

Image path is received correctly however the image is mandatory and not uploading

import 'dart:developer';
import 'dart:io';
import 'package:dio/dio.dart';

import 'package:real_estate_app/domain/core/api_end_points.dart';

class APIAddService {
  static final Dio _dio = Dio();

  static Future<void> addProperty({
    required String accessToken,
    required String propName,
    required String propPrice,
    required String propAge,
    required int propStatus,
    required int propType,
    required String location,
    required int availabilityStatus,
    required List<String> spec,
    required List<String> size,
    required List<File> image,
  }) async {
    try {
      String apiUrl = ApiEndPoints.addproperty;

      List<MultipartFile> imageFiles = [];
      for (File img in image) {
        imageFiles.add(await MultipartFile.fromFile(
          img.path,
          filename: img.path.split('/').last,
        ));
      }

      FormData formData = FormData.fromMap({
        "prop_name": propName,
        "prop_price": propPrice,
        "prop_status": propStatus,
        "prop_type": propType,
        "prop_age": propAge,
        "location": location,
        "availability_status": availabilityStatus,
        "spec": spec,
        "size": size,
        "image": imageFiles,
      });
      log('imageFiles:$imageFiles');
      log('images: ${image.map((file) => file.path).toList()}');
      log('FormData: $formData');
      log('formfields:${formData.fields}');
      
      Options options = Options(headers: {
        "access-token": accessToken,
      });

      Response response = await _dio.post(
        apiUrl,
        data: formData,
        options: options,
      );

      print("Response status code: ${response.statusCode}");
      print("Response data: ${response.data}");

      if (response.statusCode == 200 && response.data['responseCode'] == 200) {
        print("Property added successfully!");
      } else {
        print("Failed to add property. Response data: ${response.data}");
      }
    } catch (e) {
      if (e is DioException) {
        print("Dio Error: ${e.message}");
        print("Dio Error Response: ${e.response?.data}");
      } else {
        print("Error: $e");
      }
    }
  }
}

what is the right way to do it? I used the image_picker package to select multiple images, and then utilized Dio for sending server requests to upload them.

you missed to specify the content type ,use below snippet instead

List<MultipartFile> imageFiles = [];
      for (File img in image) {
        String fileName = basename(img.path);
        String fileExtension = extension(fileName).substring(1);
        imageFiles.add(await MultipartFile.fromFile(
          img.path,
          contentType: MediaType('image', fileExtension),
          filename: fileName,
        ));
      }
