Expection that I am getting : DioError [DioErrorType.RESPONSE]: Http status error [404]

Answer 1

I added contentType: new MediaType("image", "jpeg")//in the formData. It works now.

Full Code :

import 'package:dio/dio.dart';
import 'package:flutter_project/config/config.dart';
import '../model/postImage.dart';
import 'dart:io';
import 'package:http/http.dart' as http;
import 'package:http_parser/http_parser.dart';

Future<PostImage> postImage(File image) async {
  String fileName = image.path.split('/').last;
  print(fileName);

  try {
    Dio dio = new Dio();
    FormData formData = FormData.fromMap({
      "file": await MultipartFile.fromFile(
        image.path,
        filename: fileName,
        contentType: new MediaType("image", "jpeg"),
      )
    });
    Map<String, String> headers = <String, String>{
      'Content-Type': 'multipart/form-data'
    };
    print("${baseURL}files/upload");
    Response response =
        await dio.post("${baseURL}files/upload", data: formData);
    if (response.statusCode == 200) {
      print("Uploaded");
    } else {
      print(response.data);
    }
    print('Out');
  } catch (e) {
    print(e);
  }
}
