You are adding the multipartFile to request.files outside the for loop. Move it inside...

void uploads() async {
  var uri = Uri.parse(Config.URL + 'Posts/Cube_Post_Submit');
  var request = http.MultipartRequest('POST', uri);
  for (int i = 0; i < image.length; i++) {
    request.files.add(
      http.MultipartFile(
        'attachments$i',
        http.ByteStream(DelegatingStream.typed(image[i].openRead())),
        await image[i].length(),
        filename: basename(image[i].path),
      ),
    );
  }

  request.fields['User_Id'] = Config.USER_ID;
  request.fields['Cubes_Id'] = jsonstring;
  request.fields['Post_Text'] = 'hello';
  request.fields['Post_Category'] = 'Story';
  request.fields['Post_Link'] = '';
  var response = await request.send();
  print(response.statusCode);
  response.stream.transform(utf8.decoder).listen((value) {
    print(value);
  });
}
