you need to annotate your post request with @Multipart and pass MultipartBody.Part in your createEditObject method like that.

@Multipart
@POST("/my-api")
fun createEditObject(@Body requestMap: HashMap<String, Any?>, @Part file: MultipartBody.Part): Call<Object>

now you can create your file parameter like that.

val file = File(filePath)
val reqBody = RequestBody.create(MediaType.parse("image/jpeg"), file)
val part = MultipartBody.Part.createFormData(NAME, FILE_NAME, reqBody)

how can I upload files by multipart using retrofit with the other keys?
