this is my upload function

void upload() async {
    print("inside upload image");
    if (file == null) return;
    String base64 = base64Encode(file.readAsBytesSync());
    String imagename = file.path.split("/").last;
    dynamic data = {"imagename": imagename, "image64": base64};
    var url = "http://waaasil.com/care/api/saveProfileImage";

    try {
      response1 = Dio().post(
        "***********************",
        data: data,
        options: Options(
            followRedirects: false,
            validateStatus: (status) {
              return status < 500;
            }),
      );
     
    } on DioError catch (e, s) {
      print("what happend  when upload image   ? :    "   e.toString());
    }
   

   
  }

String imageName = file.path.split('/').last;

    FormData data = FormData.fromMap({
      "imagename": await MultipartFile.fromFile(
        file.path, filename: imageName),
    });

    Dio dio = new Dio();

    dio.options.connectTimeout =(60*1000); 
    dio.options.receiveTimeout= (60*1000);


    dio.post("http://waaasil.com/care/api/saveProfileImage", data: data,
        options: Options(
            followRedirects:false,
            validateStatus: (status)=> return status < 500,
        )).then((response) {
      
      if(response.statusCode==200){
        // response good
      }
      else //Something went wrong

If you have token(bearer token) then pass it on header

error 500 means Internal Server Error in this case you need to talk with the backend to send you a valid documentation how to use the API is it multipart or JSON, post or put ... etc
