Please try this

       Future<dynamic> _upload() async {
            if (file == null) return;
            String fileName = file.path.split('/').last;
            Map<String, dynamic> formData = {
              "image": await MultipartFile.fromFile(file.path,filename: fileName),
            };
           return await Dio()
        .post(url,data:formData).
    then((dynamic result){
    print(result.toString());
});
}
