I am not able to upload images and form data to rest api using DIO package in flutter - flutter

Question

I am not able to upload image to rest api in flutter I have checked the api its working fine.
I am not able to convert the file (image) to a uploadable form, can any one help me with that?
I have run flutter doctor -v everything is fine :)
Here is the code I am using to post form data:
Future<void> uploadAccountDetails(AccountDetailsModel details) async {
var url = baseUrl + '/api/uploads/images';
try {
Dio dio = new Dio();
FormData formData = new FormData.fromMap(
{
'city': details.cityName,
'country': details.countryName,
'residence_address': details.address,
'dob': details.dob,
'id_num': details.id,
'passport_num': details.passportNo,
'driving_license_nim': details.drivingLicNo,
'user_id': 162,
'postal_code': details.postalCode,
'id_pic': await MultipartFile.fromFile(details.idPic.path,
filename: basename(details.idPic.path)),
'driving_license_pic':
await MultipartFile.fromFile(details.drivingLicPic.path,
filename: basename(
details.drivingLicPic.path,
)),
'birth_certificate': await MultipartFile.fromFile(
details.drivingLicPic.path,
filename: basename(details.birthCertPic.path),
),
'residence_permit_pic': await MultipartFile.fromFile(
details.resPermitPic.path,
filename: basename(details.resPermitPic.path),
),
'profile_pic': await MultipartFile.fromFile(details.profilePic.path,
filename: basename(details.profilePic.path)),
},
);
print(formData);
Response response = await dio.post(
url,
data: formData,
onSendProgress: (received, total) {
if (total != -1) {
print((received / total * 100).toStringAsFixed(0) + "%");
}
},
);
print(response.statusCode);
// print(response);
} catch (e) {
print(e);
throw (e);
}
}
The logs of error are as follows:
I/flutter (22523): DioError [DioErrorType.RESPONSE]: Http status error
[500] I/flutter (22523): DioError [DioErrorType.RESPONSE]: Http status
error [500]
The status error is:
I/flutter (22523): DioError [DioErrorType.RESPONSE]: Http status error
[500]
I searched this error but didnt find any solution, can anyone help me with that?

I used dio for post a file path with some other information in this way:
Dio dio = new Dio();
FormData formData = new FormData();
formData.add(
"apiKey",
"my_api_key",
);
formData.add(
"file",
"image_path",
);
Response response = await dio.post(
"https://localhost",
data: formData,
onSendProgress: (int sent, int total) {
// do something
},
).catchError((onError) {
throw Exception('something');
});
