Choose a file (image, pdf, doc) and upload to server flutter android - flutter

Question

I'm working with ASP.NET rest APIs. The task is I have to choose only one thing i.e image, pdf, docs file and send it to server. For picking files, I'm using the following library
file_picker: ^3.0.3
After successfully picking the file when I send it to the server, the response from the server is 403 forbidden.
// this is picking image code
ElevatedButton(
onPressed: () async {
FilePickerResult result = await FilePicker.platform.pickFiles();
if (result != null) {
PlatformFile file = result.files.first;
ApiClient.apiClient.uploadDocumentApi(file.path);
}
},
style: ElevatedButton.styleFrom(
primary: kPrimaryColor,
elevation: 0.0,
),
child: Text('Select'),
),
// this is API code
Future<void> uploadDocumentApi(String filePath) async {
print('pathh: ' + filePath);
String url = 'www.example.com';
var request = http.MultipartRequest(
'POST',
Uri.parse(url),
);
// request.files.add(await http.MultipartFile.fromPath('', filePath));
request.files.add(
http.MultipartFile(
'',
File(filePath).readAsBytes().asStream(),
File(filePath).lengthSync(),
filename: filePath.split("/").last,
),
);
http.StreamedResponse response = await request.send();
print(response.statusCode);
print(response.reasonPhrase);
if (response.statusCode == 200) {
print('success');
print(response.stream.bytesToString());
} else {
print('fail');
print(response.reasonPhrase);
}
}

As the error code indicates its related to authentication of your request. make sure your set your jwt correctly in your request header if needed and check it with backend side
