void uploadFile(File file) async {
// string to uri
var uri = Uri.parse("enter here upload URL");
// create multipart request
var request = new http.MultipartRequest("POST", uri);
// if you need more parameters to parse, add those like this. i added "user_id". here this "user_id" is a key of the API request
request.fields["user_id"] = "text";
// multipart that takes file.. here this "idDocumentOne_1" is a key of the API request
MultipartFile multipartFile = await http.MultipartFile.fromPath(
'idDocumentOne_1',
file.path
);
// add file to multipart
request.files.add(multipartFile);
// send request to upload file
await request.send().then((response) async {
// listen for response
response.stream.transform(utf8.decoder).listen((value) {
print(value);
});
}).catchError((e) {
print(e);

I used file picker to pick file.
Here is the codes for pick file.
Future getPdfAndUpload(int position) async {
File file = await FilePicker.getFile(
type: FileType.custom,
allowedExtensions: ['pdf','docx'],
);
if(file != null) {
setState(() {
file1 = file; //file1 is a global variable which i created
});
}
}
here file_picker flutter library.
