MultipartRequest class

A multipart/form-data request. Such a request has both string fields, which function as normal form fields, and (potentially streamed) binary files.

This request automatically sets the Content-Type header to multipart/form-data. This value will override any value set by the user.

var uri = Uri.parse("");
var request = new http.MultipartRequest("POST", uri);
request.fields['user'] = '';
request.files.add(new http.MultipartFile.fromPath(
    contentType: new MediaType('application', 'x-tar'));
var response = await request.send();
if (response.statusCode == 200) print('Uploaded!');
