If you need multipart for file upload, all you have to do is send a FormData object using the HttpRequest class. Example:

import "dart:html";

...

var fileData; //file data to be uploaded

var formData = new FormData();
formData.append("field", "value"); //normal form field
formData.appendBlob("data", fileData); //binary data

HttpRequest.request("/service-url", method: "POST", sendData: formData).then((req) {
  ...
});

Furthermore, if you need to allow the user to upload a file from his hard disk, you have to use a html form with an tag. Example:

Html file:

dart file:

var formData = new FormData(querySelector("#myForm"));
HttpRequest.request("/service-url", method: "POST", sendData: formData).then((req) {
  ...
});
