Flutter: How to get upload / download progress for http requests

Question

I am writing an app that uploads an image to a server, and instead of just showing a spinner, I\'d love to be able to get progress on the status of that upload.

Try dio library. The onSendProgress callback would be helpful.

example:

response = await dio.post(
  "http://www.example.com",
  data: data,
  onSendProgress: (int sent, int total) {
    print("$sent $total");
  },
);
