http.post does not return

[shtengel]

i wrote it here: https://stackoverflow.com/questions/52552002/flutter-http-post-never-returns-a-response

but TLDR;

  print("before");
  http.Response res = await http.post(url, body:data);
  print("after");

code never reaches the print("after");
but my server does get the HTTP POST request..

please help me

What happens if you access the same URL with wget or curl?
