Flutter: Connection closed while receiving data

Question

I'm calling post API, and sometimes I get the response from the server and sometimes I receive the exception Connection closed while receiving data. Request is same in both cases, and according to backend server logs, a response is sent but i didn't receive it. I have this issue both in simulator and actual device.

try {
  final result =
      await http.post(url, body: encodedBody, headers: apiHeader);
  Map<String, dynamic> response = json.decode(result.body);

  print("Response: $response");

  return response;
} catch (error) {
  Map<String, dynamic> response = Map<String, dynamic>();
  response['success'] = false;
  response['message'] = error;
  return response;
}

Answer 1

Keep-Alive header in the headers of your request might be missing, please check with APIs required headers

Answer 2

I had the issue with a get request, sometimes I get the response from the server and sometimes I receive the exception Connection closed while receiving data on same button click event. Then I founded that the number of records of particular table in database is quite large. My suggested solution is to use pagination in the backend server.
