Can't catch SocketException

[carlhung]

Exception has occurred.
SocketException (SocketException: OS Error: Connection timed out, errno = 110, address = carlhung.mynetgear.com, port = 45396)

I can catch the returned result. but after a while, the simulator of android will crash with SocketException. my code:

    try {
      request = await Requests.post(
        url + '/login',
        headers: {'content-type': 'application/json'},
        json: dic,
        verify: false,
        // timeoutSeconds: 5,
      );
    } catch (e) {
      return {"result":"Connection Error: $e"}; 
    }

do you have the stacktrace of where the exception is thrown?

please check in all places you call Requests that you are using await, if not it will cause this behavior https://github.com/dart-lang/http/issues/160

I encounter the problem is more like that: https://stackoverflow.com/questions/57182940/unhandled-socket-exception-with-no-internet-connection-when-i-set-timeout-durati

can catch the timeoutException error. then, it will be returned. but after 15-20 sec, it throws socketException.

so, it throws twice. the first exception will be caught.

I am using gsheets api to access a gsheet in my drive. i thought that when the internet is turned off then a pop up would appear on accessingvthe gsheet but am not able to handle the SocketException. https://github.com/dart-lang/http/issues/160 Some peopke have this issue but mine is still unresolved

Hello, I experience the exact same behavior. I use

import 'package:http/http.dart' as http;
import 'dart:io';

and when

http.Response response = await _client
          .get(dataURL, headers: _standardHeaders)
          .timeout(const Duration(seconds: 20));

runs into a timeout because the server is down

    } on SocketException catch (e) {
      return (Left(e));
    } catch (e) {
      return (Left(e));
    }

catches the timeout exception first, what is perfect!

But then, after some time the client throws

Exception has occurred.
SocketException (SocketException: OS Error: Connection timed out, errno = 110, address = 192.168.178.62, port = 44850)

in io_client.dart at

var ioRequest = (await _inner.openUrl(request.method, request.url))

This is not catched. The Client (Android Emulator) crashes and code execution stops.
