Set timeout for HTTPClient get() request

Question

This method submits a simple HTTP request and calls a success or error callback just fine:

  void _getSimpleReply( String command, callback, errorCallback ) async {

    try {

      HttpClientRequest request = await _myClient.get( _serverIPAddress, _serverPort, '/' );

      HttpClientResponse response = await request.close();

      response.transform( utf8.decoder ).listen( (onData) { callback( onData ); } );

    } on SocketException catch( e ) {

      errorCallback( e.toString() );

    }
  }

If the server isn't running, the Android-app more or less instantly calls the errorCallback.

On iOS, the errorCallback takes a very long period of time - more than 20 seconds - until any callback gets called.

May I set for HttpClient() a maximum number of seconds to wait for the server side to return a reply - if any?

You can use timeout

http.get(Uri.parse('url')).timeout(
  const Duration(seconds: 1),
  onTimeout: () {
    // Time has run out, do what you wanted to do.
    return http.Response('Error', 408); // Request Timeout response status code
  },
);
