Is there any way to ping a server to find the latency between device and server in miliseconds - dart/flutter

Question

I have created two dropdown boxes one selects game and other servers. image of app

All i want to do is to know if there is a way to ping a server and get the latency, probably something like this in dart/flutter.

Edit: just installed the dart_ping lib and ran this code.

  void main() {
    runApp(const MyApp());
    pingIt();
  }

void pingIt() {
  var ping = Ping('google.com', count: 5);
  print('Running command: ${ping.command}');
  ping.stream.listen((event) {
    print("response : $event");
  });
  print("$ping");
}

It runs without any error, but the console says there are no responses from the server.

    I/flutter (13831): Running command: ping -O -n -W 2 -i 1 -t 255 -c 5 google.com
I/flutter (13831): Instance of 'PingLinux'.
I/flutter (13831): response : PingError(response:PingResponse(seq:1), error:RequestTimedOut)
I/flutter (13831): response : PingError(response:PingResponse(seq:2), error:RequestTimedOut)
I/flutter (13831): response : PingError(response:PingResponse(seq:3), error:RequestTimedOut)
I/flutter (13831): response : PingError(response:PingResponse(seq:4), error:RequestTimedOut)
I/flutter (13831): response : PingSummary(transmitted:5, received:0), time: 4102 ms, Errors: [RequestTimedOut, RequestTimedOut, RequestTimedOut, RequestTimedOut, NoReply]

So what should i do now and how can i know how many responses were received and how many were lost. How do i actually get ping does the lib contain a method that returns the ping or is there another way to do so.

By the way, I'm testing it in an android emulator.

Did you try the obvious [dart_ping](https://pub.dev/packages/dart_ping)? — nvoigt, Dec 20 '21 at 17:54
@nvoigt just tried dart_ping, but it shows error in console. I edited the question. — iw2d, Dec 20 '21 at 21:33

If you are using Android Emulator to test this code then, you need to know that you can not ping from android emulatorcheck here. Use phisical device to test it.

Latest version of dart_ping works. I have tested it on physical android device with google.com, works as expected.
