Support for non-stream single ping

[r3a1d3a1]

Hello,

It'd be great not to rely on a stream if one needs to do a single Ping.

Thank you!

You can just grab the first ping like this:

import 'package:dart_ping/dart_ping.dart';

void main() async {
  // Create ping object with desired args
  final ping = Ping('google.com', count: 1);
  final result = await ping.stream.first;
}

Even shorter: final result = await Ping('google.com', count: 1).stream.first;

That's good enough for me; Thank you!

I've added this to the documentation for the future. Thanks
