Ping on relase

[MarcuzziGiuseppe]

I've tryed to do a ping and compile my app in release mode using this code:

final result = await Ping(ipServer, count: 1).stream.first;
    if (result.error != null || result.response == null) {
      return false;
    } else if (result.response != null || result.error == null) {
      return true;
    }

but it return this error:
E/flutter (14799): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Bad state: No element
E/flutter (14799): #0 Stream.first. (dart:async/stream.dart:1575)

E/flutter (14799): #9 _startMicrotaskLoop (dart:async/schedule_microtask.dart:49)
