ping_discover_network 0.1.1

Library that allows to ping IP subnet and discover network devices. Could be used to find printers and other devices and services in a local network.

ping_discover_network

Dart/Flutter library that allows to ping IP subnet and discover network devices.

Could be used to find printers (for example, on port 9100) and any other devices and services in local network.

The device should be connected to a Wi-Fi network. wifi package allows to get the local IP address / network subnet.

The library tested on both, Android and iOS platforms.

Getting Started

Discover available network devices in a given subnet on a given port:

import 'package:ping_discover_network/ping_discover_network.dart';

final stream = NetworkAnalyzer.discover('192.168.0', 9100);

stream.listen((NetworkAddress addr) {
  if (addr.exists) {
      print('Found device: ${addr.ip}');
    }
  }).onDone(() => print('Finish'));

Discover available network devices in a given subnet on a given port range:

import 'package:ping_discover_network/ping_discover_network.dart';

void checkPortRange(String subnet, int fromPort, int toPort) {
  if (fromPort > toPort) {
    return;
  }

  print('port ${fromPort}');

  final stream = NetworkAnalyzer.discover(subnet, fromPort);

  stream.listen((NetworkAddress addr) {
    if (addr.exists) {
      print('Found device: ${addr.ip}:${fromPort}');
    }
  }).onDone(() {
    checkPortRange(subnet, fromPort + 1, toPort);
  });
}

checkPortRange('192.168.0', 400, 410);

Todo

• Add Flutter app example: get the local ip and ping the subnet
• Ping addresses one by one with a short timeout
