ping_discover_network 0.0.2

The library allows to ping IP subnet and therefore discover network devices. Could be used to find printers (for example, on port 9100) and other services in local network.

ping_discover_network

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

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

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(() {
    if (fromPort + 1 <= toPort) {
      checkPortRange(subnet, fromPort + 1, toPort);
    }
  });
}

checkPortRange('192.168.0', 400, 410);
