Dart / Flutter package that allows discovering network devices in local network (LAN) via multi-threaded ICMP pings.

Note: This library is intended to be used on Class C networks.

pub.dev page | API reference

Getting Started #

Add the package to your pubspec.yaml:

lan_scanner: ^4.0.0

Import the library:

import 'package:lan_scanner/lan_scanner.dart';

Create an instance of the class and call quickIcmpScanAsync() on it:

final scanner = LanScanner();

final List<Host> hosts = scanner.quickIcmpScanAsync('192.168.0');

There is also stream-based icmpScan() method available, which provides progress callback, but is much slower and resource hungry than other methods.

If you don't know what subnet to provide, you can use network_info_plus to get your local IP and then ipToCSubnet() function, which will conviently strip the last octet of the IP address:

// 192.168.0.1
var wifiIP = await NetworkInfo().getWifiIP()

// 192.168.0
var subnet = ipToCSubnet(wifiIP);

iOS compatibility #

Due to the issue with Flutter platform channels (#119207), iOS platform is currently supported only when using the quickIcmpScanSync() method and requires additional steps:

Add dart_ping_ios to your pubspec.yaml:

dart_ping_ios: ^4.0.0

Call register() method before running your app:

void main() {
  DartPingIOS.register();

  runApp(const App());
}
