Getting Started

Add the package to your pubspec.yaml:

lan_scanner: ^3.5.0

Import the library:

import 'package:lan_scanner/lan_scanner.dart';

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

final scanner = LanScanner();

final stream = scanner.icmpScan('192.168.0', progressCallback: (progress) {
    print('Progress: $progress');
});

stream.listen((HostModel device) {
    print("Found host: ${device.ip}");
});

If you don't know what is your subnet, you can use network_info_plus and then ipToCSubnet() function.

var wifiIP = await NetworkInfo().getWifiIP()

var subnet = ipToCSubnet(wifiIP);
