A Flutter package that allows discovering network devices in local network

lan_scanner

dart / flutter package that allows discovering network devices in local network (lan).

note: this library is intended to be used on class c networks.

this project is a rework of already existing ping_discover_network, however it is no longer maintained.

getting started

add the package to your pubspec.yaml:

lan_scanner: ^2.0.0

import the library:

import 'package:lan_scanner/lan_scanner.dart';

create an instance of the class and call
quickscan() or precisescan() on it:

final port = 80;
final subnet = "192.168.0";
final timeout = duration(seconds: 5);

final scanner = lanscanner();

final stream = scanner.precisescan(
    subnet,
    timeout: timeout,
    progresscallback: (progressmodel progress) {
        print('${progress.percent * 100}% 192.168.0.${progress.currip}');
    },
);

stream.listen((devicemodel device) {
    if (device.exists) {
        print("found device on ${device.ip}:${device.port}");
    }
});

if you don’t know what is your subnet, you can use network_info_plus and then iptosubnet() function.

var wifiip = await (networkinfo().getwifiip())

var subnet = iptosubnet(wifiip);
