Mdns Scanner

Import package in your app

import 'package:network_tools/network_tools.dart';

Usage

Host Scanner

 String ip = '192.168.1.12';
  // or You can also get ip using network_info_plus package
  // final String? ip = await (NetworkInfo().getWifiIP());
  final String subnet = ip.substring(0, ip.lastIndexOf('.'));
  final stream = HostScanner.discover(subnet, firstSubnet: 1, lastSubnet: 50,
      progressCallback: (progress) {
    print('Progress for host discovery : $progress');
  });

  stream.listen((host) {
    //Same host can be emitted multiple times
    //Use Set<ActiveHost> instead of List<ActiveHost>
    print('Found device: ${host}');
  }, onDone: () {
    print('Scan completed');
  }); // Don't forget to cancel the stream when not in use.

Port Scanner

    //1. Range
    String target = '192.168.1.1';
    PortScanner.discover(target, startPort: 1, endPort: 1024,
      progressCallback: (progress) {
    print('Progress for port discovery : $progress');
    }).listen((event) {
    if (event.isOpen) {
      print('Found open port : $event');
    }
    }, onDone: () {
    print('Scan completed');
    });
    //2. Single
    bool isOpen = PortScanner.isOpen(target,80);
    //3. Custom
    PortScanner.customDiscover(target, portList : const [22, 80, 139]);

Mdns Scanner

    for (final ActiveHost activeHost in await MdnsScanner.searchMdnsDevices()) {
      final MdnsInfo? mdnsInfo = activeHost.mdnsInfo;
      print(
        'IP: ${activeHost.ip}, Port: ${mdnsInfo!.mdnsPort}, ServiceType: ${mdnsInfo.mdnsServiceType}, MdnsName: ${mdnsInfo.getOnlyTheStartOfMdnsName()}',
      );
    }

Enable Debugging

Add this code to your main.dart file

    Logger.root.level = Level.FINE; //set to finest for detailed log
      Logger.root.onRecord.listen((record) {
        print(
            '${DateFormat.Hms().format(record.time)}: ${record.level.name}: ${record.loggerName}: ${record.message}');
      });
