Network Tools Flutter package

Please check network_tools_flutter package for extensive support to features on different platforms.

Import package in your app

import 'package:network_tools/network_tools.dart';

Configure network tools in main function

For dart native

Future<void> main() async {
  await configureNetworkTools('build', enableDebugging: true);
  runApp(const MyApp());
}

For flutter apps

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  // It's necessary to pass correct path to be able to use this library.
  final appDocDirectory = await getApplicationDocumentsDirectory();
  await configureNetworkTools(appDocDirectory.path, enableDebugging: true);
  runApp(const MyApp());
}

Usage

Host Scanner

 String address = '192.168.1.12';
  // or You can also get address using network_info_plus package
  // final String? address = await (NetworkInfo().getWifiIP());
  final String subnet = address.substring(0, address.lastIndexOf('.'));
  final stream = HostScannerService.instance.getAllPingableDevices(subnet, firstHostId: 1, lastHostId: 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';
  PortScannerService.instance.scanPortsForSingleDevice(target, startPort: 1, endPort: 1024,
      progressCallback: (progress) {
    print('Progress for port discovery : $progress');
  }).listen((ActiveHost event) {
    if (event.openPorts.isNotEmpty) {
      print('Found open ports : ${event.openPorts}');
    }
  }, onDone: () {
    print('Scan completed');
  });
  //2. Single
  bool isOpen = (await PortScanner.isOpen(target, 80)) == null;
  //3. Custom
  PortScanner.customDiscover(target, portList: const [22, 80, 139]);

Mdns Scanner

  for (final ActiveHost activeHost in await MdnsScannerService.instance.searchMdnsDevices()) {
    final MdnsInfo? mdnsInfo = await activeHost.mdnsInfo;
    print('''
    Address: ${activeHost.address}
    Port: ${mdnsInfo!.mdnsPort}
    ServiceType: ${mdnsInfo.mdnsServiceType}
    MdnsName: ${mdnsInfo.getOnlyTheStartOfMdnsName()}
    ''');
  }
