You can use the wifi package for getting the local IP Address (for eg. 192.168.x.x). (as The NetworkInterface.list (from dart:io) is no longer supporting Android from 7.0 and above).

Use the wifi package :

import 'package:wifi/wifi.dart';

You can retrieve the IP Address like this:

Future getIp() async {
  String ip = await Wifi.ip;
  return ip;
}

You can display it on a Text widget using FutureBuilder:

FutureBuilder(
      future: getIp(),
      builder: (BuildContext context, AsyncSnapshot snapshot) {
        if (snapshot.connectionState == ConnectionState.waiting) {
          return Center(child: CircularProgressIndicator());
        } else {
          if (snapshot.hasError)
            return Center(child: Text('Error: ${snapshot.error}'));
          else
            return Center(child: Text('IP Address is : ${snapshot.data}')); //IP Address
        }
      },
    );
