1. Install get Package
2. Install connectivity_plus Package
3. Create a dart file for connectivity

import 'dart:io';
import 'package:connectivity_plus/connectivity_plus.dart';
import 'package:flutter/material.dart';
import 'package:get/get.dart';

class NetworkController extends GetxController {
  final Connectivity _connectivity = Connectivity();

  @override
  void onInit() {
    super.onInit();
    _connectivity.onConnectivityChanged.listen(_updateConnectionStatus);
  }

    }
  }
}
