Description

This is happening on real device (iPhone 11) On my app, in an on click event, i am trying to get some data from api. Before that i am checking internet connectivity. When i’m using this

import NetInfo from "@react-native-community/netinfo";

NetInfo.fetch().then(internetState => {
  console.log(internetState);
  if (internetState.isConnected && internetState.isInternetReachable) {
    // rest of my code
  }else{
    // some warning
  }
});

on first attempt it is returning this, with isInternetReachable is returning null. LOG {“details”: {“bssid”: null, “ipAddress”: “192.168.1.2”, “isConnectionExpensive”: false, “ssid”: null, “subnet”: “255.255.255.0”}, “isConnected”: true, “isInternetReachable”: null, “type”: “wifi”}

but if i click the button again, now isInternetReachable is returning true LOG {“details”: {“bssid”: null, “ipAddress”: “192.168.1.2”, “isConnectionExpensive”: false, “ssid”: null, “subnet”: “255.255.255.0”}, “isConnected”: true, “isInternetReachable”: true, “type”: “wifi”}

Its only happening on ios. any idea guys?
