  Utility method that calls a callback whenever the network connectivity of the app changes.
  The callback should take a boolean parameter (with `true` meaning
  the network is offline, and `false` meaning online)

  Example:

      import { installOfflineWatcher } from 'pwa-helpers/network.js';

      installOfflineWatcher((offline) => {
        console.log('You are ' + offline ? ' offline' : 'online');
      });
*/
export declare const installOfflineWatcher: (offlineUpdatedCallback: (isOffline: boolean) => void) => void;
