                        <span class="details">
                            <span class="label label-sm label-icon label-success">
                                <i class="fa fa-plus"></i>
                        </span> {{$users->title}} </span>
                    </a>
                </li>
                @endforeach
            </ul>
        </li>
    </ul>
</li>

Route is as

Route::any('/notification', ['as' => 'user.notification', 'uses' => 'NotificationController@getNotificationsView']);

It gives "Error: undefined variable notifications"

You're not passing any variables to the view. Do this:

public function getNotificationsView()
{
    $notifications = UserNotifications::orderBy('id', 'desc')->get();
    return view('notifications', compact('notifications'));
}

Or:

public function getNotificationsView()
{
    $notifications = UserNotifications::orderBy('id', 'desc')->get();
    return view('notifications', ['notifiactions' => $notifications]);
}
