How to get tracking number and its title(FEDEX) for each item in Magento 2

Question

I need to get a tracking number which resides in sales_shipment_track for each item in an order. Right now I am iterating all items of an order.

foreach ($_order->getAllItems() as $item) {
  echo $item->getTrackNumber();
}

This didnt work. How to get a tracking number and its title i.e, FEDEX so that I can know which carrier is that tracking number.

Answer 1

         $tracksCollection = $order->getTracksCollection();

        foreach ($tracksCollection->getItems() as $item) {

          echo $track->getTrackNumber(); // Tracking number

             }
