Unable to get cart item in custom phtml – Magento 2

I am trying to get cart items info in my module’s phtml file:

/app/code/Essence/Fcf/view/frontend/templates/packages.phtml 

Here is my working url: http://essence.onlineprojectprogress.com/packages

And this is my code:

<?php     $  cart = $  objectManager->get('\Magento\Checkout\Model\Cart');       // retrieve quote items collection     $  itemsCollection = $  cart->getQuote()->getItemsCollection();      // get array of all items what can be display directly     $  itemsVisible = $  cart->getQuote()->getAllVisibleItems();      // retrieve quote items array     $  items = $  cart->getQuote()->getAllItems();      foreach($  items as $  item) {         echo 'ID: '.$  item->getProductId().'<br />';         echo 'Name: '.$  item->getName().'<br />';         echo 'Sku: '.$  item->getSku().'<br />';         echo 'Quantity: '.$  item->getQty().'<br />';         echo 'Price: '.$  item->getPrice().'<br />';         echo "<br />";                 } ?> 

But I am getting nothing. What wrong I am doing?
