How To Get Customoptions From Quote and Order In Magento 2

How To Get Customoptions From Quote and Order In Magento 2 : Here i am going to let you know. how you can get custom option from quote and order.
i will describe both separately.
1 => get custom option from quote :

/**
 * @var \Magento\Checkout\Model\Cart
 */
protected $_cartModel;
 
/**
 * @param Context                             $context
 * @param \Magento\Checkout\Model\Cart        $cartModel
 */
public function __construct(
    Context $context,
    \Magento\Checkout\Model\Cart $cartModel,
) {
    $this->_cartModel = $cartModel;
    parent::__construct($context);
}

public function execute()
{
    // _cartModel is an instance of \Magento\Checkout\Model\Cart
    $quote = $this->_cartModel->getQuote();
    $cartAllItems = $quote->getAllItems();
    foreach ($cartAllItems as $item) {
        $options = $item->getProduct()->getTypeInstance(true)
        ->getOrderOptions($item->getProduct());
        foreach ($options as $option) {
            $itemOptions = $option;
            //itemOptions contain all the custom option of an item
        }
    }
}

here _cartModel is an instance of \Magento\Checkout\Model\Cart .
itemOptions contains custom options of item.

2 => get custom option from order :

<?php
/**
 * @var \Magento\Checkout\Model\Cart
 */
protected $_cartModel;
 
/**
 * @param Context                             $context
 * @param \Magento\Sales\Model\Order          $order
 */
public function __construct(
    Context $context,
    \Magento\Sales\Model\Order $order,
) {
    $this->_order = $order;
    parent::__construct($context);
}

public function execute()
{
    // _order is an instance of \Magento\Sales\Model\Order
    $order = $this->_order->load('order_id');
    $orderAllItems = $order->getAllItems();
    foreach ($orderAllItems as $item) {  
        $options = $item->getProductOptions();
        foreach ($options as $option) {
            // $option contains custom option of an item
        }
    }
}

here _order is an instance of \Magento\Sales\Model\Order
Hope so it will help you.
