Magento – Magento2: Show price on bundle option summary

Magento has default feature of Bundle product price to show on the listing and product view page. It should be shown the min price on the listing page like, Starting at $5 or as low as $5, and on the product page, the user can see the full price as there is the bundle.

So finally I was able to achieve this, first we need a events.xml

For my requirement I needed this event observer for both frontend and adminhtml so the events.xml was create at app/code/Foo/CustomPrice/etc/events.xml.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <!-- Event for add to cart -->
    <event name="checkout_cart_product_add_after">
        <observer name="foo_customprice_observer_set_price_for_item_add" instance="Foo\CustomPrice\Model\Observer\SetPriceForItem"/>
    </event>
    <!-- Event for update add to cart -->
    <event name="checkout_cart_product_update_after">
        <observer name="foo_customprice_observer_set_price_for_item_update" instance="Foo\CustomPrice\Model\Observer\SetPriceForItem"/>
    </event>
</config>

After that need a observer at app/code/Foo/CustomPrice/Model/Observer/SetPriceForItem.php

<?php
namespace Foo\CustomPrice\Model\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Catalog\Model\Product\Type;

class SetPriceForItem implements ObserverInterface
{
    /**
     * Add Special Price on add to cart.
     *
     * @param Observer $observer
     * @return SetPriceForItem
     *
     */
     public function execute(Observer $observer)
     {
        /** @var $item \Magento\Quote\Model\Quote\Item */
        $item = $observer->getEvent()->getQuoteItem();
        if ($item->getProduct()->getTypeId() == Type::TYPE_BUNDLE) {
            foreach ($item->getQuote()->getAllItems() as $bundleitems) {
                /** @var $bundleitems\Magento\Quote\Model\Quote\Item */
                //Skip the bundle product
                if ($bundleitems->getProduct()->getTypeId() == Type::TYPE_BUNDLE) {
                    continue;
                }
                $bundleitems->setCustomPrice(1.00);
                $bundleitems->setOriginalCustomPrice(1.00); 
                $bundleitems->getProduct()->setIsSuperMode(true);   

            }
            $item->getProduct()->setIsSuperMode(true);
        }
        return $this;
     }//end execute()
}
