Magento – Quote item price changes

magento2quoteitem

Can someone suggest if there is any function to update the quote item tables price columns

(custom_price,original_custom_price,row_total,qty,price,base_price,row_total,base_row_total,price_incl_tax,base_price_incl_tax,row_total_incl_tax,base_row_total_incl_tax
etc)

changes internally rather than calculating and updating each column manually?

When a product price change happens, the quote details are not changing. I was trying to add code for the same while checking out, where mini cart details were not getting updated.

You can update cart item price using customer login observer. While customer login the cart item will updated with new price.

app/code/Vendor/Customer/etc/frontend/events.xml

    </event>
</config>
