eCommerce Flutter App and Mobile App setup

We have purchased the eCommerce and mobile App from the below source:
PHP, Laravel 8 is used as the language
NextJS framework

https://codecanyon.net/item/shopo-multivendor-ecommerce-flutter-app/39965496


We need to change the logo Icon on the mobile app and the website
I need to build a feature in the product details page like this on this page https://www.99rpm.com/bajaj/abs-sensor-ns160-twin-disc-2018-20.html
this feature will be available on both mobile apps and web apps
This feature will have to have Turn on /Off in settings. Only when turned on must it show in the web app and mobile apps.
Setup the website on the Vercel Server FREE Hosting
Publish the apps on respective app stores.
Android App on Google Play store
iOS Apps on App Store

Server Setup
