flutter shopping app

I want an e-commerce normal app like amazon, Flipkart but not all features like amazon just a normal eCommerce app with flutter and firebase backed. sign-in page, login page, product page, view product/ detailed product page, and add to cart and buy with Razorpay and stripe and order history that much. there is no need to design the front end so much just normal how much is needed for the app to run. no design is needed just only the app to function.
