Add features to existing Flutter food delivery app source code

Hello. Please check the complete details on the attached PDF file. In your bid, please inform me if you can also create a front end PHP website or you only know Flutter. Please read the requirements thoroughly: Create a front-end website (Php) and connect it to the Flutter app. I already purchased the source codes of the customer, rider, and restaurant app. The Laravel admin panel is included. These are the customizations I need for the app: Use my logo and color The delivery fee should be dynamic and based on the distance by base km plus succeeding km. Only the admin should have access. The restaurant can have its own designated delivery boy but for standard, orders should be assigned automatically except for restaurants that have their own drivers. Live tracking of orders Firebase in-app chat messages with pre-typed options for driver and customer conversation Remove the last name of the customer on order info. Only the first letter of the last name string will show. Admin can see the complete name and details of the customer Rider and restaurant will have an acceptance rate, cancellation rate, and ratings (Order acceptance speed + wait time compared to other restaurants on average + Average order Show filtered dates of total profit/commission in the dashboard and total sales, show most sold items, highest sales by restaurant total, payment method, and per city on restaurant dashboard and admin panel ranking) Add cancel order reason for restaurants Add a free delivery coupon, referral code, small order fee, schedule order, and reorder option If you understand my requirements please use "I know Flutter" on top of your proposal.
