Food ordering APP help needed

We’re building a mobile APP (hybrid on flutter) that has a function for food ordering from restaurants (menu, shopping cart, acceptance confirmation, ETA, etc).  Rather than invent the wheel again, was wondering where we might buy a plug in solution that would have these functions pre-built?  Modularization if possible.  I cannot imagine that with so many APPs out there, we would have to start coding from scratch?  Thank you, if you have any ideas or support.

Hi and welcome,

Using popular frameworks like Flutter you should be able to get this off the ground pretty quickly. Also try looking for other frameworks / pre-built stuff that works with Flutter.
