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.
