Flutter IOS/Android Delivery App that needs deployment

I have an app in flutter that needs to be deployed I have all sources files and documentation Create Firebase and link App to connect to the Firebase. (I have documentation of what to put in firebase its basically 2-3 tables that’s all) It’s a flutter app so its Android and IOS. I would like to “deploy” them which means to have .apk and .ipa , All source code is available. Need to change main page logo since company name changed ! Which once again is very easy since I have source code. I have documentation on almost everything even on how to deploy. So I will be sending it also. The app is a delivery app between Restaurant Owners and Delivery drivers. It lets restaurant ask for a delivery to X address and driver receives notification , accepts, and gets directions on where to go to pickup(the restaurant) and where to deliver. App has admin backend which is in .php The app is 98-99% there are some little bugs that need fixing but I don’t remember exactly if they were fixed but they are minor bugs; Example; there is an option to choose from which restaurants each driver can receive order. There was a bug where it doesn’t chose the ones I want but I don’t remember if this was fixed. After deployment I will do a stress test and tell you we can even do it together
