Hi, we can develop your app with Flutter, same lines code in IOS and Android, i have experience with Ecommerce Apps, i used to implement Google Maps SDK, Users Profiles, Address Searchers and more.. this is a challenge for me, I wrote 40 days, because, I'm sincerly, I prefer to talk with you how exactly you want it, about Design and Functions App, my clients design me the Apps, they wrote me in Google Word each functions, step by step, if something must be changed, we do it without any problem, in each app I do, you have 2 month of maintenance code freely.
I think this app must be developed with Flutter, Firebase and Google Maps SDK.
If you wanna more information about my last App, contact me.
Kind regards
Oberti Rodrigo
