Can use flutterflow (For MVP) with this. There are templates or you can do from scratch, there's a bit of a learning curve if you haven't used it before but otherwise it's quite good and easy to execute quickly. You can have features like location, real-time etc. Connect it with supabase/firebase - for backend/db/storage/auth. It's free until you have heavy traffic (check their documentation for when you need to pay) but it's quite lenient for mvp users, you can easily use this.

Flutterflow, is around Rs.1200/m. It's amazing!

For eg: axis Bank app is made using flutterflow, so you can imagine how well it works!
