Flutter Bus Booking App Setup

I already own the complete Flutter bus-ticket booking source code from CodeCanyon and now need it taken all the way to a production-ready release. The repository compiles, but it still shows the stock interface; I plan a major visual overhaul, so I expect you to refactor screens, update layouts, colours, icons and any supporting assets until the new look matches the brand guidelines I will supply.

Your work starts with a clean installation, proper package upgrades and environment configuration, then moves to the UI revamp. Because I may request extra functions once we see the revamped build, the code should be organised so additional modules can drop in without big rewrites. Clean, well-commented Dart, adherence to Flutter best practices, responsive design for both Android and iOS, and Git version control are all mandatory.

Deliverables
• Fully functional Android & iOS builds ready for store submission
• Updated source code pushed to my private Git repo
• Documentation covering setup, theme structure and how to extend features

The job is finished when I can install the app from a TestFlight / internal track link, see the new interface across every screen, and run basic ticket searches, bookings and payments without errors.
