Build iOS app from Flutter source code

I have a Flutter source code and built Android app successfully, but no iOS app because of no Mac.

I want you to build a iOS app => upload it to TestFlight => give me the modified source code so I can reuse it each update.

Source code bought at Codecanyon with well documentation and I have done all configurations and integration now.

Source code is good, no errors so please do this deal in 1 day with cheapest bid.

Thank you very much!
