Flutter Shop Project

I am looking for a Flutter developer to debug a mobile app shop, I switched the routing from navigator to go router which is making some of the features of the app not work. It is for both Android and iOS platforms. This project is for personal use and does not require any complex features. The project is already built and ready to deploy I just need debugging help.The ideal candidate should have experience in Flutter development and be able to create a user-friendly interface for the shop application.
