Update Flutter App and Submit to Apple store

I'm looking for a Flutter developer to update my e-commerce app. In my app, only logged-in users can access the home screen and products. So, I want to implement a "skip login" button for non-logged-in users to access the home screen and products. However, these users should not be able to purchase items without logging in.

Other requirements:-

- Update the apps to target the latest API level.
-Provide source code and aab file for Play Store upload.
-Upload the IPO file to my Apple developer account with the necessary screenshots.
