Create flutter iOS build and upload to app store

I have three very simple and basic flutter applications with only 3-4 screens, they work perfectly on Android device.

These applications implement some popular libraries and tools such as

Firebase Realtime database, push notifications (FCM), webviews, QR code scanner, Font Awesome icons etc..

Your job is to configure this app in xcode for iOS device,
– Add splash screen
– Test on iPhone/simulator and create iOS build of these 3 applications,

I don’t have mac machine but I do have developer account. So, I want you to help me publish these applications on app store too.
