I use the flutter application programming language

I created a page containing Google Maps through which the user specifies his location to save the address and location data in his account when creating the account

When running the version on Android, it works well

But when running the version on iPhone, the map does not appear

I put all the required permissions

And I modified the AppDelegate.swift file and added the api key to the file

However, it did not work

Xcode version 16

IOS 18

dart 3.5.4

flutter 3.22
