Some apps haven't been configured to use Apple's SKAdNetwork

After I publish my Flutter app on Apple App Store Admob gave this warning.

Some apps haven't been configured to use Apple's SKAdNetwork

To ensure you're getting credit for all ads activity, like app installs, be sure to configure SKAdNetwork with Google's network IDs.

When I click "Get instructions" button. It opens this page: https://developers.google.com/admob/ios/ios14?hl=en-GB

But as you know, this page is not for Flutter. This page is for Native iOS apps developing by Swift or Objective-C.

How can I configure Apple's SKAdNetwork in Flutter? Where to edit - change?

Interestingly, there is no source for this problem in the Internet.

I feel like the first person in the world to develop Flutter.

Really, there is no solution - no source in Flutter for this problem!

Note: There is no information about this problem in this source too: https://developers.google.com/admob/flutter/quick-start#ios

EDIT: Must I implement ATT to configure SKAdNetwork? What happens if I only change Info.plist?

Even with flutter applications, you have different configuration files for iOS and Android. Look for the Info.plist file within your project (you must have one, usually under ios/Runner and update the keys as mentioned in the link you have attached

I solved my problem, this warning has been removed automatically. I was using out-dated admob SDK.

https://pub.dev/packages/google_mobile_ads/install

SOLUTION: Update your admob SDK to latest version.

I edited my pubspec.yaml file.

dependencies:
  google_mobile_ads: ^1.0.1

I updated my app on App Store so no warning is seen now in Admob Panel.
