I am trying to use my own/REAL AdUnits instead of the TestAdUnits but I have no idea where to get the Test Device Ids for my iOS and Android devices.
Docs say to look at the logs to locate the test id, but I have inspected everything that gets printed to the console and it does not print either of the devices test ids.
I am building and running my project in VS Code
After a while of looking through logs, I realized there are some missing steps in Flutter's package explanation.
First, Firebase needs to be linked to you AdMob app, AND you need to re-download the GoogleService-Info.plist file for iOS and the google-services.json for Android.
After that, in iOS you need to go into Settings -> Privacy -> Advertising and disable Limit Ad Tracking. This will allow for the ID to be printed.
