I am trying to connect a IOS Firebase app to my flutter and the packages I am importing come up with the error "The library 'package:firebase_auth_web/firebase_auth_web.dart' is legacy, and should not be imported into a null safe library. Try migrating the imported library".

There is more than one problem as per your description and comments. The easiest solution is to upgrade the dart, flutter, and all the dependencies you are using because it seems that you are using all the things which are older.
First, in your command prompt (terminal), run:
> flutter upgrade
This will upgrade your flutter and dart both. Secondly, run:
> flutter pub upgrade
This will upgrade all the dependencies. Finally, run:
> flutter pub upgrade --major-version
This will also upgrade all the dependencies.
Doing these will make your application up to date with the dependencies. Now, try to run the app again. Most probably it will work, if it doesn't then it might tell you to upgrade your compileSdkVersion in build.gradle to something larger number. If so, upgrade that number in your app>build.gradle file.
