The above error has nothing to do with this.

There is big flaw in here.
In the code, mostly @TheAlphamerc has used UserModel for almost everything which always return null. When you run it debug mode, you will find that the usermodel always throws null check operator. The thing is he doesn't need to use that. The firebase provides all the functionality by using the method user.

As for the error that is displayed in the above image, it occurs due to incompatible versions of Kotlin during compilation. If you are still facing this issue you can change the kotlin version in the way mentioned below
go to android -> settings.gradle
In the plugins section of the file
plugins {
id "dev.flutter.flutter-plugin-loader" version "1.0.0"
id "com.android.application" version "7.3.0" apply false
id "org.jetbrains.kotlin.android" version "kotlin version here" apply false
}
Enter the desired kotlin version
Note: This method is for newer version of flutter as old methods included modifying the kotlin version in your build.gradle file.
