Add a ViewModel to Dessert Clicker: Android Basics in Compose

Codelab - Practice: Add a ViewModel to Dessert Clicker

Codelab step 3 - Set up dependencies

It says to add this fragment to build.gradle:

buildscript {
   ext {
       ...
       lifecycle_version = '2.5.1'
   }
}

Which isn't working for kotlin DSL. I had to add this instead:

buildscript {
    val lifecycle_version by extra("2.5.1")
}

The second snippet doesn't work either, I used this:

implementation("androidx.lifecycle:lifecycle-viewmodel-compose:${rootProject.extra["lifecycle_version"]}")
