Add a ViewModel to Dessert Clicker: Android Basics in Compose

[stevoie]

Starter kit for this practice lesson references build.gradle.kts which needs modifications to the sample code snippets to work:

build.gradle.kts (project)

buildscript {
    extra.apply{
        set("lifecycle_version", "2.5.1")
    }
}

build.gradle.kts (app)

val lifecycleVersion = rootProject.extra.get("lifecycle_version") as String
...
implementation("androidx.lifecycle:lifecycle-viewmodel-compose:$lifecycleVersion")
