Prerequisites in Kotlin - Good Practices

Question

As a newcomer to the Kotlin coder, I wonder if there are any good practices or even language constructs for declaring preconditions in functions.

In Java, I used the Guava Preconditions validation utilities:

After some further research, I came across the require function:

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/require.html

Is this what is commonly used to test prerequisites for functions?
