In Kotlin functions get or set can be replaced with the shorter operator [], see https://kotlinlang.org/docs/operator-overloading.html#indexed-access-operator. Prefer the usage of the indexed access operator [] for map or list element access or insert methods.

Noncompliant Code

val map = Map<String, String>()
map.put("key", "value")
val value = map.get("key")

Compliant Code

val map = Map<String, String>()
map["key"] = "value"
val value = map["key"]
