Reports var declarations (both local variables and private class properties) that could be val, as they are not re-assigned. Val declarations are assign-once (read-only), which makes understanding the current state easier.

Noncompliant Code

fun example() {
    var i = 1 // violation: this variable is never re-assigned
    val j = i + 1
}

Compliant Code

fun example() {
    val i = 1
    val j = i + 1
}
