How do we know which element is minimum in loop kotlin

Question

Hey I have list in kotlin. I am iterating over it. I want to store true/false as flag index which one is minimum value in whole list. I tried some code, but it's not working.

fun main() {
    val list = mutableListOf(4.83, 4.39, 3.58, 3.50, 3.46)
    val minValue = mutableListOf<BestMinimumValue>()
    var previousValue = 0.0

    list.forEach {
        minValue.add(BestMinimumValue(compareValue = previousValue > it))
        previousValue = it
    }
    minValue.forEach {
        println(it)
    }
}

data class BestMinimumValue(
    val compareValue: Boolean
)

Actual Output

BestMinimumValue(compareValue=false)
BestMinimumValue(compareValue=true)
BestMinimumValue(compareValue=true)
BestMinimumValue(compareValue=true)
BestMinimumValue(compareValue=true)

I'll explain what I need. In my list 3.46 is minimum value so on that place I need the flag as true and other one will be false.

Expected Output

BestMinimumValue(compareValue=false)
BestMinimumValue(compareValue=false)
BestMinimumValue(compareValue=false)
BestMinimumValue(compareValue=false)
BestMinimumValue(compareValue=true)
