Hello ! I would like to do something on a list, i think there is a function i don't know but i don't find it... Here is my code :

val stringList = somethingList.map {
   it.str
}

if (stringList.isNotEmpty()) {
   doSomethingWithMyList(stringList)
}

And i would like to do something like that

somethingList.map {
   it.str
}.unknownOperation { // here i need help
   doSomethingWithMyList(it)
}

also

?

I have already seen i can use something like :

.also {
 if (isNotEmpty()) {
   doSomethingWithMyList(it)
  }
}

but i just would like to know if there is an operator or another way to do the apply and if not empty

you can also use

.takeIf { it.isNotEmpty() }?.let{ doSomething(it)}

Thanks, didn't know takeIf 👍
