You may need to decipher that every time you come back to it. The indices/ mapIndexed-solution rather hide what's going on.

It's way easier to read when you come back. The syntax for using the forEachIndexed () function is as. The forEachIndexed () outputs the index items and their values. It is an inline function that accepts an array as an input. We can use the forEachIndexed () function to retrieve the current index. And I can only recommend you to use the flatMap instead. Get the Current Index of an Item in a forEach Loop Using forEachIndexed () in Kotlin. Depending on how complex your condition is, the indices themselvses will not suffice you. Note that if what you are trying to insert is static, solution with the indices is of course easier then the mapping I've presented above. It should be easy enough though to add that case. There are two main types of loops: the 'for loop' (also k. indexOf returns -1 or itemsToInsertAfterMatch = null). In Kotlin, loops are used to repeatedly execute a block of code until a specified condition is met.

what is matched with what? and what is inserted when where?).Īll the above solutions did not yet deal with the case when an element wasn't found (e.g. fun Modifier.repeatingClickable ( interactionSource: InteractionSource, enabled: Boolean true, maxDelayMillis: Long 500, minDelayMillis: Long 50. Im trying to migrate my code but I have an neverending loop because down.pressed is always true. If you do not must (and who forces you?), I wouldn't use such a construct. It tells me to use awaitEachGesture instead. As you said you iterate over the list, maybe a flatMap is rather something for you (in this example I add 'odd', 'even' after elements that are odd/even): val list = listOf('1', '2', '3', '4')Ġ -> listOf(it, ' listOf(it, ' itemsToInsertAfterMatch?.let
