hi guys - i have code that roughly looks like this were I poll on an endpoint until the result changes. My current code passes in the time interval as a parameter

data class ApiResponse(
    val someId: Long,
    val success: Boolean,
)

suspend fun ApiResponse.poll(interval: Long) {
    var result = success
    while (!result) {
        result = sendSomeApiRequest(someId)
        delay(interval)
    }
}

A requirement I need to support is allowing users of this function to change the

interval

value while polling occurs based on outside information. would the most idiomatic way to do this be using a

StateFlow

? so my above function would become

suspend fun ApiResponse.poll(interval: StateFlow<Long>)

Atomic long should do I think. Unless you need some reactivity.

no - only adjust the next delay

suspend fun ApiResponse.poll(onRetry: suspend (ApiResponse) -> Unit) {

personally I'd probably do this - let the caller set up the delay, or whatever else is desired (print, counter, etc.)
