Say I have a Flow of Booleans and only want to emit when they flip what is the proper way to do that What am I looking for ```suspend fun Flow lt Boolean gt flippedTo value Boolean block gt Unit var previous Boolean = null collect current gt if previous == value amp amp current == value block previous = current boolFlow flippedTo false println Flipped from true to false boolFlow flippedTo true println Flipped from false to true ```

Maybe try `distinctUntilChanged` Or that point up

Say I have a Flow of Booleans and only want to emit when they flip, what is the proper way to do that? What am I looking for?

suspend fun Flow<Boolean>.flippedTo(value: Boolean, block: () -> Unit) {
    var previous: Boolean? = null
    collect { current ->
        if (previous == !value && current == value) {
            block()
        }
        previous = current
    }
}
boolFlow.flippedTo(false) {
    println("Flipped from true to false")
}
boolFlow.flippedTo(true) {
    println("Flipped from false to true")
}

StateFlow is not enough?
