why is this

fun intervalFlow(delayMillis: Long): Flow<Int> {
    return flow {
        withContext(Dispatchers.Default) {
            var i = 0
            emit(i)
            while (true) {
                delay(delayMillis)
                emit(++i)
            }
        }
    }
}

wrong -- I mean I read the article, but at runtime it doesnt crash, and printing threads in each step, seems correct

It's explained in the docs.

Solution is to use flowOn or replace flow with channelFlow.
