I created a SharedFlow, and first I added a Collector to it. Then six coroutines were started to emit data inside. Delay for a certain amount of time to ensure that the data has been emitted. cancel some coroutines. Then added a new collector.
fun main() = runBlocking {
//create a sharedFlow
val flow = MutableSharedFlow<Int>()
//add collector 1
launch(Dispatchers.IO) {
flow.collect {
log("collector_1 received $it")
delay(3000)
}
}
delay(1000)
val job1 = launch {
flow.emit(1)
}
val job2 = launch {
flow.emit(2)
}
val job3 = launch {
flow.emit(3)
}
val job4 = launch {
flow.emit(4)
}
val job5 = launch {
flow.emit(5)
}
val job6 = launch {
flow.emit(6)
}
delay(1000)
//cancel some job
job2.cancel()
job3.cancel()
job4.cancel()
delay(1000)
launch(Dispatchers.IO) {
flow.collect {
log("collector_2 received $it")
}
}
log("")
}
the code above only print "collector_1 received 1"， then two collector suspend。 the number "5" and "6" missed . But， if we don't cancel any job, they will print correct.
