Can someone explain me why the second child is not cancelled? ``` coroutineScope { launch { if ...

# coroutines

Can someone explain me why the second child is not cancelled?

coroutineScope {
		launch {
			if (condition) cancel() // does not cancel the coroutine of flow
		}
		
		launch {
			dataSource.channel.receiveAsFlow() {
				.collect { doSomething() }
		}
	}

I would expect that cancelling first coroutine would cancel second coroutine but it doesn't. Any ideas?

It'd if it crashed (i.e. you throw a non CancellationException), but I guess what you're looking for here is doing [e-mail]().

The reason is that launch will create a new CoroutineScope for the job which is different from the outer scope. You are canceling the inner scope so it won't affect other jobs in the outer scope.

@Albert Chang hmm but coroutineScope states: "When any child coroutine in this scope fails, this scope fails and all the rest of the children are cancelled". My example macthes this statement exactly, not?

[Albert Chang]

@Lilly "fails" means throwing exception other than CancellationException.

Ah oookk, got it!

[louiscad]

Yep, fails is what I called "crashed"
