Hi everyone, I have a question, Is possible collect/process more than one flow inside launch block?
my code is like

launch{
flow1.collect{ ... }
flow2.collect{ ... }
...
}

but only flow1 is executed, if comment flow1 then flow2 is executed

[nrobi]

Well everything after the collect will suspend, until your first flow terminates/closes this way

[nrobi]

So you need to collect them in different scopes

[kristianconk]

wow, that make sense, my flow1 is an infinite loop

[kristianconk]

while(true){
emit(data)
delay(1000)
}

There is a convenience function for this: https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/launch-in.html

Yupp. Most of the time I'm also using the
flow.onEach { .... }.launchIn(yourScope) as @Jason Ostrander suggested

[kristianconk]

thank you! I will use it

So you need to collect them in different scopes

Not different scopes, but different coroutine to collect each, scope can be the same

[nrobi]

Yes, you're right. My bad, I didn't mean the coroutineScope, rather the scope of the lambda/launch
