recently played with it and added an example with comments here - https://github.com/vinaygaba/Learn-Jetpack-Compose-By-Example/blob/master/app/src/main/java/com/example/jetpackcompose/state/coroutine/CoroutineFlowActivity.kt

I was looking for a simple example online, but I could not find it

did you have any chance to play with StateFlow and SwiftUI in a KotlinMultiplatform context?

I wish it was so simple too, but I doubt it 😄

you gave me a very clear starting point, I am very glad

Hi Vinay, I have a question about your sample. Is “initial” a special keyword?

is it specific of Flow?

thanks!

as far as I understand StateFlow is a hot flow, while Flow is a cold flow

which is the effect of using Flow instead of StateFlow inside a Composable?

I was reading that: “StateFlow only returns if the value has updated and doesn’t return the same value. In simpler terms, consider two values x and y where x is the value initially emitted and y is the value to be emitted. StateFlow makes sure, if 

(x == y)

 the do nothing but if 

(x !=y)

 then only emit the new value i.e. y in this case.”

That’s why the

StateFlow.collectAsState()

doesn’t require you to pass in an initial value, but

Flow.collectAsState

does.

as far as I understand StateFlow is a hot flow, while Flow is a cold flow

Not exactly. A

Flow

can be hot as well, since

StateFlow

is a subtype of

Flow

. The types don’t necessarily imply anything about their “temperature”.

Unlike

Flow

vs

Channel

, where

Channel

is always hot.
