It seems like you cannot use kotlinx.coroutines.flow.MutableStateFlow in common code? Only platform-specific code?

I didn’t check myself, but it should be available there, it’s in common code: https://github.com/Kotlin/kotlinx.coroutines/blob/master/kotlinx-coroutines-core/common/src/flow/StateFlow.kt#L123

Yeah the rest of the "flow" namespace seems to be available but not the new-ish StateFlow's which i thought was weird. Im unable to import it and get an error while building about it being an unresolved reference

are you sure that you use 1.3.6+ for common code? Maybe just common uses an old version

I think i am:

sourceSets {
	def coroutines_version = "1.3.7"
	commonMain {
            dependencies {
                implementation(kotlin('stdlib-common'))
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutines_version")
                // ...
            }
        }

Interesting, I thought that it already works with Gradle metadata without separate dependencies Do you use the latest Gradle?

Could be because of that, im not on the latest Gradle (using 3.6.3 , 4.x should be out now)

3.6.3? Don't think it's Gradle version, looks like Android Gradle Plugin version

i’m definitely using

MutableStateFlow

in my common code fwiw

Ahh, transitive dependency can break it, just because there are 2 artifacts with different name but same content, had similar issue when kotlin stdlib artifact was renamed from jre to jdk I think the better solution is exclude it on level of Gradle

@Mgj Reading your

build.gradle

snippet, I'm not seeing the dependency on kotlinx coroutines common for commonMain, you specified the JVM artifact (note: this becomes correct starting Kotlin 1.4-M2 because these artifacts start being Multiplatform publications)

Oh, so Gradle metadata for coroutines works only from 1.4

Before 1.4, it works with

-native

prefixed artifacts.

Yes, right, it was only for different native platforms. It was quite messy experience to have all those different dependencies for every platform Even for stdlib or ootlin-test

Actually, it works for non Kotlin/Native targets/platforms as well, but these are gone(replaced) for 1.4-M2

Interesting.... good to know, thank you
