Arunkumar helped me get that working, but I can't seem to access the kotlin extension, and instead I have. to define it. It's ugly, but works. Anyone know of a solution?

plugins.withType(KotlinMultiplatformPlugin::class) {
        afterEvaluate {
            val kotlin = (this as ExtensionAware).extensions.getByName("kotlin") as org.jetbrains.kotlin.gradle.dsl.KotlinJvmProjectExtension
            kotlin.sourceSets.map {
                it.apply {
                    languageSettings.apply {
                        useExperimentalAnnotation("kotlin.ExperimentalStdlibApi")
                        useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
                        useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
                    }
                }
            }
        }
    }

Do not use the kotlin.sourceSets.map, since this will iterate over the current content of the source sets. Instead, you can probably drop the afterEvaluate in favour of kotlin.sourceSets.all or kotlin.sourceSets.configureEach

[Sebastian Sellmair [JB]]

Both functions all and configureEach will apply your configuration block also to all the subsequently added sourceSets. The difference between those function is:
• all will configure the source sets immediately (not lazy)
• configureEach will configure the source sets when they are required (lazy)

[Sebastian Sellmair [JB]]

You might also want to replace plugins.withType(..) { } with plugins.withType(...).configureEach { } to be "even more lazy"

Thank you for all the advice. I've followed all of it.
