Opt-in requirement marker annotation on override requires the same marker on base declaration

各記述を以下のように個別に置き換えるのがとりあえずシンプルでいいのかな。


@FlowPreview
→ @OptIn(FlowPreview::class)




@ExperimentalCoroutinesApi
→ @OptIn(ExperimentalCoroutinesApi::class)

gradle で一括で無視しときますか?

subprojects {
// ...
tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
kotlinOptions {
allWarningsAsErrors = false
freeCompilerArgs += [
"-Xopt-in=kotlin.RequiresOptIn",
"-Xopt-in=kotlinx.coroutines.ExperimentalCoroutinesApi",
"-Xopt-in=kotlinx.coroutines.FlowPreview",
"-Xopt-in=kotlinx.serialization.ExperimentalSerializationApi",
"-Xopt-in=kotlin.Experimental"
]
}
}
}

いうて、まだまだ変更がありそうなところではある。
