I have an expect declaration `LocalDateTime`with @Serializable(Serializer::class), and the actual implementation is a typealias to java.time.LocalDateTime. Now it complains about the missing companion object on the actual implementation. And when I move the `@Serializable`to the typealias, it complains that no serializer found for LocalDateTime. How to solve this?

Do you have a concrete code snippet? I'm not sure I understood the issue correctly...

[Loney Chou]

Sure.

// common

@Serializable(Serializer::class)
expect class LocalDateTime

object Serializer : KSerializer<LocalDateTime>

// jvm

actual typealias LocalDateTime = java.time.LocalDateTime // ERROR

Found a solution. Just create another typealias with the serializer for LocalDateTime, and leave the raw `LocalDateTime`as is.
