ImplicitlyActualizedByJvmDeclaration

@Target(allowedTargets = [AnnotationTarget.CLASS])
@ExperimentalMultiplatform
expect annotation class ImplicitlyActualizedByJvmDeclaration(source)

This annotation marks Kotlin expect declarations that are implicitly actualized by Java.

Safety Risks

Implicit actualization bypasses safety features, potentially leading to errors or unexpected behavior. If you use this annotation, some of the expect-actual invariants are not checked.

Use this annotation only as a last resort. The annotation might stop working in future Kotlin versions without prior notice.

If you use this annotation, consider describing your use cases in KT-58545 comments.

Migration

Rewrite the code using explicit actual typealias. Unfortunately, it requires you to move your expect declarations into another package. Refer to KT-58545 for more detailed migration example.

Deprecated

Error since 2.1

Please migrate to kotlin.jvm.KotlinActual in kotlin-annotations-jvm. ImplicitlyActualizedByJvmDeclaration will be dropped in future versions of Kotlin. See https://youtrack.jetbrains.com/issue/KT-67202
