I’m trying to add proguard for my sdk project and I have a suspend methods in my sdk package. suspend methods signature change like this when I enabled proguard.

Java decompile code

 @Nullable
 public final Object getVideosAsync(@NotNull xxx.Params var1, @NotNull Function1<? super Pair<xxx, ? extends List<Error>>, Unit> var2, @NotNull Continuation<? super Unit> var3) {
               ...

my sdk kotlin code:

suspend fun getVideosAsync(
            params: xxx.Params = xxx.Params(),
            onReceived: (Pair<xxx?, List<xxx>?>) -> Unit
        ) {
            if (XXXInjection.isInitialized().not()) return
            val response = XXXInjection.provideVideoRepository().getVideos(params)
            onReceived(response)
        }

I tried to fix by adding some rules for continuation problem like below.

1- -keep Signature

2- -keep class kotlin.Metadata

3- -keep,allowobfuscation,allowshrinking class kotlin.coroutines.Continuation

But I could not prevent the Continuation parameter from being added to the suspend methods, so when I try to call the suspend methods, it asks me for the Continuation parameter and this is ridiculous. I wonder if this decompiles into java code or is there a method to decompile it into kotlin code? So, Proguard should obfuscate Kotlin code from Kotlin, is this possible? So I thought suspend methods would work properly?
