A modern programming language that makes developers happier.

kotlinlang

Hi folks, I’m trying to find my way around R8 / ProGuard config. I’m just using a dummy test project with `minifyEnabled true` on the release build.

My question is, is it necessary to configure ProGuard for Kotlin serialization, if you always provide a serializer explicitly? So I mean, in every case I call it like this:
```serializer.decodeFromString(MyData.serializer(), json)
// or
serializer.encodeToString(MyData.serializer(), myObj)```
On observation, my program seems to work fine with obfuscation enabled, without any ProGuard configuration, if I am passing the serializer like this. This seems to contradict the docs:
&gt; The library works on Android, but, if you’re using ProGuard, you need to add rules to your `<http://proguard-rules.pro|proguard-rules.pro>` configuration to cover all classes that are serialized at runtime.

there's other reified functions that rely on reflection, such as
```SerializersModule {
    contextual(serializer())
    polymorphic(Base::class) {
        subclass(Sub::class)
    }
}```
but as long as you're not using those, you're safe even under r8

Thanks for responding! That’s great news
