@RawValue annotation is not applicable to target value parameter

Question

I am trying to Parcelize a data class. It contains one parameter :

var tokenType: Any? = null

For this variable compiler complains at compile time that :

Type is not directly supported by Parcelize. 
Annotate the parameter with @RawValue if you want it to be serialized via 
writeValue()

Though the error is self-explanatory, when I add @RawValue like this:

@RawValue var tokenType: Any? = null

it gives an error :

This annotation is not applicable to the target value parameter

Any hints on how to handle this?

I got the answer to this problem from Kotlang community. Answer is you can not annotate the variable itself but you have to annotate its type.

So annotating in the following way removes the error :

 var tokenType: @RawValue Any? = null

Though do not forget to write serilizer/deserializer for this property manually as it will not be done automatically.

After seeing this answer I immediately realised understood what target annotation meant, thank you! – wax911 Dec 17 '18 at 09:16

How do you write the serilizer/deserializer for the Any type? – Beast77 Oct 13 '19 at 06:46
@Beast77 Please use normal writeToParcel and readFromParcel Methods for same as is used without Parcelize keyword. – Tarun Deep Attri Oct 14 '19 at 09:17

@Tarun why would you use Parcelize for then? – frapeti Oct 27 '19 at 03:40

You can add a link to the thread on `KotLang` to help others get more context. – KE Keronei Aug 11 '22 at 09:24

Remember to add annotation @Serializable to object/class – MisterAnt Feb 23 '23 at 09:14
