kotlinlang

Hello! Anyone faced issue like this? I’m just starting to use decompose so it might be that I’m doing something wrong.
I get this error when I try to build Android app, but iOS app builds and runs with same code in shared module.
```e: /***/shared/src/commonMain/kotlin/*/*/*/root/RootComponent.kt: (38, 10): This class does not have a constructor```
Line that reports is where I use `@Parcelize` annotation.
I use latest version of decompose: 1.0.0-alpha-07-native-compose.
I will share code in :thread: :arrow_down:

```package somepackage.root

import com.arkivanov.decompose.ComponentContext
import com.arkivanov.decompose.router.stack.ChildStack
import com.arkivanov.decompose.router.stack.StackNavigation
import com.arkivanov.decompose.router.stack.childStack
import com.arkivanov.decompose.value.Value
import com.arkivanov.essenty.parcelable.Parcelable
import com.arkivanov.essenty.parcelable.Parcelize
import somepackage.LoginComponent
import somepackage.LoginComponentImpl

interface RootComponent {
    val routerState: Value&lt;ChildStack&lt;*, Child&gt;&gt;

    sealed class Child {
        data class Login(val component: LoginComponent) : Child()
    }
}

class RootComponentImpl(context: ComponentContext) : ComponentContext by context, RootComponent {
    private val navigation = StackNavigation&lt;Config&gt;()

    override val routerState: Value&lt;ChildStack&lt;*, RootComponent.Child&gt;&gt;
        get() = childStack(
            source = navigation,
            initialConfiguration = Config.Login,
            handleBackButton = true,
            childFactory = ::createChild
        )

    private fun createChild(config: Config, context: ComponentContext) = when (config) {
        is Config.Login -&gt; RootComponent.Child.Login(LoginComponentImpl(context))
    }

    sealed class Config : Parcelable {

        @Parcelize
        object Login : Config()
    }
}```

Does the project compile from the command line?

Nope it also throws same error. Tried with `./gradlew assembleStagingDebug`
 But I also noticed now that it also throws another error:
```***/RootComponent.kt: (39, 9): Object 'Login' is not abstract and does not implement abstract base class member public abstract fun describeContents(): Int defined in somepackage.root.RootComponentImpl.Config```
But this doesn’t make sense also :thinking_face:
IDE (Android Studio) doesn’t highlight any errors.

Yeah, this is weird. Never seen this error before. What kotlin version are you using? Would you be able to provide a reproducer project?

Did you apply the parcelize Gradle plugin?

BINGO! I think I didn’t :man-facepalming::skin-tone-2:
Let me double check

Yep thank you very much <@UHAJKUSTU>
It was Gradle plugin I forgot, it works now :slightly_smiling_face:

i also face this issue before and now too . and i search through slack channel to remember what was wrong . i think you should mention to add this plugin in the documentation -&gt; getting started -&gt; Installation   . as its clearly a mandatory for decompose . anyway i tried this on compose-ios now and ios part works without applying the plugin .

Thanks for the feedback! That's mentioned in the corresponding docs section (it's highlighted with a warning box) - <https://arkivanov.github.io/Decompose/navigation/overview/#configurations-are-parcelable|https://arkivanov.github.io/Decompose/navigation/overview/#configurations-are-parcelable>

The Installation section also makes sense. I will update the docs.
