Not 100% sure this is related to Essenty, but I think it is:

I'm getting a Kotlin compiler crash after upgrading to Decompose 2.1.0 & Kotlin 1.9.0
And adding the parcelize-darwin plugin:

error: Compilation failed: Back-end: Please report this problem <https://kotl.in/issue>

This looks like the file in question:

oh interesting, it was because there was a member of that data class that was not parcelizable. Interesting though, I added an @TypeParcelizer for that type, and it didn't fix it

[Arkadii Ivanov]

Can you provide a full stack trace? The error says toast property is of type StringResource, but in the code it's String. Also please try updating Essenty to at least 1.2.0-alpha-05 and parcelize-darwin plugin to at least 0.1.5.

[Adam Brown]

it wasn't a string, it was a moko StringResource previously, I just changed it to resolve the compiler crash: https://github.com/Wavesonics/hammer-editor/commit/31385a34d04dd114a308d4e90572287bd6ab91b8#diff-632a3c5513eb91b6728a5[…]5fe92684bfccd218fbb6ee44L41

[Adam Brown]

these are my current library versions:

[Adam Brown]

decompose = "2.1.0-alpha-07"
essenty = "1.2.0-alpha-06"
parcelize_darwin = "0.2.0"

[Arkadii Ivanov]

Ok so it was StringResource with TypeParceler annotation. Please see https://github.com/arkivanov/Essenty#custom-parcelers

[Arkadii Ivanov]

Hmm, I can see that you also have a Parceler for Instant type and I assume that works fine. So that might be something specific to the StringResource type. Wondering, how is it defined?

[Arkadii Ivanov]

Seems like this one: https://github.com/icerockdev/moko-resources/blob/master/resources/src/appleMain/kotlin/dev/icerock/moko/resources/StringResource.kt

Would be nice to see the full log.

[Adam Brown]

yep that's the one. yeah I'll get a full log after work tonight

[Arkadii Ivanov]

Thanks! For some reason, the plugin doesn't detect the TypeParceler annotation. Would be helpful to have a reproducer.

[Arkadii Ivanov]

Could you please try changing the type from StringResource? to StringResource and see if it works this way?

[Arkadii Ivanov]

If it is, I will fix the issue.

[Adam Brown]

yup, that fixes it!

[Arkadii Ivanov]

Thanks! This is a bug in the plugin.

[Arkadii Ivanov]

Fixed. See https://github.com/arkivanov/parcelize-darwin/releases/tag/0.2.1
