How can I add the Kotlin serialization plugin or dependency?

[lexum0]

I have tried to implement Kotlin code that works on an Android app directly with SKIP INSERT: but I keep getting the error:
kotlinx.serialization.SerializationException: Serializer for class 'Country' is not found.
Please ensure that class is marked as '@Serializable' and that the serialization compiler plugin is applied.

Opening the app in Android Studio ends up saying PLUGIN_IS_NOT_ENABLED

I have tried different methods to add the serialization plugin but nothing works. I'm also using the Supatodo sample app (https://github.com/skiptools/skipapp-supatodo)

What's the right way to add serialization?

Supabase uses kotlinx.serialization to decode the query data with @Serializable (https://supabase.com/docs/guides/getting-started/quickstarts/kotlin)

In order to maintain parity with the Swift Supabase API, Skip's Supabase wrapper uses a custom CodableSerializer to handle encoding and decoding. This wasn't working for decoding previously, only encoding.

I've just added some very basic support for Codable serialization in 0.0.4 (in #5). There is still a lot of work to be done to flesh it out, but it might be enough to get started with further enhancements and PRs. Take a look at SkipSupabaseTests to see what is implemented and what isn't.

I am able to decode the data manually now thanks to the new changes, by using the new data property. Thank you

The .value property doesn't seem to be working, but I can work for now with the .data property

The .value property is working too. I ran new tests today and it's working as expected

Decoding is now working when run in the framework tests, but if I add it to an app project it won't compile giving the error:
Initializer type mismatch: expected 'skip.lib.Array<hello.supa.Country>', actual 'kotlin.Unit'. Type mismatch: inferred type is 'kotlin.Unit', but 'skip.lib.Array<hello.supa.Country>' was expected.

This error is returned for the code:
let countries: [Country] = try await client .from("countries") .select() .execute() .value

I created a new, clean app to confirm and it gives the same error. Changing the expected type to PostgresResponse<[Country]> gives the same error, it expects a kotlin.Unit type for some reason

Are you sure you are using the latest version of skip-supabase? If you run File/Packages/Update to Latest Package Versions, is there any difference?

Any what if you do more-or-less exactly what the test case does, does it still fail for you:

        let icountryResponse: PostgrestResponse<[Country]> = try await client
            .from("countries")
            .insert(Country(id: 1, name: "USA"), returning: PostgrestReturningOptions.representation)
            .execute(options: FetchOptions(head: false, count: CountOption.exact))

        try await assertCount("countries", count: 1)

        let icountry: [Country] = icountryResponse.value
