[Bug]: install(GoTrue) throws error in native kotlin

[ferhatwi]

General Info

• I installed the latest version of Supabase-Kt
• I checked for similar bug report

What happened? (include your code)

suspend fun main() {


    val client = createSupabaseClient(
        supabaseUrl = url,
        supabaseKey = key
    ) {
        install(GoTrue)
        install(Postgrest)
    }
}

This code is in the Playground.kt file.
install(Postgrest) works fine in both native and Android environment.
install(GoTrue) works fine in Android environment but throws error in native.

Platform(s)

Native

Which native platform?

[ferhatwi]

If code is independent of Android context (e.g.: Playground.kt file and a main function in it) install(GoTrue) method throws error. I basically run the PlaygroundKt file, not the app configuration.

Okay the problem is that GoTrue couldn't create a default Settings instance (for saving & loading sessions), which causes this error (will improve this error in the next version). What you can do is provide a Map-based Settings instance using the multiplatform-settings-test library, which works independently of the context/platform or pick a different one from the repo
Example with MapSettings:

implementation("com.russhwolf:multiplatform-settings-test:1.0.0")

Then in the supabase client builder:

install(GoTrue) {
    sessionManager = SettingsSessionManager(MapSettings())
} 

This is also available in the wiki

Okay, thanks!
