I can call internal symbols from other modules using `@Suppress("INVISIBLE_MEMBER")`or "INVISIBLE_REFERENCE". However that does not work for internal setter on a property. How can I suppress Cannot assign to ...: the setter is internal in ...?

[mcpiroman]

Solved by going though java wrapper, as java ignores internal. I'd still like to go through with just kotlin though.

what are the internal symbols you want to use and can you set -Xfriend-paths or associated compilations to allow access instead?

[mcpiroman]

In compose app I set `ScrollState.maxValue`(in my custom scrolling layout implementation). This is in library so I can't use friend-paths.

[ephemient]

across modules it would make more sense to use @RequiresOptIn than try to abuse internal

[mcpiroman]

Maybe but I did not make that API

This:

@Suppress("INVISIBLE_REFERENCE", "INVISIBLE_MEMBER")
fun main() {
    kotlinx.coroutines.timeSource = null
}

worked for me to access an internal var in kotlinx coroutines. Are you specifically accessing something with an internal set?

[mcpiroman]

Yup, it is public var internal set

[Youssef Shoaib [MOD]]

Found it! You need @Suppress("INVISIBLE_SETTER") . I found out from the DefaultErrorMessages.java, which lists nearly all the warnings and errors that the compiler can produce, therefore you can search for any error in that file and find its tag.

Wow, thanks! I was looking for that in source too but quite a different file.

Actually you can add -Xrender-internal-diagnostic-names compiler flag to render diagnostic names in build or enable internal mode in IDEA, so it will render this name in pop-up with diagnostic message

But don't forget that suppressing errors may be quite unstable
