Hello, I have some question about stability/immutability for classes.
Here is some example:

data class MyString(
	private val stringResId: Int,
	private val args: List<MyString>,
) {
	
	@Composable
	fun getText(): String {
		val mappedArgs: Array<String> = args.map { it.getString() }.toTypedArray()
        return stringResource(textResId, *mappedArgs)
	}
}

As I understand, I can mark getText function as @ReadOnlyComposable, but what about the whole class ? Can I mark it as Immutable or Stable, or none of these annotations can be applied to this class?

And one more example:

data class MyColor(
    private val colorGetter: (@Composable () -> Color)
) {

    @Composable
    fun getColor(): Color {
        return colorGetter()
    }
}

Usage

val color = MyColor {
    MaterialTheme.colorScheme.primary
}

You can mark your class stable if you guarantee the List implementation will be stable (eg SnapshotStateList), and immutable if you guarantee the List impl will be immutable

thanks for the answer. I also thought about this, but my concerns were getColor() can return different values in case if MaterialTheme is changed from light to dark, for instance

That’s fine, the function itself isn’t changing
