Hi. Trying to migrate from back-pressed to back-handler api to enable predictive back for jetbrains-compose with the new StackNavigation. Previously (as of 0.6.0) we had to do

val LocalBackPressedHandler: ProvidableCompositionLocal<BackPressedHandler?> = staticCompositionLocalOf { null }

// On activity
val backPressedHandler = BackPressedHandler(onBackPressedDispatcher)

setContent {
  CompositionLocalProvider(LocalBackPressedHandler provides backPressedHandler) {
    ..
  }
}

is this no longer necessary given the ChildStack has a handleBackButton?

In the previous version of that article, ComoinentContext was created manually with all arguments supplied into it, including the back handler. In the new version, the whole ComponentContext is created in the activity using defaultComponentContext extension function and is propagated via Locals.

Yes, you can just pass handleBackButton = true argument and Child Stack will automatically pop screens on back presses.

Nice 👍 working as expected
