multiple presenters on a complex screen

[Jparrgam]

Currently, I'm working on a complex screen and I realized that with Circuit, it's possible to divide a screen into presenters according to the code documentation

Just adding each factory to the parent would be enough, or would I need to do something else?

I have mine set up as follows.

class HomePresenter @Inject constructor(
    private val similaritiesPresenter: SimilaritiesPresenter.Factory,
    private val feedListPresenter: FeedListPresenter.Factory
) : Presenter.Factory {
    override fun create(
        screen: Screen,
        navigator: Navigator,
        context: CircuitContext
    ): Presenter<*>? {
        return when (screen) {
            is SimilaritiesScreen ->
                similaritiesPresenter.create(navigator, screen)

            is FeedListScreen ->
                feedListPresenter.create(navigator)

            else ->
                null
        }
    }
}

But my question is how do I use the HomePresenter? I think it's the simplest step, but I can't get it to work.

Are you using Anvil? Maybe do the annotation for @CircuitInject?

@JohnBuhanan yes i use anvil, if I use @CircuitInject in the child presenters, how would I apply it to the parent?

[ZacSweers]

You would inject the generated *Presenter.Factory into your parent presenter

[Jparrgam]

@ZacSweers And how would you use the parent presenter? Sorry for the insistence, I just want to understand a little how this part works

You haven't really explained anything about what you're trying to do, I think this may be best left as an exercise to the reader.
