Nested Presenters

[hscissors]

Could you point me to, or share, an example of nested presenters? By that I mean, a "child" presenter nested within another "parent" presenter, in which the parent state is partially derived from the child state.

A nested presenter would just be a presenter that is presented directly by another presenter

class MyPresenter : Presenter<State> {
  private val nestedPresenter = NestedPresenter()

  @Composable
  override fun present(): State {
    val nestedState = nestedPresenter.present()
    // Do whatever you need with nestedState, such as tunneling it in your parent State or reading information out of it
    return State(...)
  }
}

Appreciate you getting back to me. Could show how a nested presenter might invoke methods on the parent state or vis versa?

[ZacSweers]

States shouldn't have functions normally, but if you did I don't see why you couldn't just invoke them like any other function?

Ah I misread, nested presenters shouldn't have direct access to the parent presenter. That sort of breaks the contract, as the parent should just be reading or tunneling nested presenter state.
