ViewDelegates

• Should perform all view related tasks and be fairly dumb (no business logic)
• Should inherit from BaseViewDelegate
• Should override renderViewState(...) to process incoming ViewStates
• Can contain contexts, views or anything else that you would normally put in an Activity/Fragment
• Should contain your findViewById calls
• Should contain your various view listeners (onClick, onCheckChanged etc..)
• Should leverage pushEvent(...) to expose a meaningful ViewEvent

How do I apply important fields to all events?

You likely have a base class for your own MyAppBaseViewDelegate. In there you can override onInterceptEventChain().

// Create your base view event. All of your view events should extend from this event
open class BaseDefaultViewEvent : ViewEvent {
    lateinit var importantSharedField: String
}

// Create your own variant of a BaseMyAppViewDelegate
// Note that the event extends from `BaseDefaultViewEvent`
abstract class MyAppBaseViewDelegate(
    view: View,
    lifecycleOwner: LifecycleOwner
) : BaseViewDelegate(lifecycleOwner, view) {

    // Override this method and inject any fields you defined
    override fun onInterceptEventChain(event: ViewEvent) {
        event.importantSharedField = provideImportantField()
    }

    abstract fun provideImportantField() : String
}
