Android LiveData prevent receive the last value on observe

Question

Is it possible to prevent LiveData receive the last value when start observing? I am considering to use LiveData as events.

For example eve

Answer 1

According to answer of jurij-pitulja.

if we are using kotlin coroutines the solution look likes this.

class Event(private val content: T) {

    var isHandled = false
    private set

    fun getContentIfNotHandled(): T? {
        return takeIf { !isHandled }?.let {
            isHandled = true
            content
        }
    }
}

Inside of view model class replacing Flow.asLiveData() into emit new Event

val authResult: LiveData>> = _emailLiveData.switchMap { email ->
    liveData{
        repository.authRequest(email).collect{
            emit(Event(it))
        }
    }
}

Implementing observer method inside of fragment

viewModel.authResult.observe(viewLifecycleOwner){
            it.getContentIfNotHandled()?.run {
                onAuthRequestComplete(this)
            }
        }
