In this code i need to write

return true

My function:

override fun onBackPressed(): Boolean {
        if (amountCalculator?.visible ?: false)
            amountCalculator?.let { it.toggle(presenter.goal.amount) }
        else if (initialBalanceCalculator?.visible ?: false)
            initialBalanceCalculator?.let { it.toggle(presenter.goal.initialBalance) }
        else return false
        return true
    }

morozov: why all the nullable types? are those views? they can be lateinit var, or delegate lazy bind references

@scott https://android.jlelse.eu/dont-put-view-null-checks-in-your-presenters-4b6026c67423

right. so is that a presenter class? if so you shouldn't be referencing the views directly, but calling through an interface for normal MVP.

nope this method i used in my fragment.

so if you are handling back in your fragment, that's cool. but then why are the views nullable?
