Hi there. I’m facing a proguard setting issue This is my code

private val onPriceButtonClick = { searchConditionId: Int?, isPriceNotification: Boolean ->
        viewModel.updatePriceNotification(searchConditionId, !isPriceNotification)
}

...
it.setOnPriceButtonClick {
       onPriceButtonClick.invoke(searchConditionId, isPriceNotification)
 }

This code works without setting proguard But after setting proguard, the value of

searchConditionId

is always

null

. Should I keep the searchConditionId and isPriceNotification attribute? Any help will be appreciated!
