Basic Kotlin question. Am I right that this:

var matches = liveMatches.value
if(matches == null) {
    matches = ArrayList()
}

Can be shortened to this:

var matches = liveMatches.value ?: ArrayList()

there is also handy extension List?.orEmpty(), but you cannot use it in your case, it returns immutable empty list

Thanks for the tip, though!
