Kotlin Lazy Init

May 15, 2019
Initialize and assign variable only when referred/used
class App {    val analytics by lazy {        // assume some heavy initialization        FirebaseAnalytics.getInstance(App.application)    }    fun testAnalytics() {        // analytics is only initialized once and store in variable for subsequent call        analytics.logEvent("Hello", null)        analytics.logEvent("Hello again", null)    }}

NOTE: Reference Lazy - By default, the evaluation of lazy properties is synchronized.
