A Kotlin delegated property implementation which automatically clears itself at appropriate times in the View Lifecycle of a Fragment.

ViewLifecycleAware.kt

import androidx.fragment.app.Fragment
import androidx.lifecycle.DefaultLifecycleObserver
import androidx.lifecycle.LifecycleOwner
import kotlin.properties.ReadOnlyProperty
import kotlin.reflect.KProperty

fun <T> Fragment.viewLifecycleAware(initialise: () -> T): ReadOnlyProperty<Fragment, T> =
	object : ReadOnlyProperty<Fragment, T>, DefaultLifecycleObserver {

		private var binding: T? = null

		override fun onDestroy(owner: LifecycleOwner) {
			binding = null
		}

		override fun getValue(thisRef: Fragment, property: KProperty<*>): T =
			binding
				?: initialise().also {
					binding = it
					[email protected](this)
				}
	}

Important to note that LifecycleObserver is found in "androidx.lifecycle:lifecycle-common-java8:$version"
