Fragment View Binding Delegate

FragmentAutoClearedValueBinding.kt

class FragmentAutoClearedValueBinding<T : ViewBinding>(
    val binder: (View) -> T
) : ReadOnlyProperty<Fragment, T>,
    DefaultLifecycleObserver {

    private var value: T? = null

    override fun onDestroy(owner: LifecycleOwner) {
        value = null // Clear reference.
    }

    override fun getValue(thisRef: Fragment, property: KProperty<*>): T {
        return value ?: binder(thisRef.requireView()).also {
            setValue(thisRef, it)
        }
    }

    private fun setValue(fragment: Fragment, value: T) {
        fragment.viewLifecycle.removeObserver(this)
        this.value = value
        fragment.viewLifecycle.addObserver(this)
    }
}

ViewBindingExt.kt

fun <T : ViewBinding> Fragment.viewBindingWithBinder(
    binder: (View) -> T
) = FragmentAutoClearedValueBinding(binder)

@dav-true indeed, that solves the problem!
