This block was copy-pasted from my project, so as long as you have the extension function (and you have viewBinding enabled in Gradle), it should work.

inline fun <T : ViewBinding> AppCompatActivity.viewBinding(

crossinline bindingInflater: (LayoutInflater) -> T) =

lazy(LazyThreadSafetyMode.NONE) {

bindingInflater.invoke(layoutInflater)

}
