Field doesn't define in the RegistrationActivity class in https://developer.android.com/codelabs/android-dagger#10

The registrationComponent filed not defined as a class field. It may be confusable Could you change from

class RegistrationActivity : AppCompatActivity() {
    ...
    override fun onCreate(savedInstanceState: Bundle?) {

to

class RegistrationActivity : AppCompatActivity() {
    lateinit var registrationComponent: RegistrationComponent
    ...
    override fun onCreate(savedInstanceState: Bundle?) {
