Hi, I am facing this error on flutter native ads (android) PlatformException(NativeAdError, Can't find NativeAdFactory with id: homeScreen, null, null)

this is my HomeScreenNativeAd.kt file

class HomeScreenNativeAd(val context: Context) : GoogleMobileAdsPlugin.NativeAdFactory {

    override fun createNativeAd(
            nativeAd: NativeAd,
            customOptions: MutableMap<String, Any>?
    ): NativeAdView {
        val homeScreenNativeView = LayoutInflater.from(context)
                .inflate(R.layout.home_screen_native_ad, null) as NativeAdView

        with(homeScreenNativeView) {
            val attributionViewSmall =
                    findViewById<TextView>(R.id.tv_home_item_native_ad_attribution_small)


            val icon = findViewById<ImageView>(R.id.home_item_bg_image)


            val image = nativeAd.icon
            if (image != null) {
                attributionViewSmall.visibility = View.VISIBLE
                icon.setImageDrawable(image.drawable)
            } else {
                attributionViewSmall.visibility = View.INVISIBLE
            }
            this.iconView = iconView

            val adV =   findViewById<TextView>(R.id.adviser)
            adV.text = nativeAd.advertiser
            this.advertiserView =adV

            val ctaButton =   findViewById<TextView>(R.id.home_screen_cta_button)
            ctaButton.text = nativeAd.callToAction
            this.callToActionView = ctaButton

            val adDesc =   findViewById<TextView>(R.id.home_item_ad_desc)
            adDesc.text = nativeAd.body
            this.bodyView = ctaButton



            val headlineView = findViewById<TextView>(R.id.home_item_ad_title)
            headlineView.text = nativeAd.headline
            this.headlineView = headlineView




            setNativeAd(nativeAd)
        }
