Flutter local_auth 平台异常要求activity为fragmentactivity flutter

Question

我正在使用插件local_auth 让用户通过指纹进行身份验证，现在我知道需要在“mainActivity.kt”上进行一些更改，因此插件可以正常工作而不会出现错误local_auth plugin requires activity to be a fragmentactivity flutter

但问题是我也在使用 google_ads 插件，我正在使用它注册原生广告，使用类 FlutterActivity 中的上下文，所以我不能将它更改为 FlutterFragmentActivity 或者我得到Unresolved reference: context

package app.masarifi

import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin


class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
//        GeneratedPluginRegistrant.registerWith(flutterEngine)
//
        GoogleMobileAdsPlugin.registerNativeAdFactory(
                flutterEngine, "listTile", ListTileNativeAdFactory(context))

        GoogleMobileAdsPlugin.registerNativeAdFactory(
                flutterEngine, "mediumAd", MediumNativeAdFactory(context))

    }

    override fun cleanUpFlutterEngine(flutterEngine: FlutterEngine) {
        super.cleanUpFlutterEngine(flutterEngine)

        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "listTile")
        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "mediumAd")
    }

}

更改 Context => applicationContext 来解决
