У меня есть приложение flutter, в котором моя задача-регистрировать события пользователей с помощью событий приложения facebook. Я добавил следующий пакет в свой pubspec.yaml:

 facebook_app_events: ^0.14.7  

Добавлено следующее в build.gradle:

 buildscript {  ext.kotlin_version = '1.5.10'  repositories {  google()  jcenter()  mavenCentral() //**Added as per fb docs  }  

Добавлено следующее в app/build.gradle:

 dependencies {  implementation 'com.facebook.android:facebook-android-sdk:latest.release'  }  

В AndroidManifest я добавил следующие метаданные:

 lt;application  ..//  lt;meta-data android:name="com.facebook.sdk.ApplicationId"  android:value="app id"/gt;     lt;/applicationgt;  

Позже, в своих представлениях о трепете, я сделал следующую реализацию:

 static final facebookSDK = FacebookAppEvents();  TextButton(  onPressed: () {  facebookSDK.logEvent(  name: 'button_clicked',  parameters: {  'button_id': 'the_clickme_button',  },  );  },  child: Text("Trigger Payment Info Click")),  

Когда я нажимаю эту кнопку, я получаю следующую ошибку вместо отправки события входа в fb:

I deleted .gradle folder, ran flutter clean still no help. I do not know much about native kotlin. Any sort of help will be appreciated.
