您的主活动类com.example.eres.MainActivity不是子类FlutterFragmentActivity

Question

我在颤振应用中实现了条形支付系统，我出错了

PlatformException (PlatformException(flutter_stripe initialization failed, The plugin failed to initialize:
Your Main Activity class com.example.eres.MainActivity is not a subclass FlutterFragmentActivity.
Please make sure you follow all the steps detailed inside the README: https://github.com/flutter-stripe/flutter_stripe#android
If you continue to have trouble, follow this discussion to get some support https://github.com/flutter-stripe/flutter_stripe/discussions/538, null, null))

当我运行app时，什么会导致这个错误，我在下面发送另一个文件，错误出现在等待Stripe.instance.applySettings()所在的位置，如果我删除它，我会再次得到相同的错误。

Main.dart -主要功能

void main() async {
  HttpOverrides.global = new MyHttpOverrides();
  WidgetsFlutterBinding.ensureInitialized();

  Stripe.publishableKey =
      "pk_test_51LS4cRFZdZe5rLR6wpNk9gLGUxCtdm8kIaymO3CifwTxihGUdSTyRmIl0ipk4rYMfHTdNVBoBmgLbSpCP6IrCzV500wcxqU1Hv";
  await Stripe.instance.applySettings();

  runApp(MyApp());
}

如果您对此有任何建议，请评论，非常感谢。

在你的安卓的MainActivity文件中，它应该扩展FlutterFragmentActivity。AppFolder -> Android ->应用程序-> src -> kotlin -> com.xxx.xxx -> MainActivity

class MainActivity : FlutterFragmentActivity() {
    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) 
    {
        // Your code
    }
}
