PlatformException(no_fragment_activity，local_auth插件要求活动是 Fra

Question

我正在尝试使用颤振包添加 Figureprint 身份验证local_auth我使用了相同的示例，因为该包在这里。 我收到此错误

I/flutter (27676): PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)

我已经尝试了这个解决方案，但问题是我不了解kotlin。

这是我的主要活动.kt

package com.example.bio_met
import io.flutter.embedding.android.FlutterActivity
class MainActivity: FlutterActivity() {
}

Answer 1

我找到了答案，它对我有用。在这里，它只是将您的代码替换为MainActivity.kt文件中的以下代码。

package //your package name for eg.com.example.filename
import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine){
GeneratedPluginRegistrant.registerWith(flutterEngine);
}
}
