PlatformException（no_fragment_activity，local_auth插件要求活动为FragmentActivity。，null） [英] PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) in flutter

问题描述

我正在尝试使用 local_auth 颤振包我使用了相同的示例，因为包在这里。
并且我收到此错误

I am trying add Figureprint authentication using local_auth package of flutter i used same example given that package here it is. And i am getting this error

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

我已经尝试过解决方案，但问题是我不了解 kotlin 。

I have try this solution But the problem is that I don't know about kotlin.

这是我的 Mainactivity.kt

package com.example.bio_met

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}

推荐答案

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

I Found the answer and it worked for me. Here it is just replace your code with following code in MainActivity.kt file.

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);
    }
}
