Question

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)

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

Here is my Mainactivity.kt

package com.example.bio_met

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}

Solution

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);
    }
}

@TiziDev can show me logs while it's crashing. you see the logs in the android studio logcat tab on the bottom while running the app connect your phone to the system to see logs.
