Fingerprint authentication is not working in flutter

@override
Widget build(BuildContext context) {
return Scaffold(

body: Scaffold(

}
}
This is my code where I am using flutter_screen_lock library to show the lock screen everything is working properly here but when i add code for fingerprint authentication it started getting exception so I google for it then I found solution of it where they said after changing FlutterActivity with FlutterFragmentActivity it'll solve my issue..
Here is my MainActivity:
package com.pawarsproduction.secret_keeper
import io.flutter.embedding.android.FlutterFragmentActivity
class MainActivity: FlutterFragmentActivity() {
}
after changing this my problem not solved but started getting many exceptions:
