How to register your fingerprint and log in with your fingerprint

the same question...

Exception occurred as below, though I have added <uses-permission android:name="android.permission.USE_FINGERPRINT"/> to src/main/AndroidManifest.xml.

I/flutter (13327): PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null, null)

Resolved.

Use FlutterFragmentActivity instead of FlutterActivity in MainActivity.kt, and it works.

//import io.flutter.embedding.android.FlutterActivity
import androidx.annotation.NonNull
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)
    }
}
