My Code :

package www.example.com;

import android.os.Bundle;

import io.flutter.app.FlutterActivity;

import io.flutter.plugin.common.StringCodec;

import io.flutter.plugins.GeneratedPluginRegistrant;

import io.flutter.plugin.common.MethodCall;

import io.flutter.plugin.common.MethodChannel;

import io.flutter.plugin.common.MethodChannel.MethodCallHandler;

import io.flutter.plugin.common.MethodChannel.Result;

import android.content.Context;

import android.app.KeyguardManager;

import android.view.WindowManager.LayoutParams;

public class MainActivity extends FlutterActivity {

  private static final String CHANNEL = "www.example.com/info";

  @Override

  protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    GeneratedPluginRegistrant.registerWith(this);

    getWindow().addFlags(LayoutParams.FLAG_SECURE);

    new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(new MethodCallHandler() {

      @Override

      public void onMethodCall(MethodCall call, MethodChannel.Result result) {

        if (call.method.equals("getDeviceStatus")) {

          KeyguardManager keyGuardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);

          result.success(keyGuardManager.inKeyguardRestrictedInputMode());

        }

      }

    });

  }

}
