Redeclaration: ArCoreView

I am using ar_fluuter_plugin in my project. and I migrated the app to nullable using migrate tool.

after migration, while debugging the app, I am getting following error.

C:\Users\username\AppData\Local\Pub\Cache\hosted\pub.dartlang.org\arcore_flutter_plugin-0.0.11\android\src\main\kotlin\com\difrancescogianmarco\arcore_flutter_plugin\ArCoreView.kt: (33, 7): Redeclaration: ArCoreView e: C:\Users\username\AppData\Local\Pub\Cache\hosted\pub.dartlang.org\arcore_flutter_plugin-0.1.0-null-safety.3\android\src\main\kotlin\com\difrancescogianmarco\arcore_flutter_plugin\ArCoreView.kt: (44, 7): Redeclaration: ArCoreView

My code is like this:

import 'package:flutter/material.dart';
// ignore: import_of_legacy_library_into_null_safe
import 'package:arcore_flutter_plugin/arcore_flutter_plugin.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'ARCore Flutter Plugin Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'ARCore Flutter Plugin Example'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key? key, /*required*/ required this.title}) : super(key: key);

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  late ArCoreController arCoreController;
  void _onArCoreViewCreated(ArCoreController controller) {
    arCoreController = controller;
    arCoreController.onNodeTap = (name) => onTapHandler(name);
    arCoreController.onPlaneTap = _onPlaneTapHandler;
  }

  void onTapHandler(String name) {
    showDialog<void>(
      context: context,
      builder: (BuildContext context) =>
          AlertDialog(content: Text('onNodeTap on $name')),
    );
  }

  void _onPlaneTapHandler(List<ArCoreHitTestResult> hits) {
    var /*!*/ vector;
    var /*!*/ plane;
    final moonMaterial = ArCoreMaterial(color: Colors.grey);

    final moonShape = ArCoreSphere(
      materials: [moonMaterial],
      radius: 0.03,
    );

    final moon = ArCoreNode(
      shape: moonShape,
      position: vector.Vector3(0.2, 0, 0),
      rotation: vector.Vector4(0, 0, 0, 0),
    );

    final earthMaterial =
        ArCoreMaterial(color: Color.fromARGB(120, 66, 134, 244));

    final earthShape = ArCoreSphere(
      materials: [earthMaterial],
      radius: 0.1,
    );

    final earth = ArCoreNode(
        shape: earthShape,
        children: [moon],
        position: plane.pose.translation + vector.Vector3(0.0, 1.0, 0.0),
        rotation: plane.pose.rotation);

    arCoreController.addArCoreNodeWithAnchor(earth);
  }

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the App.build method, and use it to set our appbar title.
        title: Text(widget.title),
      ),
      body: ArCoreView(
        onArCoreViewCreated: _onArCoreViewCreated,
        enableTapRecognizer: true,
      ),
    );
  }
}

Please let me know, How can I fix it. Thanks in advance.

use this Prerelease: 0.1.0-null-safety.3 or remove null safety
