如何根据用户手机方向向左或向右翻转flutter应用程序？

import 'package:flutter/material.dart';
import 'package:sensors/sensors.dart';

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  double _rotation = 0.0;

  @override
  void initState() {
    super.initState();
    accelerometerEvents.listen((AccelerometerEvent event) {
      setState(() {
        if (event.x < -1.0) {
          // 向左翻转
          _rotation = -0.5;
        } else if (event.x > 1.0) {
          // 向右翻转
          _rotation = 0.5;
        } else {
          _rotation = 0.0;
        }
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Flip'),
        ),
        body: Center(
          child: Transform(
            alignment: Alignment.center,
            transform: Matrix4.rotationZ(_rotation),
            child: Container(
              width: 200,
              height: 200,
              color: Colors.blue,
              child: Center(
                child: Text(
                  'Flip me!',
                  style: TextStyle(
                    fontSize: 24,
                    color: Colors.white,
                  ),
                ),
              ),
            ),
          ),
        ),
      ),
    );
  }
}
