所以我使用Flutter包audioplayers在我的应用程序上播放音频，但问题是导入包后，它说找不到play（）函数。
下面是代码：

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

void main() {
  runApp(const XlyophoneApp());
}

class XlyophoneApp extends StatelessWidget {
  const XlyophoneApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Center(
            child: TextButton(
              child: const Text('Click Me'),
              onPressed: () {
                final player = AudioCache();
                player.play("note1.wav"); // Here it says that the play function is not defined
              },
            ),
          ),
        ),
      ),
    );
  }
}
