问题 未为“AudioCache”类型定义“play”方法。
导入“包：flutter/material.dart”；导入'包：audioplayers/src/audio_cache.dart'；

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

class XylophoneApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
  home: Scaffold(
    body: SafeArea(
      child: Center(
        child: TextButton(
          onPressed: () {
            final player = AudioCache();
            player.play('note1.wave');
          },
          child: Text('click me'),
        ),
      ),
    ),
  ),
 );
}

}
