我正在编写一个使用 flutter_sound 包录制语音的 flutter 应用程序

environment:
  sdk: ">=2.15.1 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.2
  flutter_sound: ^9.1.2
  permission_handler: ^8.3.0

import 'package:flutter_sound/flutter_sound.dart';
import 'package:permission_handler/permission_handler.dart';

Future init() async {
    _audioRecorder = FlutterSoundRecorder();

    final status = await Permission.microphone.request();
    if (status != PermissionStatus.granted){
      throw RecordingPermissionException('Microphone permission denied.');
    }
    await _audioRecorder!.openAudioSession();
    _isRecorderInitiated = true;
 }

我收到这个错误

The method 'openAudioSession' isn't defined for the type 'FlutterSoundRecorder'.

有人能帮我找出代码有什么问题吗？
