Unhandled Exception: Instance of '_RecorderRunningException' flutter_sound_lite

Question

I am using flutter sound lite library what I wanna do is to record the sound and then play the recorded sound so i wrote the following code

importing the library

import 'package:flutter_sound_lite/public/flutter_sound_recorder.dart';

Class to record the sound start_recorder.dart

class SoundRecorder{
  FlutterSoundRecorder? _audioRecorder;
  bool _isRecorderInitialised= false;
  bool isRecording=false;
  
  //init method
  Future init() async{
    _audioRecorder= FlutterSoundRecorder();
    final status= await Permission.microphone.request();
    if(status!= PermissionStatus.granted){
      throw RecordingPermissionException('Microphone permission not granted');
    }
    await _audioRecorder!.openAudioSession();
    _isRecorderInitialised=true;
  }

  //dispose method

  void dispose(){
    if(!_isRecorderInitialised) return;
    _audioRecorder!.closeAudioSession();
    _audioRecorder=null;
    _isRecorderInitialised=false;
  }

  //record method to record sound
  Future _record() async{
    if(!_isRecorderInitialised) return;
    try{
      await _audioRecorder!.startRecorder(toFile:pathToSaveAudio );
    }
    catch (e)
    {
      throw e;
    }


  }
  
  //stop method to stop recording sound

  Future _stop() async {
    if(!_isRecorderInitialised) return;
    await _audioRecorder!. startRecorder();

  }
  Future toggleRecording() async{
    if(_audioRecorder!.isStopped){
      isRecording=true;
      await _record();
    }
    else{
      isRecording=false;
      await _stop();
    }
  }


}

Main.dart

now in main state elevatedButton is a child of a container

Container(
            child:  ElevatedButton.icon(
              style: ElevatedButton.styleFrom(
                  minimumSize: Size(175, 50),
                  primary: primary,
                  onPrimary: onPrimary
              ),
              icon: Icon(icon),
              label: Text(
                text,
                style: TextStyle(fontSize: 16,fontWeight: FontWeight.bold),
              ),
              onPressed: () async{
                final isRecording= await recorder.toggleRecording();
                setState(() {

                });
              },

            ),

          )
