PlatformException on starting recorder with flutter_sound

This is my code:

import 'package:audio_session/audio_session.dart';
import 'package:flutter/material.dart';
import 'package:flutter_sound/flutter_sound.dart';
import 'package:flutter_sound_platform_interface/flutter_sound_recorder_platform_interface.dart';
import 'package:path_provider/path_provider.dart';

class MicTest {

  static FlutterSoundRecorder? _mRecorder = FlutterSoundRecorder();

  static Codec _codec = Codec.aacMP4;

  static const theSource = AudioSource.microphone;

  static void startRecorder() async {
    await _mRecorder!.openRecorder();
    final session = await AudioSession.instance;
    await session.configure(AudioSessionConfiguration(
      avAudioSessionCategory: AVAudioSessionCategory.playAndRecord,
      avAudioSessionCategoryOptions:
      AVAudioSessionCategoryOptions.allowBluetooth |
      AVAudioSessionCategoryOptions.defaultToSpeaker,
      avAudioSessionMode: AVAudioSessionMode.spokenAudio,
      avAudioSessionRouteSharingPolicy:
      AVAudioSessionRouteSharingPolicy.defaultPolicy,
      avAudioSessionSetActiveOptions: AVAudioSessionSetActiveOptions.none,
      androidAudioAttributes: const AndroidAudioAttributes(
        contentType: AndroidAudioContentType.speech,
        flags: AndroidAudioFlags.none,
        usage: AndroidAudioUsage.voiceCommunication,
      ),
      androidAudioFocusGainType: AndroidAudioFocusGainType.gain,
      androidWillPauseWhenDucked: true,
    ));
    print("initialized");
    String _mPath = 'tau_file.mp4';
    var tempPath = await getTemporaryDirectory();
    _mPath = tempPath.path + "/" + _mPath;
    _mRecorder!
        .startRecorder(
      toFile: _mPath,
      codec: _codec,
      audioSource: theSource,
    )
    .then((value) {
      //setState(() {});
    });
  }

  static void stopRecorder() async {
    await _mRecorder!.stopRecorder().then((value) {
      // setState(() {
      //   //var url = value;
      //   _mplaybackReady = true;
      // });
    });
  }
}

When I call MicTest.startRecorder() I get:

I've just started using flutter_sound, so I think the problem is in my code. Could anyone say how to fix this problem?

The solution is to just import

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

instead of

import 'package:flutter_sound/flutter_sound.dart';

from the same flutter_sound package.

However, I suggest you to use another package for recording audio because flutter_sound seems like an abandoned package.

My choice for now is this record package.

Here is how to implement record package with ease.
