There is a problem with onRecorderStateChanged on ios

When I first record and play what I just recorded, and then I click on record again, onRecorderStateChanged has a 0 result all the way and cannot be recorded ‘’’ import ‘dart:io’;

import ‘package:chongmeng/constants/constants.dart’; import ‘package:chongmeng/utils/date_utils.dart’; import ‘package:flutter/material.dart’; import ‘package:flutter_sound/flutter_sound_player.dart’; import ‘package:flutter_sound/flutter_sound_recorder.dart’; import ‘package:intl/intl.dart’; import ‘package:path_provider/path_provider.dart’;

class PlayPage extends StatefulWidget { @override _PlayPageState createState() => _PlayPageState(); }

class _PlayPageState extends State<PlayPage> { FlutterSoundPlayer soundPlayer; FlutterSoundRecorder soundRecorder; var recorderSubscription; var result;

@override void initState() { super.initState(); init(); }

init() async { soundPlayer = await FlutterSoundPlayer().initialize(); soundRecorder = await FlutterSoundRecorder().initialize(); }

void _onStartRecord() async { showToast(“_onStartRecord”); Directory tempDir = await getTemporaryDirectory(); File outputFile = File(‘${tempDir.path}/${DateUtils.currentTimeMillis()}.aac’); result = outputFile.path; String a = await soundRecorder.startRecorder(uri: outputFile.path);

recorderSubscription = soundRecorder.onRecorderStateChanged.listen((e) {
  DateTime date =
      new DateTime.fromMillisecondsSinceEpoch(e.currentPosition.toInt());
  String txt = DateFormat('mm:ss:SS', 'en_US').format(date);

// if (txt.contains(“00:02”)) { // _onStopRecord(); // } }); soundRecorder.onRecorderDbPeakChanged.listen((value) { print(“got update -> $value”); }); }

Future<void> _onStopRecord() async { showToast(“_onStopRecord”); print("_onStopRecord "); String localUrl = await soundRecorder.stopRecorder(); if (recorderSubscription != null) { recorderSubscription.cancel(); recorderSubscription = null; } }

@override void dispose() { soundRecorder.release(); soundPlayer.release(); super.dispose(); }

_onStartPlay() async { showToast(“_onStartPlay”); soundPlayer.startPlayer(this.result); }

@override Widget build(BuildContext context) { return Container( child: Column( children: <Widget>[ IconButton( icon: Icon(Icons.record_voice_over), onPressed: () { _onStartRecord(); }, ), Padding( padding: const EdgeInsets.symmetric(vertical: 24), child: RaisedButton( child: Text(“OK”), onPressed: () { _onStopRecord(); }, ), ), IconButton( icon: Icon(Icons.play_arrow), onPressed: () { _onStartPlay(); }, ), ], ), ); } }

Hi @Gibsouille ,

could you look to V 4.0.5 and see if better ?

Hi @zhangruiyu , I am glad that the issue is fixed. I am really sorry for the delay : the problem occurred on real devices and not the simulator. It was not easy for us to debug that.

Good luck, using Flutter Sound. 😄
