我的按钮在第一次点击时不播放声音

Question

我有一个按钮，当我点击它播放，点击声音。在我的第一次点击它不播放声音，第二次点击播放声音，如果我等待3-4秒，并单击按钮没有声音再次。但总是点击打印。

import 'package:flutter/material.dart';
import 'package:audioplayers/audio_cache.dart';
import 'package:audioplayers/audioplayers.dart';

class MyButton extends StatefulWidget {
  @override
  _MyButtonState createState() => _MyButtonState();
}

class _MyButtonState extends State<MyButton> {
  AudioCache _audioCache;

  @override
  void initState() {
    super.initState();
    _audioCache = AudioCache(
        prefix: "assets/sounds/",
        fixedPlayer: AudioPlayer()..setReleaseMode(ReleaseMode.STOP));
  }
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        print('CLICKED');
        _audioCache.play('buttonClick.wav');
      },
      child: Container(
        height: 80,
        width: 80,
        decoration: BoxDecoration(
          color: Colors.green,
          shape: BoxShape.circle,
        ),
        child: Center(child: Text('CLICK ME')),
      ),
    );
  }
}

我已经试过答案了。没有声音问题，但:)当页面init在我的第一次单击控制台输出是

D/WSP     (16110): Reusing soundId1 for /data/user/0/com.example.myapp/cache/buttonClick.wav is loading=false xyz.luan.audioplayers.WrappedSoundPool@bfc7a44
V/AudioTrack(16110): start: server read:-8418  cumulative flushed:0  client written:0

和其他点击输出，如

I/flutter (16110): CLICKED
V/AudioTrack(16110): start: server read:-12627  cumulative flushed:0  client written:0
I/flutter (16110): CLICKED
V/AudioTrack(16110): start: server read:-14030  cumulative flushed:0  client written:0
I/flutter (16110): CLICKED
V/AudioTrack(16110): start: server read:-15433  cumulative flushed:0  client written:0
I/flutter (16110): CLICKED
V/AudioTrack(16110): start: server read:-16836  cumulative flushed:0  client written:0

Answer 1

尝尝这个。

_audioCache = AudioCache(
  prefix: "assets/sounds/",
  fixedPlayer: AudioPlayer(
    // set mode to LOW_LATENCY for better performance with short audio files
    mode: PlayerMode.LOW_LATENCY,
  )..setReleaseMode(ReleaseMode.STOP))
    // pre-cache the audio file so it doesn't have to load on first call
    ..load('buttonClick.wav');

Answer 2

如果您在使用AudioPlayers颤振包时遇到错误。

转到pubspec.yaml文件并加载资产中的所有声音。例如

flutter:
  assets:
    - assets/note1.wav
    - assets/youngpro.mp3
