Flutter 音频播放器我的按钮没有'；不要在第一次单击时播放声音

我有一个按钮，当我点击它播放点击声音。在我的第一次单击中，它不会播放声音，第二次单击会播放声音，如果我等待3-4秒，然后再次单击按钮“无声音”。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')),
      ),
    );
  }
}

和其他类似的点击输出

试试这个

_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');

你在测试什么？你的wav文件有多大？我对你的密码没有问题。在我自己的手机上。5kb。我也看不出有什么问题。我想这可能是一个电话相关的情况。这是可能的。请查看我的答案，以找到一种提高性能的方法，从而解决您的问题。谢谢，它可以工作，但我想我会遇到错误或其他问题：）我更新了我的问题。他们有问题吗？

_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');
