我目前正在使用audioplayers: ^0.20.1播放和恢復視頻，現在我想將音頻回圈 3 次（保持回圈播放音頻）。我知道audioplayers包有loop屬性，但我仍然不知道如何自定義loop屬性

以下是回圈音頻播放器的方法：
import 'package:audioplayers/audioplayers.dart';
import 'package:flutter/material.dart';
void main() {
runApp(MaterialApp(home: AudioPlayerLoopTesting()));
}
class AudioPlayerLoopTesting extends StatefulWidget {
@override
_AudioPlayerLoopTestingState createState() => _AudioPlayerLoopTestingState();
}
class _AudioPlayerLoopTestingState extends State<AudioPlayerLoopTesting> {
AudioCache audioCache = AudioCache();
@override
void initState() {
super.initState();
}
@override
void dispose() {
super.dispose();
}
void _playLoopAudio() {
int timesPlayed = 0;
const timestoPlay = 3;
//audio.mp3 is the local asset file
audioCache.play('audio.mp3').then((player) {
player.onPlayerCompletion.listen((event) {
timesPlayed ;
if (timesPlayed >= timestoPlay) {
timesPlayed = 0;
player.stop();
} else {
player.resume();
}
});
});
}
Widget localAsset() {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Text('Loop Local Asset'),
ElevatedButton(
child: const Text('Loop the audio'),
onPressed: _playLoopAudio,
),
],
);
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: localAsset(),
),
);
}
}
如果問題解決了請點贊

回圈音頻試試這個：-
static AudioCache musicCache;
static AudioPlayer instance;
void playLoopedMusic() async {
musicCache = AudioCache(prefix: "audio/");
instance = await musicCache.loop("bgmusic.mp3");
// await instance.setVolume(0.5); you can even set the volume
}
void pauseMusic() {
if (instance != null) {
instance.pause(); }}
僅回圈 3 次：-
int numberOftimesToPlay=0;
playThreeTimes(){
_audioPlayer = AudioPlayer();
int res = await _audioPlayer.play("https://192.168.1.66/$sUrl");
//await _audioPlayer.play("http://192.168.1.5/00001.mp3");
if (res == 1 & numberOftimesToPlay>4) {
numberOftimesToPlay ;
playThreeTimes()
print("ok");
} else {
print("done");
}}
