Hey there Hope you can help me out. I’m using the following code in my main.dart file:
String _platformVersion = 'Unknown'; bool isPlaying = false; Duration _duration; Duration _position; double _slider; double _sliderVolume; String _error; num curIndex = 0; PlayMode playMode = AudioManager.instance.playMode;
final list = [ { "title": "Assets", "desc": "local assets playback", "url": "assets/audio.mp3", "coverUrl": "assets/ic_launcher.png" }, { "title": "network", "desc": "network resouce playback", "url": "https://dl.espressif.com/dl/audio/ff-16b-2c-44100hz.m4a", "coverUrl": "https://homepages.cae.wisc.edu/~ece533/images/airplane.png" } ];
@override
void initState() {
super.initState();
initPlatformState(); setupAudio(); // loadFile();
}
@override void dispose() { // 释放所有资源 AudioManager.instance.stop(); super.dispose(); }
void setupAudio() {
List _list = [];
list.forEach((item) => _list.add(AudioInfo(item["url"],
title: item["title"], desc: item["desc"], coverUrl: item["coverUrl"])));
AudioManager.instance.audioList = _list; AudioManager.instance.intercepter = true; AudioManager.instance.play(auto: false); AudioManager.instance.onEvents((events, args) { print("$events, $args"); switch (events) { case AudioManagerEvents.start: print("start load data callback"); _position = AudioManager.instance.position; _duration = AudioManager.instance.duration; _slider = 0; setState(() {}); break; case AudioManagerEvents.ready: print("ready to play"); _error = null; _sliderVolume = AudioManager.instance.volume; _position = AudioManager.instance.position; _duration = AudioManager.instance.duration; setState(() {}); // if you need to seek times, must after AudioManagerEvents.ready event invoked // AudioManager.instance.seekTo(Duration(seconds: 10)); break; case AudioManagerEvents.seekComplete: _position = AudioManager.instance.position; _slider = _position.inMilliseconds / _duration.inMilliseconds; setState(() {}); print("seek event is completed. position is [$args]/ms"); break; case AudioManagerEvents.buffering: print("buffering $args"); break; case AudioManagerEvents.playstatus: isPlaying = AudioManager.instance.isPlaying; setState(() {}); break; case AudioManagerEvents.timeupdate: _position = AudioManager.instance.position; _slider = _position.inMilliseconds / _duration.inMilliseconds; setState(() {}); AudioManager.instance.updateLrc(args["position"].toString()); break; case AudioManagerEvents.error: _error = args; setState(() {}); break; case AudioManagerEvents.ended: AudioManager.instance.next(); break; case AudioManagerEvents.volumeChange: _sliderVolume = AudioManager.instance.volume; setState(() {}); break; default: break; } });
}
Now when I’m playing next song for example setstate will refresh my whole app. How can I only rebuild a specific file of my project when event is triggered?
For example let’s say we have main.dart file home.dart , news.dart and on event AudioManagerEvents.next I only want setstate for my file News.dart, how to do this?
Thank you for the help!
