如何在 Flutter 中使用音频播放器插件播放本地 mp3 文件 [英] How to play local mp3 file with audioplayer plugin in Flutter

问题描述

如何在 Flutter 中使用 audioplayer 0.2.0 播放本地 mp3 文件.

How to play local mp3 file with audioplayer 0.2.0 in Flutter.

pubspec.yaml

pubspec.yaml

flutter:
    assets:
    - sounds/music.mp3

main.dart

Future<ByteData> loadAsset() async {
    return await rootBundle.load('sounds/music.mp3');
}

// FIXME: This code is not working.
Future playLocal() async {
    final result = await audioPlayer.play(loadAsset());
    if (result == 1) setState(() => playerState = PlayerState.playing);
}

我可以从 rootBundle 获取本地资产路径吗?我可以在 audioPlayer 上从 ByteData 支付音频吗?

Can I get local assets path from rootBundle? Can I pay audio from ByteData on audioPlayer?

推荐答案

audioplayer 插件目前仅支持网络路径和文件.您可以将资产移动到临时文件夹并使用以下代码播放:

The audioplayer plugin currently only supports network paths and files. You can move an asset to a temporary folder and play it with this code:

import 'package:path_provider/path_provider.dart';

...

final file = new File('${(await getTemporaryDirectory()).path}/music.mp3');
await file.writeAsBytes((await loadAsset()).buffer.asUint8List());
final result = await audioPlayer.play(file.path, isLocal: true);
