我使用這個包：
youtube_explode_dart
我找到了這種下載視頻的方法
Future<void> downloadVideo(id) async {
var permisson = await Permission.storage.request();
if (permisson.isGranted) {
//download video
if (_urlTextFieldController.text != '') {
setState(() => _downloading = true);
//download video
setState(() => progress = 0);
var _youtubeExplode = YoutubeExplode();
//get video metadata
var video = await _youtubeExplode.videos.get(id);
var manifest =
await _youtubeExplode.videos.streamsClient.getManifest(id);
var streams = manifest.muxed.withHighestBitrate();
var audio = streams;
var audioStream = _youtubeExplode.videos.streamsClient.get(audio);
//create a directory
Directory appDocDir = await getApplicationDocumentsDirectory();
String appDocPath = appDocDir.path;
var file = File('$appDocPath/${video.id}');
//delete file if exists
if (file.existsSync()) {
file.deleteSync();
}
var output = file.openWrite(mode: FileMode.writeOnlyAppend);
var size = audio.size.totalBytes;
var count = 0;
await for (final data in audioStream) {
// Keep track of the current downloaded data.
count = data.length;
// Calculate the current progress.
double val = ((count / size));
var msg = '${video.title} Downloaded to $appDocPath/${video.id}';
for (val; val == 1.0; val ) {
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text(msg)));
}
setState(() => progress = val);
// Write to file.
output.add(data);
}
} else {
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(content: Text('add youtube video url first!')));
setState(() => _downloading = false);
}
} else {
await Permission.storage.request();
}
}
當方法完成時 Scaffold Messenger 發送訊息視頻 wad 已下載，但我無法在圖庫或本地存盤中找到視頻
我使用的是真實設備 Android，我將所有權限添加到 Android 清單。
任何人都可以幫助我:(
uj5u.com熱心網友回復：
原因可能是您正在使用 path_provider 函式“getApplicationDocumentsDirectory()”來存盤檔案。通過將上述函式替換為“getExternalStorageDirectory()”，您可以將檔案存盤在外部目錄中以顯示在圖庫中。如果這不起作用，您還可以使用此插件： https ://pub.dev/packages/gallery_saver
