[SOLVED] Play music files from Phone's directory

Play music files from Phone's directory

I am developing an application where users can download songs and play them offline. These downloaded songs will remain within the app. I implement the download feature using flutter_downloader: ^1.10.2. Now I want to play that downloaded music in the app using audioplayers: ^3.0.1. How to load music from device storage in flutter?

  final player = AudioPlayer();

await player.play(DeviceFileSource(
                              'data/user/0/{appName}/app_flutter/{fileName}')

This code throws the error - Unexpected error! D/AudioPlayers(12795): java.io.FileNotFoundException: "myFilePath data/user/0/{appName}/app_flutter/{fileName} ": open failed: ENOENT (No such file or directory)

Solution

Here is solution for that, Maybe extension was the issue Process to save file

final dir = await getApplicationDocumentsDirectory();
var localPath = dir.path + name; //Name : Folder name

await dio.download({content URL},"$localPath/${YourFileName}.$extension",
       onReceiveProgress: (receivedBytes, totalBytes) {
     downloadPercentage.value = ((receivedBytes / totalBytes));
     //Further stuff
   });

Path will be - "$localPath/${YourFileName}.$extension"

Process to fetch file

await player.play(DeviceFileSource(
                              '$localPath/${YourFileName}.$extension')
