Trying to delete an audio file but giving exception in flutter - flutter

Question

I'm trying to delete song file but it is unable to delete and throws an exception of permission denied but permissions are already granted using permission_handler and required storage permissions are added in AndroidManifest.xml as well. I have also checked path is valid and file exist before delete which return true. Would anyone help me to solve this.
Error on file.delete() line.
Unhandled Exception: FileSystemException: Deletion failed, path = '/storage/0E15-2E06/Music/Call Sound Effect.mp3' (OS Error: Permission denied, errno = 13)
AndroidManifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
<application
android:label="Example"
android:name="${applicationName}"
android:icon="#mipmap/ic_launcher"
android:usesCleartextTraffic="true"
android:requestLegacyExternalStorage="true" >
Code snippet:
if (await Permission.storage.request().isGranted) {
// Either the permission was already granted before or the user just granted it.
// permission was granted
if (song != null) {
String? path = song.data;
File file = File(path);
bool isExist = await file.exists();
if (isExist) {
await file.delete(recursive: true);
}
}
}

You have to use the permission_handler(https://pub.dev/packages/permission_handler) package and have to mention some permissions in the Androidmanifest.xml file.
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Also, you have to ask Permission of storage before doing storage related operation(In your case deletion of audio file).
final _permissionStatus = await Permission.storage.request();
if(_permissionStatus = PermissionStatus.isGranted){
/// Delete audio file
}else{
/// Permission Denied.
}
