How to get length of audio file without playing it in Flutter/Dart

Question

I'm trying to display the length of audio files in my Flutter application. I've used both the flutter_sound and audioplayers plugins but I'm not sure how to get the length of the audio file without playing it and getting the duration (which I want to display the length of each audio file in a list so users know how long it is before playing). I haven't been able to find anywhere online that shows how to get the audio file length in dart except from using the duration of the playing audio file in one of those plugins. Anyone know how to get audio file length's in dart?

Answer 1

This is a late answer but incase if you are still wondering how to do that, There is a audio library just_audio

final player = AudioPlayer();
var duration = await player.setUrl('file.mp3');

Works on both android and IOS, supports both local files and download urls.
