Use case / Problem

Hi everyone 🙂 I am developing a flutter app. It's an app that tests a student's proficiency of English as a second language. So there is one part to test oral comprehension. I use Audioplayers to do that part. I just finished it and everything works fine on android phones. I am just a beginner at programming. And I really loved how Audioplayers was easy to work with. But here is my problem : I just tried it on macbook to test on IOS... and catastrophe !! apparently, it's telling me : "SetSourceBytes is not currently implemented on IOS"... What can I do ? It's so handy to work with SourceBytes.

Do you think this feature will soon be available for IOS as well ?

Proposal / Solution

Unfortunaly as a beginner there is little I can offer as a solution.... Implementing support for SetSourceBytes on IOS would be a solution for my problem :)

Is it much more problematic than with Android phones ? What is the problem ?

I found one way to work around the problem.

1. I check platform : if ANDROID platform then, I use the SourceBytes system.

2. If IOS, then I download my file and store it in a Uint8list variable** "myAudioFileasBytes".

3. Using DART IO package : I create an empty file : myAudioFile = File('${(await getApplicationDocumentsDirectory()).path}/XXXXXX.mp3');

4. Then I actually 'write' the file from the stored Bytes : myAudioFile.writeAsBytes(myAudioFileasBytes);

5. Then with AudioPlayers : I use the DeviceFileSource method: await _player.play(DeviceFileSource('${(await getApplicationDocumentsDirectory()).path}/${myAudioFile}.mp3'));

I tried it on my iPhone and it worked.

Maybe it is somehow possible to override AVAsset to use a Audio AVAssetTrack with AVAudioBuffer. But that's only an assumption. Else we have to provide a workaround. AVAudioPlayer supports playing from a buffer.
