Hey guys, I love this project, could you explain me how to generate waves from an http audio url? I can't find any doc or example in the pub.dev link or by reading the sources.

To work around the problem I created a temporary file, but it would be nice to have a method to invoke fromUrl. I'm posting this code to help someone who would like to read voice messages from a database.

ElevatedButton(
    onPressed: () async {
        Response response = await get(Uri.parse(
            "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3"));
        Uint8List bytes = response.bodyBytes;
        File file = File('${appDirectory.path}/audio1.mp3');

        if (response.statusCode == 200) {
              await file.writeAsBytes(bytes);
               playerController1.preparePlayer(file.path).then((value) {
                    if (mounted) {
                        setState(() {});
                    }
             });
       }
 },
child: Text("Buf url"),
 ),
