Changing audio playback speed

Is there any way to change (increase/decrease) audio playback speed using Flutter?

Couldn't find any info about it and it seems like writing native code is the only option.

Try to use inappwebview package that will enable you to customize any Voice player using HTML Code by Sending it like that :

   initialUrlRequest: URLRequest(
          url: Uri.dataFromString(
              generateVoicePlayerHTML(voiceUrl),
              mimeType: 'text/html',
              encoding: Encoding.getByName('utf-8'))),

and you will create your Html Code inside abstract class "GenerateVoicePlayerHTML" also have many Attributes to use it depend on platform

The more complete example of using audioplayers:

import 'dart:developer';
import 'package:audioplayers/audioplayers.dart';

class Player {
   static play(String src, Function onComplete, {double playbackRate = 1.0}) async {
    try {
      final player = AudioPlayer();
      await player.setPlaybackRate(playbackRate);
      await player.play(AssetSource(src));
      player.onPlayerComplete.listen((_) {
        onComplete();
      });
    } catch (e, stack) {
      log(src);
      log(e.toString());
      log(stack.toString());
    }
  }  


}

Use like:

Player.play(pathToFile, () {}); //normal speed
Player.play(pathToFile, () {}, playbackRate: 0.7); //slowly
Player.play(pathToFile, () {}, playbackRate: 1.5); //quickly

Note that setPlaybackRate has no effect on the Windows app. I did not try an emulator but on a real Android device and the web on Chrome works fine.

The package audioplayers has incorporated support for playback rate:

_audioPlayer.setPlaybackRate(playbackRate: 1.0);

Try an audioplayers_with_rate fork of audioplayers. It worked great for me, but I couldn't find where its code is located (it links to audioplayers). The same functionality provides this fork or this fork of audioplayers.
