Adding Audio/sound in Flutter

Adding Audio/Sound in Flutter

First, Add dependencies:

dependencies:
  audioplayers: ^0.18.3

Now, run an implicitdart pub get.
Note: Install the latest version.

Import it
Now in your Dart code, you can use:

import 'package:audioplayers/audioplayers.dart';

import 'package:audioplayers/audio_cache.dart';

Play Sound/Audio after you open the app:

AudioPlayer advancedPlayer;

Future loadMusic() async {
    advancedPlayer = await AudioCache().loop("filename.mp3");    //to play audio in a loop
                //OR
    advancedPlayer = await AudioCache().play("filename.mp3");    //to play audio once
}
@override
void initState() {
      loadMusic();
      super.initState();
}

To Stop Sound/Audio:

Future stopp(){        //created stopp() function to stop playing audio
  advancedPlayer.stop();
}

To Play/Stop Sound on a click on a icon:

class _HomeScreen extends State<HomeScreen>{
Icon icon1 = Icon(    //to change icon onPressed:
  Icons.volume_up,
);
        
bool on = true;     

@override
Widget build(BuildContext context) {
  return Scaffold(
      appBar: AppBar(title: Text("APP TITLE"),
        centerTitle: true,
      actions: [
        IconButton(icon: icon1, onPressed: (){
        setState(() {   
          if(on){    //stops playing audio onPressed:
            stopp();       
            icon1 = Icon( Icons.volume_off,);
            on = !on;
          }
          else{    //starts playing audio onPressed:
            loadMusic();    
            icon1 = Icon( Icons.volume_up,);
            on = !on;
          } 
        });
       }),     //IconButton
    ],),      //AppBar
   );        //Scaffold  
 }
}
