class _HomeState extends State<Home> {
  String currentAlphabet = "A";
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.amber[200],
      body: LayoutBuilder(builder: (context, constraints) {
        var height = constraints.maxHeight;
        var width = constraints.maxWidth;
        return Column(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            sentenceHolder(height, width),
            Row(
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: [
                imageHolder(height, width),
                wordHolder(height, width),
              ],
            ),
            Container(
              decoration:
                  BoxDecoration(borderRadius: BorderRadius.circular(15)),
              child: Wrap(
                children: changePos(),
              ),
            ),
          ],
        );
      }),
    );
  }

  playAudio(String path) {
    Player.asset(path).play();
  }

  List<Widget> changePos() {
    List<Widget> children = [
      ...alphabets
          .map(
            (e) => textHolder(e),
          )
          .toList()
    ];

    return children;
  }

Widget textHolder(String alphabet) {
    return Padding(
      padding: const EdgeInsets.all(7),
      child: ElevatedButton(
        onPressed: () {
          currentAlphabet = alphabet;
          playAudio("assets/audio/$alphabet.wav");
          setState(() {});
        },
        child: Text(alphabet),
      ),
    );
  }

// When calling a letter sound is a function

It works normally, but if we move quickly between the letter buttons, we notice that all the sounds work together at the same time //

Solution

class _HomeState extends State<Home> {
  AudioPlayer _audioPlayer;
  @override
  void initState() {
    _audioPlayer = AudioPlayer();
    // TODO: implement initState
    super.initState();
  }

  @override
  void dispose() {
    // _audioPlayer.dispose();
    super.dispose();
  }

  void _playAudio(String assetPath) async {
    _audioPlayer.pause();
    assetPath = ("assets/audio/$currentAlphabet.mp3");
    try {
      await _audioPlayer.setAsset(assetPath);
      _audioPlayer.play();
    } catch (e) {
      debugPrint("Error loading audio source: $e");
    }
  }}

i solved by using just_audio:
