Flutter Audio Cache Error with player.play

Question

Hi this code works wonderfully with Angela in my Flutter course haha but for some reason the player.play('notes1.wav') isnt working for me.. tips? I'm getting this error..

error: The method 'play' isn't defined for the type 'Type'. (undefined_method at [xylophone] lib/main.dart:17)

import 'package:flutter/material.dart';
import 'package:audioplayers/audio_cache.dart';

void main() => runApp(XylophoneApp());

class XylophoneApp extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Center(
            child: FlatButton(
              onPressed: () {
                final player = AudioCache;
                player.play('note1.wav');
              },
              child: Text('Click Me'),
            ),
          ),
        ),
      ),
    );
  }
}

I'm working on the same course! You've got the opening/closing brackets missing on the AudioCache declaration. It should be:

  final player = AudioCache();

I'd also do this for playing the audio, as it will stop making a sound after you press a few buttons:

    player.play('note$note.wav',
      mode: PlayerMode.LOW_LATENCY, 
      stayAwake: false);

It's better than the original code, but not perfect. I think there are audio 32 channels that get used up quite quickly - the about change seems to release them a bit quicker. Good luck with the rest of the course!
