You need to call child for each TextButton like I am using Text widget on it

TextButton(
  onPressed: () {
    AudioCache player = AudioCache();
    player.play('assets_note1.wav');

    TextButton.styleFrom(foregroundColor: Colors.red);
  },
  child: Text("Button Name"), //this
),

add child property in TextButton like this

  TextButton(
            child: Text("Play"),
            onPressed: () {
              AudioCache player = AudioCache();
              player.play('assets_note2.wav');
              TextButton.styleFrom(foregroundColor: Colors.blue);
            },
  ),
