        home: center(
          child: interactivepiano(
            highlightednotes: [
              noteposition(note: note.c, octave: 3)
            ],
            naturalcolor: colors.white,
            accidentalcolor: colors.black,
            keywidth: 60,
            noterange: noterange.forclefs([
              clef.treble,
            ]),
            onnotepositiontapped: (position) {
              // use an audio library like flutter_midi to play the sound
            },
          ),
        ));
  }
}
