Piano

A Flutter package that provides:

• logic for working with musical notes, clefs and octaves;
• a widget that can render notes on a clef;
• an interactive piano widget.

Where is it used?

In "Learn The Notes", a simple sight reading trainer you can find on the iOS App Store here and macOS App Store here.

How do I use it?

Here's an example app:

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:piano/piano.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return CupertinoApp(
        title: 'Piano Demo',
        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
            },
          ),
        ));
  }
}
