Features

Usage

To draw a simple guitar fretboard you can just instantiate the Fretboard widget passing some Size and a matrix that represents how the fretboard should be drawn:

class MyCustomWidget extends StatelessWidget {
  const MyCustomWidget({super.key});

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Fretboard(
        size: Size(400, 240),
        notesMatrix: [
          ['', 'o', '', '', 'o', ''],
          ['', 'o', '', '', 'o', ''],
          ['', 'o', '', 'o', '', ''],
          ['', 'o', '', '0', '', ''],
          ['', 'o', '', '', 'o', ''],
          ['', '0', '', '', 'o', ''],
        ],
      ),
    );
  }
}

Advanced usage

Custom theme

You can change the default theme colors by passing a custom FretboardTheme:

Fretboard(
  size: Size(400, 240),
  theme: FretboardTheme(
    tonicColor: Colors.green,
    noteColor: Colors.pink,
    fretColor: Colors.grey,
    stringColor: Colors.black,
  ),
  notesMatrix: [
    ['', 'o', '', '', 'o', ''],
    ['', 'o', '', '', 'o', ''],
    ['', 'o', '', 'o', '', ''],
    ['', 'o', '', '0', '', ''],
    ['', 'o', '', '', 'o', ''],
