toBar method

Offset toBar(
  1. Offset p
)

Maps platter coordinates (the bar's layout) to where they are drawn.

Implementation

Offset toBar(Offset p) {
  final Offset d = platterDrift;
  return Offset(
    _size.width / 2 + d.dx + (p.dx - _size.width / 2) * platterScaleX,
    _size.height / 2 + d.dy + (p.dy - _size.height / 2) * platterScaleY,
  );
}
