resolveRect method
Convert this instance into a floating-point rectangle whose coordinates are relative to a given QR module.
Implementation
Rect resolveRect(PrettyQrPaintingContext context) {
final canvasSize = context.estimatedBounds.longestSide;
final pointSize = canvasSize / context.matrix.dimension;
return Rect.fromLTWH(pointSize * x, pointSize * y, pointSize, pointSize);
}
