getBounds method
Returns a bounds of the QR code symbol painted by paint, as an
axis-aligned Rect.
By default, this returns a rectangle that is the same size as the context estimated bounds. If shape paints a QR code symbol that is roughly the same size as the context bounds, then this may be adequate.
Implementation
Rect getBounds(PrettyQrPaintingContext context) {
return context.estimatedBounds;
}
