canvas is the canvas to paint on. size is the size of the canvas.

Implementation

@override
void paint(Canvas canvas, Size size) {
  final center = Offset(size.width / 2, size.height / 2);
  final rect = Rect.fromCenter(
    center: center,
    width: width,
    height: height,
  );

  // Draw the filled rectangle
  final paint = Paint()
    ..color = color
    ..style = PaintingStyle.fill;

  if (cornerRadius != null) {
    canvas.drawRRect(
      RRect.fromRectAndRadius(rect, Radius.circular(cornerRadius!)),
      paint,
    );
  } else {
    canvas.drawRect(rect, paint);
  }

  // Draw the border if specified
  if (strokeWidth != null && strokeColor != null) {
    final borderPaint = Paint()
      ..color = strokeColor!
      ..style = PaintingStyle.stroke
      ..strokeWidth = strokeWidth!;

    if (cornerRadius != null) {
      canvas.drawRRect(
        RRect.fromRectAndRadius(rect, Radius.circular(cornerRadius!)),
        borderPaint,
      );
    } else {
      canvas.drawRect(rect, borderPaint);
    }
  }
}
