inherited

Flip the component vertically around its center line.

Implementation

void flipVerticallyAroundCenter() {
  if (anchor.y != 0.5) {
    final delta = (1 - 2 * _anchor.y) * height * transform.scale.y;
    transform.x += -delta * math.sin(transform.angle);
    transform.y += delta * math.cos(transform.angle);
  }
  transform.flipVertically();
}
