rotationDeg property

double get rotationDeg

Derived rotation in degrees.

Note: for general affine transforms (shear), a unique decomposition into rotation+scale is not well-defined. This getter assumes a rotation+scale form and is intended as a convenience accessor.

Implementation

double get rotationDeg {
  final a = transform.a;
  final b = transform.b;
  if (a == 0 && b == 0) return 0;
  return math.atan2(b, a) * 180.0 / math.pi;
}

set rotationDeg (double value)

Implementation

set rotationDeg(double value) {
  transform = Transform2D.trs(
    translation: position,
    rotationDeg: value,
    scaleX: scaleX,
    scaleY: scaleY,
  );
}
