operator + method

Vector3 operator +(
  1. dynamic v
)

Implementation

Vector3 operator +(dynamic v) {
  if (v is num) {
    return Vector3(x + v, y + v, z + v);
  } else if (v is Vector3) {
    return Vector3(x + v.x, y + v.y, z + v.z);
  } else {
    throw 'Vector3 only support addition by num or Vector3';
  }
}
