const { gradientangle } = attribute;
If a gradient fill is being used, this determines the angle of the fill. For linear fills, the colors transform along a line specified by the angle and the center of the object. For radial fills, a value of zero causes the colors to transform radially from the center; for non-zero values, the colors transform from a point near the object's periphery as specified by the value.
If unset, the default angle is 0.
