equilateralTriangleWidth property
If non-null, equilateralTriangleWidth defines the width of the shadow.
Note that this would only affect when clipper is set to Clipper.equilateral. The formula for shadow width is -> (width - childWidth) / 2 + equilateralTriangleWidth
equilateralTriangleWidth defaults to 5.
Implementation
final double equilateralTriangleWidth;
