RenderIntrinsicWidth constructor
Creates a render object that sizes itself to its child's intrinsic width.
If stepWidth
is non-null it must be > 0.0. Similarly If stepHeight
is
non-null it must be > 0.0.
Implementation
RenderIntrinsicWidth({
double? stepWidth,
double? stepHeight,
RenderBox? child,
}) : assert(stepWidth == null || stepWidth > 0.0),
assert(stepHeight == null || stepHeight > 0.0),
_stepWidth = stepWidth,
_stepHeight = stepHeight,
super(child);
