A widget that sizes its child to the child's intrinsic width.

Sizes its child's width to the child's maximum intrinsic width. If stepWidth is non-null, the child's width will be snapped to a multiple of the stepWidth. Similarly, if stepHeight is non-null, the child's height will be snapped to a multiple of the stepHeight.

This class is useful, for example, when unlimited width is available and you would like a child that would otherwise attempt to expand infinitely to instead size itself to a more reasonable width.

This class is relatively expensive. Avoid using it where possible.
