LimitedBox constructor

const LimitedBox({Key key, double maxWidth: double.infinity, double maxHeight: double.infinity, Widget child })

Creates a box that limits its size only when it's unconstrained.

The maxWidth and maxHeight arguments must not be null and must not be negative.

Implementation 

const LimitedBox({
  Key key,
  this.maxWidth = double.infinity,
  this.maxHeight = double.infinity,
  Widget child,
}) : assert(maxWidth != null && maxWidth >= 0.0),
     assert(maxHeight != null && maxHeight >= 0.0),
     super(key: key, child: child);
