buildWithChild method
A build method that receives an extra child
parameter.
This method may be called with a child
different from the parameter
passed to the constructor of SingleChildStatelessModifier.
It may also be called again with a different child
, without this widget
being recreated.

opacity: opacity,
alwaysIncludeSemantics: alwaysIncludeSemantics,
sliver: child,
);
