InheritedResponsiveWrapper class
Creates an immutable widget that exposes ResponsiveWrapperData to child widgets.
Access values such as the ResponsiveWrapperData.scaledWidth
property through ResponsiveWrapper.of
ResponsiveWrapper.of(context).scaledWidth.
Querying this widget with ResponsiveWrapper.of creates a dependency that causes an automatic rebuild whenever the ResponsiveWrapperData changes.
If no ResponsiveWrapper is in scope then the
MediaQuery.of method will throw an exception,
unless the nullOk argument is set to true, in
which case it returns null.
