what is difference between spacing and run space named parameter Flutter Wrap() Widget and also run alignment property please explain that
spacing is the space between the children in the main axis and
runSpacing is the space in the cross axis.
Consider this example (for default alignment)
SizedBox( width: 300, child: Wrap( spacing: 20.0, // Horizontal space. runSpacing: 30.0, // Vertical space. children: <Widget>[ apple, ball, champion, destructor, eagle, ], ), )
