A basic widget for adding Space in between the child of a Column/Row and all RenderFlex widgets descendants.
I wrote this small package while learning how Flutter RenderObject works. reference to followed tutorial, might help you get a hang of it.
The Widget should be used in a RenderFlex widget e.g Column/Row.
final someList = Column(children:
<Widget>[
Text("Some Text here"),
Gap(20)
Text("After some space text"),
],
) ;
Will add test in the next release.
