SliverPaddingModifier class
A sliver that applies padding on each side of another sliver.
Slivers are special-purpose widgets that can be combined using a CustomScrollView to create custom scroll effects. A SliverPadding is a basic sliver that insets another sliver by applying padding on each side.
Applying padding in the main extent of the viewport to slivers that have scroll effects is likely to have
undesired effects. For example, wrapping a SliverPersistentHeader with
pinned:true will cause only the appbar to stay pinned while the padding will scroll away.
