SliverFillViewport class
A sliver that contains multiple box children that each fills the viewport.
To learn more about slivers, see CustomScrollView.slivers.
SliverFillViewport places its children in a linear array along the main axis. Each child is sized to fill the viewport, both in the main and cross axis.
See also:
- SliverFixedExtentList, which has a configurable SliverFixedExtentList.itemExtent.
- SliverPrototypeExtentList, which is similar to SliverFixedExtentList except that it uses a prototype list item instead of a pixel value to define the main axis extent of each item.
- SliverList, which does not require its children to have the same extent in the main axis.
