| |
| // In this sample the [SliverFillRemaining]'s child stretches to fill the |
| // overscroll area when [fillOverscroll] is true. This sample also features a |
| // button that is pinned to the bottom of the sliver, regardless of size or |
| // overscroll behavior. Try switching [fillOverscroll] to see the difference. |
| // |
| // This sample only shows the overscroll behavior on devices that support |
| // overscroll. |
