A sliver that remains âpinnedâ to the top of the scroll view. Subsequent slivers scroll behind it. Typically the sliver is created as the first item in the list however it can be inserted anywhere and it will always stop at the top of the scroll view. When the scrolling axis is vertical, the PinnedHeaderSliverâs height is defined by its widget child. Multiple PinnedHeaderSlivers will layout one after the other, once they've scrolled to the top. This sliver is preferable to the general purpose SliverPersistentHeader - for its relatively narrow use case - because there's no need to create a [SliverPersistentHeaderDelegate] or to predict the header's size. Here's a [working demo in DartPad](https://dartpad.dev/?id=3b3f24c14fa201f752407a21ca9c9456). https://github.com/flutter/flutter/assets/1377460/943f2e02-8e73-48b7-90be-61168978ff71 Related sliver utility PRs: https://github.com/flutter/flutter/pull/143538, https://github.com/flutter/flutter/pull/143325, https://github.com/flutter/flutter/pull/127340. |
