Expand description

A sliver with a box child which never scrolls off the viewport in the positive scroll direction, and which first scrolls on at a full size but then shrinks as the viewport continues to scroll.

This sliver avoids overlapping other earlier slivers where possible.

Required Methods§

Source

fn pinned_data( self: RenderHandle<Self>, app: &App, ) -> &RenderSliverPinnedPersistentHeaderData

Mixin field access.

Source

fn pinned_data_mut( self: RenderHandle<Self>, app: &mut App, ) -> &mut RenderSliverPinnedPersistentHeaderData

See pinned_data.

Provided Methods§

Source

fn perform_layout(self: RenderHandle<Self>, app: &mut App)

The body of Flutter’s performLayout override.

Source

fn child_main_axis_position( self: RenderHandle<Self>, _app: &App, _child: AnyRenderObject, ) -> f64

The body of Flutter’s childMainAxisPosition override.
