Struct SliverLayoutDimensions 

pub struct SliverLayoutDimensions {
    pub scroll_offset: f64,
    pub preceding_scroll_extent: f64,
    pub viewport_main_axis_extent: f64,
    pub cross_axis_extent: f64,
}

Relates the dimensions of the RenderSliver during layout.

Fields

scroll_offset: f64

Scroll offset in this sliver’s coordinate system of the earliest visible part of this sliver.

preceding_scroll_extent: f64

Scroll distance consumed by all slivers that came before this one.

viewport_main_axis_extent: f64

The number of pixels the viewport can display in the main axis.

For a vertical list, this is the height of the viewport.

cross_axis_extent: f64

The number of pixels in the cross-axis.

For a vertical list, this is the width of the sliver.
