LazyStackAxis

Enum LazyStackAxis 

Source
pub enum LazyStackAxis {
    Vertical {
        spacing: Computed<f32>,
        alignment: HorizontalAlignment,
    },
    Horizontal {
        spacing: Computed<f32>,
        alignment: VerticalAlignment,
    },
}
Expand description

The axis a LazyContainer can be virtualized along, together with the spacing and cross-axis alignment the stack was configured with.

Only the two stacks scroll in one direction with a well-defined item order, which is what viewport virtualization needs; every other layout — a grid, a ZStack, an absolute overlay — lays out its whole membership and returns None here.

Variants§
