GrowthDirection enum

The direction in which a sliver's contents are ordered, relative to the scroll offset axis.

For example, a vertical alphabetical list that is going AxisDirection.down with a GrowthDirection.forward would have the A at the top and the Z at the bottom, with the A adjacent to the origin, as would such a list going AxisDirection.up with a GrowthDirection.reverse. On the other hand, a vertical alphabetical list that is going AxisDirection.down with a GrowthDirection.reverse would have the Z at the top (at scroll offset zero) and the A below it.

The direction in which the scroll offset increases is given by applyGrowthDirectionToAxisDirection.

Constants

forward → const GrowthDirection

This sliver's contents are ordered in the same direction as the AxisDirection.

reverse → const GrowthDirection

This sliver's contents are ordered in the opposite direction of the AxisDirection.

const GrowthDirection(1)
values → const List<GrowthDirection>

A constant List of the values in this enum, in order of their declaration.

const List<GrowthDirection>
