Vertical Alignment for Individual Layout Item A particular layout item can be vertically aligned itself to start, center, or end, ignoring the vertical aligment on the layout level.
Important Notes: If vertical alignment is set, layout items cannot match each other’s height even if 100% height is used. Do not use this prop if equal height layout items are desired.This prop is only effective in a multi-column layout.For regular options, they are only effective when applied to the shorter item.For advanced usage, the offset options can even offset the top or bottom padding of the layout. This is useful when a design calls for a layout item to touch the edge of the layout.If you intend to vertically align all layout items uniformly, please use the prop on the layout level.
