<STACK/> : <BOX/>
The <STACK/> widget layers its children one on top of the next starting from the first child specified. Children are positioned at x,y coordinate 0,0 by default. Positioned children need to be wrapped insize of a <POSITIONED/> widget.
Consider using a <ROW/> or <COLUMN/> widget for layout's which do not require widget overlay.
| Name | Type | Default | Description | Req |
|---|---|---|---|---|
| layout | string | stack | Fixed. Cannot be changed. | |
| expand | bool | true | If the widget expands to fill its parent, or shrinks to fit its children. By default, <STACK/> expands both horizontally and vertically to fill the available space. If either of the available vertical or horizontal space is infinite, typically when wrapped in a <SCROLLER/>, the <STACK/> will shrink rather than expand in that axis. |
In the below example STACK is used to create a custom header which is POSITIONED on top of a scrollable profile page prototype. STACK is also used to layer widgets over top of the profile picture.
