Layout
ZStack
Layer children on top of each other.
ZStack layers its children at the same position. Use it for overlays,
badges, image captions, or anywhere you need two views painted on top of one
another.
The default alignment is AlignCenter. Override it with .Align(...):
Every child is sized to the ZStack's bounds unless it has its own frame or padding. Later children render on top of earlier children.
Supported alignments: AlignTopLeading, AlignTop, AlignTopTrailing,
AlignLeading, AlignCenter, AlignTrailing, AlignBottomLeading,
AlignBottom, AlignBottomTrailing.
