The Flow.layout type.
Values
Horizontal
Children are aligned horizontally from left to right (or right to left when Flow.reverse is enabled).
If Flow.multiline is enabled - children can overflow to the next row if there is not enough space available within the Flow size constraints.
Flow.lineHeight can be used to set a fixed row height when Flow.overflow is set to Limit or Hidden.
Objects with height that exceed the limitation will be aligned according to Flow.verticalAlign value vertically with null being treated as Bottom.
Vertical
Children are aligned vertically from top to bottom (or bottom to top when Flow.reverse is enabled).
If Flow.multiline is enabled - children can overflow to the next column if there is not enough space available within the Flow size constraints.
Flow.colWidth can be used to set a fixed column width when Flow.overflow is set to Limit or Hidden.
Objects with height that exceed the limitation will be aligned according to Flow.horizontalAlign value horizontally with null being treated as Left.
Stack
Children are aligned independently (Flow.reverse has no effect).
