FlexDirection enum
Defines the direction in which children are laid out in a flex container.
The flex direction determines the primary axis along which flex items are placed. It affects how items flow and wrap within the container. The direction can be horizontal (row-based) or vertical (column-based), and can be reversed to change the order of item placement.
Use this enum to control the main layout axis of a flex container. For example,
setting direction to FlexDirection.row will arrange children horizontally,
while FlexDirection.column arranges them vertically. Reverse directions
(rowReverse, columnReverse) place items in the opposite order along the axis.
Values
- row → const FlexDirection
-
Children are laid out horizontally from left to right. This is the default direction for most Western languages.
const FlexDirection(LayoutAxis.horizontal, false) - rowReverse → const FlexDirection
-
Children are laid out horizontally from right to left. Useful for right-to-left languages or when you want items in reverse order.
const FlexDirection(LayoutAxis.horizontal, true) - column → const FlexDirection
-
Children are laid out vertically from top to bottom. Commonly used for navigation menus or stacked content.
const FlexDirection(LayoutAxis.vertical, false) - columnReverse → const FlexDirection
-
Children are laid out vertically from bottom to top. Items are placed starting from the bottom of the container upwards.
const FlexDirection(LayoutAxis.vertical, true)
