Properties

nativeObject: any
direction: Flex.Direction

This property specifies where items will start to be positioned. If you set RTL(right to left) objects will be positioned by starting from right edge of the Flex. If you set LTR(left to right) objects will be positioned by starting from left edge of the Flex.

Example

import FlexLayout from '@smartface/native/ui/flexlayout';
var myFlexLayout = new FlexLayout({
flexGrow : 1
direction: Flex.Direction.RTL
});

Property

= UI.Flex.Direction.INHERIT]

Since

0.1

flexDirection: Flex.FlexDirection

This property specifies how children will be placed(horizontally or vertical) in Flex. It defines the main axis. It works like flex-direction on CSS.
