![]() The flexWrap property is set on containers and controls what happens when children overflow the size of the container along the main axis. Compared to space between using space around will result in space being distributed to the begining of the first lines and end of the last line. Space-around Evenly space wrapped lines across the container's main axis, distributing remaining space around the lines. Space-between Evenly space wrapped lines across the container's main axis, distributing remaining space between the lines. Stretch wrapped lines to match the height of the container's cross axis.Ĭenter Align wrapped lines in the center of the container's cross axis. ![]() This only has effect when items are wrapped to multiple lines using flexWrap.įlex-start ( default value) Align wrapped lines to the start of the container's cross axis.įlex-end Align wrapped lines to the end of the container's cross axis. alignSelf overrides any option set by the parent with alignItems.ĪlignContent defines the distribution of lines along the cross-axis. The spacing between each pair of adjacent items, the main-start edge and the first item, and the main-end edge and the last item, are all exactly the same.ĪlignSelf has the same options and effect as alignItems but instead of affecting the children within a container, you can apply this property to a single child to change its alignment within its parent. Space-evenly Evenly distributed within the alignment container along the main axis. Compared to space-between using space-around will result in space being distributed to the beginning of the first child and end of the last child. Space-around Evenly space of children across the container's main axis, distributing remaining space around the children. Space-between Evenly space of children across the container's main axis, distributing remaining space between the children. ![]() For example, you can use this property to center a child horizontally within a container with flexDirection set to row or vertically within a container with flexDirection set to column.įlex-start( default value) Align children of a container to the start of the container's main axis.įlex-end Align children of a container to the end of the container's main axis.Ĭenter Align children of a container in the center of the container's main axis. Justif圜ontent describes how to align children within the main axis of their container. Margin and padding applied the start of an element are applied on the right side. RTL Text and children are laid out from right to left. Margin and padding applied the start of an element are applied on the left side. LTR ( default value) Text and children are laid out from left to right. In this mode start refers to left and end refers to right. By default React Native lays out with LTR layout direction. Layout direction also affects what edge start and end refer to. Layout direction specifies the direction in which children and text in a hierarchy should be laid out. If wrapping is enabled then the next line will start to the left first item on the bottom of the container. ![]() If wrapping is enabled then the next line will start under the first item on the right of the container.Ĭolumn-reverse Align children from bottom to top. Row-reverse Align children from right to left. If wrapping is enabled then the next line will start to the left first item on the top of the container. If wrapping is enabled then the next line will start under the first item on the left of the container.Ĭolumn ( default value) Align children from top to bottom. The cross axis is the axis perpendicular to the main axis, or the axis which the wrapping lines are laid out in. This is also referred to as the main axis. 1+2+3 = 6 which means that the red view will get 1/6 of the space, the yellow 2/6 of the space and the green 3/6 of the space.įlexDirection controls the direction in which the children of a node are laid out. The red view uses flex: 1, the yellow view uses flex: 2 and the green view uses flex: 3. In the following example the red, yellow and the green views are all children in the container view that has flex: 1 set. Space will be divided according to each element's flex property. Flex įlex will define how your items are going to “fill” over the available space along your main axis. The defaults are different, with flexDirection defaulting to column instead of row, and the flex parameter only supporting a single number. You will normally use a combination of flexDirection, alignItems, and justif圜ontent to achieve the right layout.įlexbox works the same way in React Native as it does in CSS on the web, with a few exceptions. Flexbox is designed to provide a consistent layout on different screen sizes. A component can specify the layout of its children using the flexbox algorithm.
