更新日志

在 Row 或 Column 内部，在兄弟组件之间生成空白空间的布局间隔器。使用 size 创建固定间隙，或使用 flexible 填充剩余的主轴空间。

安装

Terminal

- npx expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

用法

固定大小间隔

FixedSpacerExample.tsx

import { Host, Column, Text, Spacer } from '@expo/ui';

export default function FixedSpacerExample() {
  return (
    <Host matchContents>
      <Column>
        <Text>顶部</Text>
        <Spacer size={32} />
        <Text>底部</Text>
      </Column>
    </Host>
  );
}

弹性间隔

弹性间隔会沿其父元素的主轴填充剩余空间，将周围内容推到两端。

FlexibleSpacerExample.tsx

import { Host, Row, Text, Spacer } from '@expo/ui';

export default function FlexibleSpacerExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Row>
        <Text>前导</Text>
        <Spacer flexible />
        <Text>尾随</Text>
      </Row>
    </Host>
  );
}

API

import { Spacer } from '@expo/ui';
