Usage

Fixed-size spacer

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

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

Flexible spacer

A flexible spacer fills the remaining space along its parent's main axis, pushing the surrounding content to opposite ends.

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

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