export default function ColumnExample() {
  return (
    <Host matchContents>
      <Column spacing={8}>

        <Text>Second</Text>
        <Text>Third</Text>
      </Column>
    </Host>
  );
}

Alignment

Use alignment to position children along the cross (horizontal) axis.

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

export default function ColumnAlignmentExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Column spacing={8} alignment="center">
