# Spacer

A layout spacer that produces empty space between siblings.
Android, iOS, Web, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

A layout spacer that produces empty space between siblings inside a [`Row`](/versions/v56.0.0/sdk/ui/universal/row) or [`Column`](/versions/v56.0.0/sdk/ui/universal/column). Use [`size`](/versions/v56.0.0/sdk/ui/universal/spacer#size) for a fixed gap, or [`flexible`](/versions/v56.0.0/sdk/ui/universal/spacer#flexible) to fill the remaining main-axis space.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Fixed-size spacer

```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.

```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>
  );
}
```
