Usage

Basic surface

BasicSurfaceExample.tsx

import { Host, Surface, Text } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function BasicSurfaceExample() {
  return (
    <Host matchContents>
      <Surface modifiers={[paddingAll(16)]}>
        <Text>Content on a surface</Text>
      </Surface>
    </Host>
  );
}

Surface with elevation

Use tonalElevation and shadowElevation to control the visual depth of the surface.

SurfaceElevationExample.tsx

import { Host, Surface, Column, Text } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function SurfaceElevationExample() {
  return (
    <Host matchContents>
      <Column modifiers={[paddingAll(16)]}>
        <Surface tonalElevation={1} shadowElevation={2} modifiers={[paddingAll(16)]}>
          <Text>Low elevation</Text>
        </Surface>
        <Surface tonalElevation={4} shadowElevation={8} modifiers={[paddingAll(16)]}>
          <Text>High elevation</Text>
        </Surface>
      </Column>
    </Host>
  );
}

Surface with custom colors

Use the color and contentColor props to override the default Material theme colors.

SurfaceCustomColorsExample.tsx

import { Host, Surface, Text } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function SurfaceCustomColorsExample() {
  return (
    <Host matchContents>
      <Surface
        color="#1E3A5F"
        contentColor="#FFFFFF"
        tonalElevation={2}
        modifiers={[paddingAll(16)]}>
        <Text color="#FFFFFF">Custom colored surface</Text>
      </Surface>
    </Host>
  );
}

Surface with shape and border

Use the shape prop to clip content and border to draw a stroke around the surface.

SurfaceShapeBorderExample.tsx

import { Host, Surface, Shape, Text } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function SurfaceShapeBorderExample() {
  return (
    <Host matchContents>
      <Surface
        shape={Shape.RoundedCorner({
          cornerRadii: { topStart: 16, topEnd: 16, bottomStart: 16, bottomEnd: 16 },
        })}
        border={{ width: 2, color: '#6200EE' }}
        modifiers={[paddingAll(16)]}>
        <Text>Rounded surface with border</Text>
      </Surface>
    </Host>
  );
}
