Variants and examples

Default

PortalHostDefault.tsx
1import { Text } from 'react-native';2import { PortalHost } from 'reactnatively';34export function Preview() {5  return (6    <PortalHost style={{ padding: 16 }}>7      <Text>PortalHost content</Text>8    </PortalHost>9  );10}

Composed example

PortalHostComposed.tsx
1import { Text } from 'react-native';2import { PortalHost, Box } from 'reactnatively';34export function PortalHostComposed() {5  return (6    <Box padding="md">7      <PortalHost>8        <Text>PortalHost content</Text>9      </PortalHost>10    </Box>11  );12}

TypeScript IntelliSense

The component exports typed props, so editors can autocomplete prop names, union values, callbacks, and theme-aware style objects as you type.

PortalHost.types-example.tsx
1import type { ComponentProps } from 'react';2import { PortalHost } from 'reactnatively';34type PortalHostProps = ComponentProps<typeof PortalHost>;56const exampleProps: PortalHostProps = {7  style: undefined,8  testID: "reactnatively-example",9  accessibilityLabel: "Example control",10};1112export function TypedPortalHost() {13  return <PortalHost {...exampleProps} />;14}

Theme support

PortalHost participates in the Reactnatively theme system through semantic colors, spacing, radii, typography, motion, and glass tokens where those props apply. Wrap your app in ReactnativelyProvider or ThemeProvider to keep light mode, dark mode, density, and custom tokens consistent.

Accessibility

Use accessible labels, hints, roles, and focus behavior when PortalHostis interactive. Reactnatively components are designed for React Native apps that need screen-reader support, reduced-motion handling, and consistent touch targets.

Expo compatibility

PortalHost can be used in Expo apps with TypeScript. Glass and blur behavior depends on platform capability, so production interfaces should keep text contrast and fallback tinting readable when native blur is unavailable.
