Box

A theme-aware replacement for View with shorthand props for padding, margin, gap, alignment, and background color. Spacing values can be theme tokens (xs, sm, md, lg, xl) or raw numbers.

Usage

  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16 }}>
          <Box p="md" bg="#f5f5f5">
            <Typography variant="bodyMedium">Padded content</Typography>
          </Box>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>

import { Box, Typography } from '@onlynative/components'
import { ThemeProvider } from '@onlynative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center' }}>
          <Box p={20} mx={12} bg="#e0e0e0">
            <Typography>20dp padding, 12dp horizontal margin</Typography>
          </Box>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

Padding & Margin

Open on Snack ↗

import { Box, Typography } from '@onlynative/components'
import { ThemeProvider } from '@onlynative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, padding: 16, gap: 12 }}>
          <Box p="md" m="sm" bg="#fce4ec">
            <Typography>p="md" m="sm"</Typography>
          </Box>
          <Box px="lg" py="sm" bg="#e8f5e9">
            <Typography>px="lg" py="sm"</Typography>
          </Box>
          <Box pt="sm" pb="md" ps="lg" pe="xl" bg="#e3f2fd">
            <Typography>pt sm, pb md, ps lg, pe xl (RTL-aware)</Typography>
          </Box>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

ps and pe map to paddingStart / paddingEnd, so they flip automatically in RTL layouts. The same applies to ms / me.

Gap

Open on Snack ↗

import { Box, Button } from '@onlynative/components'
import { ThemeProvider } from '@onlynative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16 }}>
          <Box gap="sm">
            <Button variant="filled" onPress={() => {}}>First</Button>
            <Button variant="outlined" onPress={() => {}}>Second</Button>
          </Box>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

rowGap and columnGap are also available for finer control.
