# Screen

A full-screen container that pads for safe area insets and sets the status bar style.

Screen is an open-source mobile component from suiss/uim for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

```tsx
import { View } from "react-native"
import { Screen, ScreenContent } from "@/components/ui/screen"
import { Text } from "@/components/ui/text"

function Rows({ count = 4 }: { count?: number }) {
  return (
    <View className="overflow-hidden rounded-2xl bg-surface-secondary">
      {Array.from({ length: count }, (_, index) => `Row ${index + 1}`).map(
        (label, index) => (
          <View
            key={label}
            className={
              index > 0 ? "border-t border-separator px-4 py-3" : "px-4 py-3"
            }
          >
            <Text>{label}</Text>
          </View>
        )
      )}
    </View>
  )
}

export function ScreenExample() {
  return (
    <Screen className="-m-4">
      <ScreenContent>
        <Text variant="h2">Account</Text>
        <Text variant="muted">
          The screen pads every safe-area edge and sets the status bar style
          from the color scheme.
        </Text>
        <Rows />
      </ScreenContent>
    </Screen>
  )

```

```swift

      ScreenContent(scroll: false) {
        Text("Account").textVariant(.h2)

          .textVariant(.muted)
        ScreenRows()
      }
    }
  }
}

struct ScreenRows: View {
  var labels: [String] = (1...4).map { "Row \($0)" }
  var background: Color = .surfaceSecondary

  var body: some View {
    VStack(spacing: 0) {
      ForEach(Array(labels.enumerated()), id: \.offset) { index, label in
        Text(verbatim: label)
          .textVariant(.default)
          .frame(maxWidth: .infinity, alignment: .leading)
          .padding(.horizontal, 16)
          .padding(.vertical, 12)
          .overlay(alignment: .top) {

```

`Screen` is a `View` that fills the screen, paints the surface background and adds padding for the safe area insets on the edges you choose. It also renders a `StatusBar` with light or dark content to match the color scheme.

`ScreenContent` lays out the body with padding and gaps. With `scrollable`, it renders a `KeyboardScrollView` so content scrolls and stays above the keyboard.

## Installation

```bash title="Terminal"
npx @esuiss/uim@latest add screen
```

```bash title="Terminal"
npx @esuiss/uim@latest add screen --platform swift
```

```bash title="Terminal"
npx @esuiss/uim@latest add screen --platform kotlin
```

The CLI also adds what it builds on: [Keyboard Scroll View](/docs/components/keyboard-scroll-view).

### Manual

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install cn react-native-safe-area-context
```

2. Add the pieces it builds on: [Keyboard Scroll View](/docs/components/keyboard-scroll-view).

3. Copy the source into `components/ui/screen.tsx`:

type ScreenEdge = "top" | "right" | "bottom" | "left"

const ALL_EDGES: readonly ScreenEdge[] = ["top", "right", "bottom", "left"]

const ScreenContext = React.createContext<{
  edges: readonly ScreenEdge[]
} | null>(null)

function Screen({
  edges = ALL_EDGES,
  variant = "default",
  className,

        {...props}
      >
        <StatusBar
          barStyle={scheme === "dark" ? "light-content" : "dark-content"}

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

4. Add the files to your app target.

**Jetpack Compose**

1. Set `minSdk` to 24 or higher and add the dependencies:

```kotlin title="build.gradle.kts"
implementation(platform("androidx.compose:compose-bom:2026.09.00"))
implementation("androidx.compose.foundation:foundation")
implementation("androidx.compose.ui:ui")
```

2. Copy the theme files every view uses:

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

```tsx
import { Screen, ScreenContent } from "@/components/ui/screen"
```

```tsx
<Screen className="-m-4">
  <ScreenContent>
    <Text variant="h2">Account</Text>
    <Text variant="muted">
      The screen pads every safe-area edge and sets the status bar style
      from the color scheme.
    </Text>
    <Rows />
  </ScreenContent>
</Screen>
```

Wrap each screen in `Screen` and put the body in `ScreenContent`. Use `variant="secondary"` for grouped screens such as settings.

Pass `edges` to pad only some sides, for example `["top"]` when a tab bar or bottom bar handles the bottom inset. Set `scrollable` on `ScreenContent` for content taller than the screen or for forms.

The app must be wrapped in a `SafeAreaProvider` from `react-native-safe-area-context`. `ScreenContext` exposes the active `edges` to children.

## Examples

### Secondary

A screen with the `secondary` background.

![Preview](https://uim.suiss.app/previews/components-screen--secondary.light.webp)

```tsx
import { View } from "react-native"

## API Reference

### Screen

The root view that pads for safe area insets.

### ScreenContent

The padded body, optionally scrollable.

## Notes

- Uses the `bg-surface` and `bg-surface-secondary` tokens.
- The status bar uses `light-content` in dark mode and `dark-content` in light mode, following the system appearance.
- Requires `react-native-safe-area-context` and the Keyboard Scroll View component.
