# Avatar

A round image for a person or entity, with initials or an icon as a fallback.

Avatar 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 { Avatar, AvatarFallback, AvatarImage } from "@/components/ui/avatar"

      <AvatarFallback>
        <Text>AL</Text>
      </AvatarFallback>
    </Avatar>

}
```

`Avatar` is a round `View` that holds an `AvatarImage` and an `AvatarFallback`. The image stays hidden until it loads, and the fallback is shown while it loads or if it fails. Four sizes are available: `sm`, `default`, `lg` and `xl`; the fallback text, icons and badge scale with the size.

`AvatarBadge` adds a small status dot in the bottom-end corner, and `AvatarGroup` overlaps several avatars with an outline between them, with `AvatarGroupCount` for the remaining number.

## Installation

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

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

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

The CLI also adds what it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text).

### Manual

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install cn
```

2. Add the pieces it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text), and the primitives `components/primitives/avatar.tsx`, `components/primitives/use-render.tsx`.

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

3. Update the import paths to match your project.

**SwiftUI**

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:

import androidx.compose.ui.unit.dp

val LocalContentStyle = compositionLocalOf { TextStyle.Default }

val LocalContentColor = compositionLocalOf { Color.Unspecified }

val LocalIconSize = compositionLocalOf { 20.dp }
```

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

## Usage

```tsx
import { Avatar, AvatarImage, AvatarFallback, AvatarBadge, AvatarGroup, AvatarGroupCount } from "@/components/ui/avatar"
```

```tsx
<Avatar>
  <AvatarImage
    alt="Ada Lovelace"
    source={{ uri: "https://i.pravatar.cc/150?img=5" }}
  />
  <AvatarFallback>
    <Text>AL</Text>
  </AvatarFallback>
</Avatar>
```

Give `AvatarImage` a `source` and an `alt`. Put initials or an `Icon` in `AvatarFallback`; plain strings are wrapped in `Text`. Use `delay` on the fallback to avoid a flash on fast connections, and `onLoadingStatusChange` on the image to react to loading.

Set `size` on each `Avatar`, and pass the same `size` to `AvatarGroupCount`. On the `sm` size, the badge hides its children and shows a plain dot.

## Examples

### Fallback

Initials shown when there is no image.

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

```tsx
import { Avatar, AvatarFallback } from "@/components/ui/avatar"
import { Text } from "@/components/ui/text"

export function AvatarFallbackExample() {
  return (
    <Avatar accessibilityLabel="Alan Turing">
      <AvatarFallback>
        <Text>AT</Text>
      </AvatarFallback>
    </Avatar>
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct AvatarFallbackExample: View {
  var body: some View {
    Avatar {
      AvatarFallback("AT")
    }
    .accessibilityLabel(Text("Alan Turing"))
  }
}
```

```kotlin
import androidx.compose.foundation.layout.Row

import androidx.compose.ui.Modifier
import androidx.compose.ui.semantics.contentDescription
import androidx.compose.ui.semantics.semantics

    Row {
        Avatar(
            modifier = Modifier.semantics { contentDescription = "Alan Turing" },
            fallback = { AvatarFallback("AT") },
        )
    }
}
```

### Sizes

The `sm`, `default`, `lg` and `xl` sizes.

## API Reference

### Avatar

Round container that sets the size.

### AvatarImage

Image that appears once it has loaded.

### AvatarFallback

Initials or icon shown while the image is missing.

### AvatarBadge

Status dot in the bottom-end corner.

### AvatarGroup

Row that overlaps its avatars.

### AvatarGroupCount

Round counter for the remaining items in a group.

## Accessibility

- `AvatarImage` uses `alt` as its `accessibilityLabel`.
- The image is hidden from screen readers until it has loaded.
- The badge has no label; describe the status in nearby text if it matters.

## Notes

- Uses `bg-label-secondary`, `bg-accent`, `bg-surface-secondary` and `border-surface` tokens; the fallback is softer in dark mode.
- Light and dark follow the system appearance.
