In Material Design, a scaffold is a fundamental structure that provides a standardized platform for complex user interfaces. It holds together different parts of the UI, such as app bars and floating action buttons, giving apps a coherent look and feel.

## Results

![An implementation of scaffold that contains simple top and bottom app bars, as well as a floating action button that iterates a counter. The inner content of the scaffold is simple text that explains the component.](https://developer.android.com/static/develop/ui/compose/images/components/scaffold.png)**Figure 1.**An implementation of scaffold.

## Version compatibility

This implementation requires that your project minSDK be set to API level 21 or higher.

### Dependencies

### Kotlin

<br />

```kotlin
  implementation(platform("androidx.compose:compose-bom:2025.10.01"))
  
```

<br />

### Groovy

<br />

```groovy
  implementation platform('androidx.compose:compose-bom:2025.10.01')
  
```

<br />

## Create a scaffold

The following example provides a full example of how you might implement[`Scaffold`](https://developer.android.com/reference/kotlin/androidx/compose/material/package-summary#Scaffold(androidx.compose.foundation.layout.WindowInsets,androidx.compose.ui.Modifier,androidx.compose.material.ScaffoldState,kotlin.Function0,kotlin.Function0,kotlin.Function1,kotlin.Function0,androidx.compose.material.FabPosition,kotlin.Boolean,kotlin.Function1,kotlin.Boolean,androidx.compose.ui.graphics.Shape,androidx.compose.ui.unit.Dp,androidx.compose.ui.graphics.Color,androidx.compose.ui.graphics.Color,androidx.compose.ui.graphics.Color,androidx.compose.ui.graphics.Color,androidx.compose.ui.graphics.Color,kotlin.Function1)). It contains a top app bar, bottom app bar, and a floating action button that interacts with`Scaffold`'s internal state.

```kotlin
@Composable
fun ScaffoldExample() {
    var presses by remember { mutableIntStateOf(0) }

    Scaffold(
        topBar = {
            TopAppBar(
                colors = topAppBarColors(
                    containerColor = MaterialTheme.colorScheme.primaryContainer,
                    titleContentColor = MaterialTheme.colorScheme.primary,
                ),
                title = {
                    Text("Top app bar")
                }
            )
        },
        bottomBar = {
            BottomAppBar(
                containerColor = MaterialTheme.colorScheme.primaryContainer,
                contentColor = MaterialTheme.colorScheme.primary,
            ) {
                Text(
                    modifier = Modifier
                        .fillMaxWidth(),
                    textAlign = TextAlign.Center,
                    text = "Bottom app bar",
                )
            }
        },
        floatingActionButton = {
            FloatingActionButton(onClick = { presses++ }) {
                Icon(Icons.Default.Add, contentDescription = "Add")
            }
        }
    ) { innerPadding ->
        Column(
            modifier = Modifier
                .padding(innerPadding),
            verticalArrangement = Arrangement.spacedBy(16.dp),
        ) {
            Text(
                modifier = Modifier.padding(8.dp),
                text =
                """
                    This is an example of a scaffold. It uses the Scaffold composable's parameters to create a screen with a simple top app bar, bottom app bar, and floating action button.

                    It also contains some basic inner content, such as this text.

                    You have pressed the floating action button $presses times.
                """.trimIndent(),
            )
        }
    }
}

## Key points

The[`Scaffold`](https://developer.android.com/reference/kotlin/androidx/compose/material/ScaffoldState)composable provides a straightforward API you can use to quickly assemble your app's structure according to Material Design guidelines.`Scaffold`accepts several composables as parameters. Among these are the following:

- `topBar`: The app bar across the top of the screen.
- `bottomBar`: The app bar across the bottom of the screen.
- `floatingActionButton`: A button that hovers over the bottom-right corner of the screen that you can use to expose key actions.

For more detailed examples on how you can implement both top and bottom app bars, see the app bars page.

You can also pass`Scaffold`content as you would to other containers. It passes an`innerPadding`value to the`content`lambda that you can then use in child composables.
