SpatialBox
Android
```kotlin
@Composable
@SubspaceComposable
public inline fun SpatialBox(
modifier: SubspaceModifier = SubspaceModifier,
alignment: SpatialAlignment = SpatialAlignment.Center,
propagateMinConstraints: Boolean = false,
crossinline content: @Composable @SubspaceComposable SpatialBoxScope.() -> Unit,
)
```
A layout composable that sizes itself to fit its content, subject to incoming constraints.
A layout composable with `content`. The [SpatialBox](/jetpack-compose/androidx.xr.compose/compose/composable-functions/SpatialBox) will size itself to fit the content, subject
to the incoming constraints. When children are smaller than the parent, by default they will be
positioned inside the [SpatialBox](/jetpack-compose/androidx.xr.compose/compose/composable-functions/SpatialBox) according to the [alignment](/jetpack-compose/androidx.compose.ui/ui/interfaces/Alignment). For individually specifying the
alignments of the children layouts, use the [SpatialBoxScope.align](/jetpack-compose/androidx.xr.compose/compose/interfaces/SpatialBoxScope) modifier. By default, the
content will be measured without the [SpatialBox](/jetpack-compose/androidx.xr.compose/compose/composable-functions/SpatialBox)'s incoming min constraints. If
`propagateMinConstraints` is set to `true`, the min size set on the [SpatialBox](/jetpack-compose/androidx.xr.compose/compose/composable-functions/SpatialBox) will also be
applied to the content.
Note: If the content has multiple children, they might overlap depending on their positioning.
