Composable Function
Box
Common
```kotlin
@Composable
inline fun Box(
modifier: Modifier = Modifier,
contentAlignment: Alignment = Alignment.TopStart,
propagateMinConstraints: Boolean = false,
content: @Composable BoxScope.() -> Unit,
)
```
A layout composable with `content`. The `Box` 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 `Box` according to the `contentAlignment`. For individually specifying the
alignments of the children layouts, use the `BoxScope.align` modifier. By default, the content
will be measured without the `Box`'s incoming min constraints, unless `propagateMinConstraints`
is `true`. As an example, setting `propagateMinConstraints` to `true` can be useful when the
`Box` has content on which modifiers cannot be specified directly and setting a min size on the
content of the `Box` is needed. If `propagateMinConstraints` is set to `true`, the min size set
on the `Box` will also be applied to the content, whereas otherwise the min size will only apply
to the `Box`. When the content has more than one layout child the layout children will be stacked
one on top of the other (positioned as explained above) in the composition order.
