Android
```kotlin public object Exact : SizeMode ``` The [GlanceAppWidget](/jetpack-compose/androidx.glance/glance-appwidget/classes/GlanceAppWidget) provides a UI for each size the App Widget may be displayed at. The list of sizes is provided by the options bundle (see `android.appwidget.AppWidgetManager.getAppWidgetOptions`). The composable will be run concurrently for each size. In each sub-composition, the [LocalSize](/jetpack-compose/androidx.glance/glance/properties/LocalSize) will be the one for which the UI is generated. See the note in [SizeMode](/jetpack-compose/androidx.glance/glance-appwidget/interfaces/SizeMode) for more info.
