+ * <a href="https://m3.material.io/components/bottom-sheets/overview" class="external" target="_blank">Material Design modal bottom sheet</a>.
+ *
+ * Modal bottom sheets are used as an alternative to inline menus or simple dialogs on mobile,
+ * especially when offering a long list of action items, or when items require longer descriptions
+ * and icons. Like dialogs, modal bottom sheets appear in front of app content, disabling all other
+ * app functionality when they appear, and remaining on screen until confirmed, dismissed, or a
+ * required action has been taken.
+ *
+ * ![Bottom sheet image](https://developer.android.com/images/reference/androidx/compose/material3/bottom_sheet.png)
+ *
+ * A simple example of a modal bottom sheet looks like this:
+ *
+ * @sample androidx.compose.material3.samples.ModalBottomSheetSample
+ *
+ * @param onDismissRequest Executes when the user clicks outside of the bottom sheet, after sheet
+ * animates to [Hidden].
+ * @param modifier Optional [Modifier] for the bottom sheet.
+ * @param sheetState The state of the bottom sheet.
+ * @param shape The shape of the bottom sheet.
+ * @param containerColor The color used for the background of this bottom sheet
+ * @param contentColor The preferred color for content inside this bottom sheet. Defaults to either
+ * the matching content color for [containerColor], or to the current [LocalContentColor] if
+ * [containerColor] is not a color from the theme.
+ * @param tonalElevation The tonal elevation of this bottom sheet.
+ * @param scrimColor Color of the scrim that obscures content when the bottom sheet is open.
+ * @param dragHandle Optional visual marker to swipe the bottom sheet.
+ * @param windowInsets window insets to be passed to the bottom sheet window via [PaddingValues]
+ * params.
+ * @param content The content to be displayed inside the bottom sheet.
