/// BottomSheet is a View Model for this component
///
/// ## Fields:
///
/// - detent: The zero‑based index of the detent the sheet should open to.
/// - detents: Detents (discrete height states) the sheet can snap to.
/// - handle: Whether to display a drag handle and enable the top region of the sheet as a gesture
///     surface for dragging between detents.
/// - handle_label: The accessible label given to the drag handle.
/// - hideable: Whether the bottom sheet can hide when its swiped down.
/// - hide_friction: The friction coefficient to hide the sheet.
/// - modal: Whether the bottom sheet behaves as modal.
/// - open: Whether the bottom sheet is open.
/// - overshoot_limit: A fractional value, between 0 and 100, indicating the maximum visual overshoot allowed when dragging past the minimum or maximum size.
///
