Struct BottomSheetView 

pub struct BottomSheetView<State: 'static> { /* private fields */ }

A declarative modal M3 bottom sheet wrapping a single content child. See the module docs.

Implementations

impl<State: 'static> BottomSheetView<State>

pub fn on_dismiss<F: Fn(&mut State) + 'static>(self, on_dismiss: F) -> Self

Set the dismiss callback — invoked with &mut State on a scrim tap or a handle drag release decided closed. show_bottom_sheet wires this to controller.pop() automatically.

pub fn dismissable(self, dismissable: bool) -> Self

Whether this sheet can be dismissed by the user at all — the scrim tap, the handle drag, Escape, and an Android back press (default true; see the module docs). false disables all four; only an explicit close control the app wires through its own content still dismisses it.

pub fn dismiss_handle(self, dismiss: ModalDismiss) -> Self

Install the app-triggered staged-dismiss handle: the sheet’s own content can then close it through the very spring exit the scrim tap, the handle drag, Escape, and an Android back press all take — instead of popping the navigator directly, which would drop the page out from under the sheet mid-slide. Reuses crate::overlay::modal::ModalDismiss — the same handle type crate::side_sheet::SideSheetView::dismiss_handle installs — so an app mixing sheet families never juggles two handle types. See the module docs’ app-initiated dismiss section.

Mint the handle outside show_bottom_sheet’s page builder and clone it in — the builder re-runs on every navigator rebuild.

let dismiss = ModalDismiss::new();
let select = dismiss.clone();
show_bottom_sheet(
    &nav,
    move || {
        bottom_sheet(menu_panel(rows(), move |state: &mut State, sel| {
            on_select(state, sel);
            select.dismiss();
        }))
        .dismiss_handle(dismiss.clone())
    },
    |state: &mut State, result: PopResult| { /* ... */ },
);

Trait Implementations

impl<State: 'static> View<State> for BottomSheetView<State>

type Element = BottomSheetWidget

The retained widget this view produces.

fn build(&self, ctx: &mut BuildCtx<'_>) -> BottomSheetWidget

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut BottomSheetWidget, ctx: &mut BuildCtx<'_>, ) -> ChangeFlags

fn teardown(&self, element: &mut BottomSheetWidget, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)
