Toast | RiseUI

Surface snackbar stack aligned with HeroUI v3 toast region — shadow card, semantic title, muted description, indicator, action, and close.

Wrap your app with RiseToast.wrap in MaterialApp.builder so overlays paint above routes. Defaults mirror HeroUI constants.ts (DEFAULT_TOAST_TIMEOUT 4000 ms, DEFAULT_GAP 12, DEFAULT_MAX_VISIBLE_TOAST 3, DEFAULT_TOAST_WIDTH 460).

HeroUI story parity

Default / Accent (`toast.info`) / Success / Warning / Danger with description, indicator, and action — mirrors Storybook `Template`.

RiseToast.show(
  context,
  variant: RiseToastVariant.default_,
  title: 'You have been invited to join a team',
  description: 'Bob sent you an invitation to join HeroUI team',
  indicator: Icon(Icons.people_outline, size: 16),
  action: RiseToastAction(
    label: 'Dismiss',
    onPressed: RiseToast.clear,
  ),
);

Placements

`RiseToastPlacement`: top · top-start · top-end · bottom · bottom-start · bottom-end (toast-region placements in toast.css).

RiseToast.show(
  context,
  title: 'Placement: Top start',
  placement: RiseToastPlacement.topStart,
);

Loading

`isLoading: true` shows [RiseSpinner] in the indicator slot; `duration: Duration.zero` keeps the toast until dismissed.

RiseToast.show(
  context,
  title: 'Saving…',
  showDefaultIndicator: false,
  isLoading: true,
  duration: Duration.zero,
);
