FossToast class Overlays

See the toast documentation ↗ or try it live in the playground ↗.

One transient notification. Enqueue it with showFossToast or a FossToastController; the surface stays on the popover role for every variant, which tints only the leading glyph.

Customize globally by passing your own FossThemeData, or per instance through the widget's style object. There are no per-instance token props: to change color, radius, or spacing, change the theme.

See also FossToaster, the host that displays toasts, and FossAlert for a persistent inline message.

showFossToast(
  context,
  const FossToast(variant: FossToastVariant.success, title: Text('Saved')),
);
