FlashSaleScreen.displayName = "FlashSaleScreen";
Recreate the "Flash Sale" screen in React Native using LumioUI.
Goal: Flash sale grid: live countdown, discount badges, claimed-stock bars, cart additions Match the reference implementation's layout, behavior, and motion exactly — this is a production screen, not a mockup.
## Setup
Fastest path — install the screen plus its component deps:
```bash
npx lumioui add ecommerce-flash-sale
```
Or pull just the components: `npx lumioui add badge countdown icon image progress text`
Native packages:
- @lumioui/ui@latest
- @lumioui/core@latest
- react-native-safe-area-context@*
- react-native-reanimated@*
- react-native-svg@*
- nativewind@*
Stack assumptions: Expo SDK 54 / RN 0.81, Reanimated 4, NativeWind v4, TypeScript strict, Expo Go compatible.
## Components — how, where, when
### `badge` — Compact status pill with variants, icons and pulse option.
- imported but not rendered directly — likely used through a sibling or as a utility
### `countdown` — Live countdown with per-digit tick animation, compact and labeled-block layouts, completion haptic.
- `<Countdown>` ×1
### `icon` — Lucide icon set mapped to theme colors and sizes.
- `<Icon>` ×4
### `image` — Cached image with placeholder, fallback and aspect handling.
- `<Image>` ×1
### `progress` — Animated fill bar with indeterminate sweep mode.
- `<Progress>` ×1
### `text` — Themed type scale from caption to display.
- `<Text>` ×13
## Conventions (non-negotiable)
- Styling via NativeWind `className` with semantic tokens only: `bg-background`, `text-foreground`, `bg-card`, `text-card-foreground`, `bg-secondary`, `bg-muted`, `text-muted-foreground`, `bg-accent`, `bg-destructive`, `border-border`. Hard-coded colors only inside media overlays (`text-white`, `bg-black/N`).
- Motion via the token presets from `@lumioui/core` (`spring.press`, `spring.surface`, `spring.glide`, `timing.fast`, `timing.slow`, …) — no bespoke spring configs or durations.
- Gate transform motion behind `useReducedMotion()`; keep opacity/color feedback, drop travel and overshoot.
- Haptics via `useHaptic()`: `light` on press, `selection` on toggle/select, `warning` on invalid input. Never import expo-haptics directly.
- Press feedback via `usePressAnimation()` (~0.97 scale), not `activeOpacity` tricks.
- a11y: `accessibilityRole` + `accessibilityLabel` on every control, touch targets ≥44pt.
- Entrance choreography: staggered `Mount` wrappers (delay 0/60/120…) so regions land in sequence instead of popping in at once.
- Wrap the screen in `SafeAreaView`; keep dark mode working via the semantic tokens.
## Deliverable
One file: `screens/ecommerce/flash-sale.tsx` exporting FlashSaleScreen. Preserve the props interface — the host app wires the callbacks (navigation, submit handlers) through them.
