## [1.6.1] - 2026-04-04

Phase 4 — animation polish and final feature gaps. Flutter app reaches full feature parity with Consumer Web App v1.4.9.

### Added
- **BouncingLoader widget** (`lib/widgets/bouncing_loader.dart`): 3-dot bouncing animation with staggered 200 ms delays using `Curves.bounceOut`. Replaces `CircularProgressIndicator` in home, contribute, and review screens. Accepts `color`, `dotSize`, and `spacing` parameters.
- **DiceBear Notionists avatars on review cards** (REV-001): `CachedNetworkImage` fetches `api.dicebear.com/9.x/notionists/svg?seed={username}`. Falls back to coloured initial letter `CircleAvatar` on error or while loading.
- **Server-side event search** (HOME-007): Search modal now sends `q` param to `EventsByPincodeView`; client-side filter stays for instant `onChanged` feedback while server results load on submit. Cache is bypassed for search queries. Django backend updated with `Q(title__icontains=q) | Q(description__icontains=q)` OR filter.
- **`flutter_staggered_animations: ^1.1.1`** added to pubspec.

### Changed
- **Review list stagger animation** (REV-003): `AnimationLimiter` + `AnimationConfiguration.toStaggeredList` wraps review cards with 375 ms slide-up + fade-in per item.
- **Review submit success spring animation** (REV-004): Checkmark icon now animates with `ScaleTransition` driven by `Curves.elasticOut` (600 ms) instead of a static icon swap.
- **Hero transitions on event cards** (UX-005): `Hero(tag: 'event-hero-{id}')` wraps event images in home screen and matching destination in learn more screen — enabling shared-element transitions.
- **FadeTransition on learn more screen** (UX-005): Screen body fades in with `Curves.easeIn` (350 ms) after event data loads.
- **AnimatedList stagger on leaderboard** (UX-005): `SliverList` entries animate with `AnimationConfiguration.staggeredList` — 375 ms slide-up + fade-in per row.
