Backend: Rewrote EventListAPI to query per-type with DB-level LIMIT
instead of loading all 734 events into memory. Added slim serializer
(32KB vs 154KB). Added DB indexes on event_type_id and pincode.
Frontend: Category chips now filter locally from _allEvents (instant,
no API call). Top Events and category sections always show all types
regardless of selected category. Added TTL caching for event types
(30min) and events (5min). Reduced API timeout from 30s to 10s.
Added memCacheHeight to all CachedNetworkImage widgets. Batched
setState calls from 5 to 2 during startup. Cached _eventDates getter.
Switched baseUrl to em.eventifyplus.com (Django via Nginx+SSL).
Added initialEvent param to LearnMoreScreen for instant detail views.
Resolved relative media URLs for category icons.

LearnMoreScreen now accepts an optional initialEvent parameter so it
can render immediately from already-loaded data instead of re-fetching
from the event-details API. This fixes the guest-mode flow where the
unauthenticated API call was failing. Also changed getEventDetails to
requiresAuth: true so logged-in users send their token when the API
path is used.

The guest button was nearly invisible (grey text, fontSize 13 on dark
background). Now uses white70, fontSize 15, TextButton with proper
tap padding. Also guards wishlist toggle on event detail page.

Three root causes of the perceived scroll/animation lag:
1. profile_screen.dart — AnimationController listener called setState() on
every animation frame (60fps × 2s = 120 full-tree rebuilds). The entire
ProfileScreen with its nested lists and images was rebuilding 60 times per
second just to update two small widgets (EXP bar + stat counters).
Fix: remove setState() from listeners entirely; wrap only the EXP bar
(LayoutBuilder) and stat row (IntrinsicHeight) in AnimatedBuilder so
only those two leaf widgets re-render per frame.
2. learn_more_screen.dart — PageView.onPageChanged called setState() on
every swipe, rebuilding the full event detail screen (blurred bg image,
map, about section, etc.) just to update the 6px dot indicators.
Fix: int _currentPage → ValueNotifier<int> _pageNotifier; wrap only the
dot row and the blurred background image in ValueListenableBuilder.
3. search_screen.dart — BackdropFilter(ImageFilter.blur) without a
RepaintBoundary forces Flutter to read every pixel behind the blur widget
and composite it every frame. When the user scrolls the underlying list,
the blur repaints continuously causing frame drops.
Fix: wrap BackdropFilter in RepaintBoundary to isolate its repaint layer.
Critical — Image.network → CachedNetworkImage:
- home_screen.dart: hero/carousel banner image now cached with placeholder
- profile_screen.dart: avatar and event list tile images now cached
- calendar_screen.dart: event card images now cached with placeholder
High:
- profile_screen.dart: TextEditingControllers in dialogs now properly
disposed via .then() and after await to prevent memory leaks
Medium:
- search_screen.dart: shrinkWrap:true → ConstrainedBox(maxHeight:320) +
ClampingScrollPhysics for smooth search result scrolling
- learn_more_screen.dart: MediaQuery.of(context) cached once per method
instead of being called multiple times on every frame
- Improved event detail page with carousel, map, and layout fixes
- Updated login screen with video background and glassmorphism
- API client development mode with mock responses
- Theme manager and main app updates
