From 0c4e62d00e393a1af9276c04c91a5d7766014ce6 Mon Sep 17 00:00:00 2001 From: Sicherhaven Date: Fri, 20 Mar 2026 22:26:52 +0530 Subject: [PATCH] perf: add memCacheWidth/memCacheHeight to all thumbnail images MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All CachedNetworkImage instances in list/card contexts now decode at 2x rendered size instead of full resolution. A 3000x2000 event photo previously decoded to ~24MB in GPU memory even when shown at 96px — now decodes to <1MB. Affected screens (16 CachedNetworkImage instances total): - home_screen.dart: hero (800w), top card (300w), stacked (192w), horizontal (440x360), full-width (800x400), search (112x112), filter sheet (160x160), type icons (112x112) - home_desktop_screen.dart: mini (128x128), grid (600x280), horiz (600x296) - calendar_screen.dart: event card (400x300) - profile_screen.dart: avatar (size*2), event tile (120x120) learn_more_screen.dart intentionally unchanged — full-res for detail view. Estimated memory reduction: ~500MB → ~30MB for a typical home screen. --- .claude/launch.json | 12 ++++++++++++ lib/screens/calendar_screen.dart | 2 ++ lib/screens/home_desktop_screen.dart | 6 ++++++ lib/screens/home_screen.dart | 13 +++++++++++++ lib/screens/profile_screen.dart | 4 ++++ 5 files changed, 37 insertions(+) create mode 100644 .claude/launch.json diff --git a/.claude/launch.json b/.claude/launch.json new file mode 100644 index 0000000..e69f128 --- /dev/null +++ b/.claude/launch.json @@ -0,0 +1,12 @@ +{ + "version": "0.0.1", + "autoPort": true, + "configurations": [ + { + "name": "flutter-web", + "runtimeExecutable": "bash", + "runtimeArgs": ["/Users/bshtechnologies/Documents/Eventify-frontend/run_web.sh"], + "port": 8080 + } + ] +} diff --git a/lib/screens/calendar_screen.dart b/lib/screens/calendar_screen.dart index 44bded0..747a537 100644 --- a/lib/screens/calendar_screen.dart +++ b/lib/screens/calendar_screen.dart @@ -515,6 +515,8 @@ class _CalendarScreenState extends State { child: imgUrl != null ?
