From 03c13d21c6ea5561e8219cf8cd63368b86f3b339 Mon Sep 17 00:00:00 2001 From: Bryan Van Deusen Date: Wed, 13 May 2026 21:05:43 -0400 Subject: [PATCH] feat(flutter): home screen on per-item rendering (Slice C) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit End-to-end pilot of the per-item architecture. Home now reads from the new homeIndexProvider (drift-first over CachedHomeIndex with /api/home/index discovery + SWR), then each tile is a small ConsumerWidget watching its own albumTileProvider/artistTileProvider/ trackTileProvider. Tiles render a matched-dimension skeleton while their entity is still hydrating, and swap in the real card once drift emits the populated row. Track hydration is wired up — /api/tracks/:id already existed so the queue's case 'track' just calls api.getTrack(id) and persists. The visible behavior: * Cold visit: small /api/home/index round-trip (IDs only, ~10× smaller than /api/home), then sections appear shaped with skeleton tiles; each tile materializes as the hydration queue drains. No more "30s blank → everything pops in at once." * Warm visit: drift index emits instantly, drift entity rows emit instantly, no network. Page paints fully in the first frame. * Mid-state: scrolling through a partially-hydrated section sees real cards next to skeleton cards. Layout doesn't shift because skeletons match real-card dimensions exactly. CachedHomeSnapshot (and the legacy homeProvider) stay in place but unconsumed by Flutter — left in for now so revert is cheap if the new path needs reworking. Cleanup follow-up in a later slice. Old /api/home endpoint untouched, so the web client keeps working unchanged. --- flutter_client/lib/api/endpoints/library.dart | 19 ++ flutter_client/lib/cache/hydration_queue.dart | 12 +- flutter_client/lib/cache/tile_providers.dart | 14 +- flutter_client/lib/library/home_screen.dart | 263 +++++++++++------- .../lib/library/library_providers.dart | 90 ++++++ flutter_client/lib/models/home_index.dart | 41 +++ .../test/library/home_screen_test.dart | 62 ++--- 7 files changed, 345 insertions(+), 156 deletions(-) create mode 100644 flutter_client/lib/models/home_index.dart diff --git a/flutter_client/lib/api/endpoints/library.dart b/flutter_client/lib/api/endpoints/library.dart index 8fab0c23..6d38b154 100644 --- a/flutter_client/lib/api/endpoints/library.dart +++ b/flutter_client/lib/api/endpoints/library.dart @@ -3,6 +3,7 @@ import 'package:dio/dio.dart'; import '../../models/album.dart'; import '../../models/artist.dart'; import '../../models/home_data.dart'; +import '../../models/home_index.dart'; import '../../models/track.dart'; /// LibraryApi wraps the server's native /api/* library surface. @@ -27,6 +28,24 @@ class LibraryApi { return HomeData.fromJson(r.data ?? const {}); } + /// GET /api/home/index — per-item rendering variant.
