The hero-era loading machinery survived the hero-flight revert: the
loading scaffold rendered the real cover, _RouteSettled deferred the
swap until the push transition ended, and SkeletonCrossfade faded
between the two. The loaded header decodes the cover under a different
mem-cache key (viewport-sized vs full-res), so opening an album from
the artist screen flashed the cover: shown, blanked, shown again.
Restore the pre-hero flow: shimmer skeleton while loading, hard cut to
AlbumScreen so the cover appears exactly once. Removes the now-unused
_AlbumLoadingScaffold and three imports that only existed for it.
The M4A, MP3, and APE scanners hand-copied AudioMetadata into the scan result
field-for-field, identical to the existing applyAudioMetadataToScan helper
(same Date-else-Year fallback). Route them through it. Ogg is left as-is (it
intentionally has no Year fallback) and FLAC uses the separate Metadata type.
The download- and metadata-provider priority pages were 99% identical. Extract
ProviderPriorityListPage taking the provider-list load/save callbacks and
labels; both pages become thin wrappers. (The metadata page's explicit
saveLabel was the same dialogSave the scaffold already defaults to.)
Delete the verbatim-duplicate LocalLibraryLookup class + provider, the unused
localLibrarySummaryProvider, notifier search()/getCount()/existsInLibrary
wrapper, and the now-orphaned LibraryDatabase.search(); the notifier's async
getById/findExisting lookups (the real ones) stay. Drop dead
download-history removeBySpotifyId/getDatabaseCount and the orphaned
history deleteBySpotifyId, and fold the byte-identical addToHistory/
adoptNativeHistoryItem into one _persistHistoryItem keeping distinct log text.
Delete dead extension_provider members (ensureSpotifyWebExtensionReady,
enabledExtensions, getExtension, resolveProviderDisplayName, URLHandler.matchesURL,
Extension.hasBrowseCategories) and collapse resolveEffectiveDownloadService/
MetadataProvider into one predicate-parameterized helper.
TrackState.searchArtists/searchAlbums/searchPlaylists were only ever written
empty (the metadata-search parse loops iterated const [] lists and customSearch
set []), so the home feed's separate artist/album/playlist result sections
never rendered. Drop the fields, the dead parse loops and _parseSearch* helpers,
the SearchArtist/Album/Playlist models, the sort caches/methods, and the
_Search* result widgets. The live tracks->buckets sections (_CollectionItemWidget
via artistItems/albumItems/playlistItems) and the search filter tabs are kept.
