Track options gain an Open on... entry listing every streaming platform
song.link resolves for the track, served by a new generic
GetTrackPlatformLinks with its own memory cache beside the availability
cache (same request budget). The sheet is data-driven from the platform
map so the app core stays service-agnostic. Completes the bridge
wrappers already landed in 901fa34d; also carries the en strings for
the duplicate review sheet landing next.
- SettingsGroup centers itself at 720dp via its incoming constraint
(not screen width, so groups inside clamped sheets are never
over-inset; unbounded-width contexts guarded); priority scaffold,
bespoke hero cards, and donate page get the same inset - all 18+
settings pages clamp from shared widgets
- queue list-mode, local/downloaded album track lists, favorite
artists, home recent-access, and extension detail sections adopt
wideListInset like the screens fixed earlier
- track metadata content clamped at 720dp, which also tames the
width-derived spectrogram height
- announcement dialog capped at 480dp wide; setup wizard and
tutorial content at 560dp with a 400dp action button
The full-bleed cover made the Hero flight from square list thumbnails
morph into a fullscreen rect and back. The header now blurs the cover
as a backdrop and shows a centered rounded square (album header layout),
so the flight stays square end to end.
- album/playlist/library-folder/track-metadata adopt
CollapsingHeaderScrollMixin; artist/library-folder adopt
SelectionModeMixin
- HeaderCircleButton and HeaderMetaRow replace per-screen copies
in album and playlist headers; dead _tallHeader flag removed
- SelectionBottomBar gains optional subtitle labels and backs the
playlist selection bar in queue tab
- single-track convert sheet now reuses BatchConvertSheet
(confirmLabelBuilder + sourceIsLossless params) instead of a
full inline copy
- provider priority page migrated to PrioritySettingsScaffold;
shared showDiscardChangesDialog and ReorderablePriorityItem
replace per-page copies
- home tab search rows unified into one _SearchResultRowItem;
_parseTrack copies rebuilt on Track.fromBackendMap with only
the load-bearing local overrides kept; loading/error scaffold
extracted
- PlayerArtwork widget shared by now-playing and mini player
- LocalOrNetworkCoverImage dispatches file vs network cover in
one place (playlist picker, queue nav, library folder)
The local/downloaded album screens had drifted copies of the album
header, selection bottom bar, disc chip, batch convert/ReplayGain trio,
and assorted small helpers. All now delegate to the shared widgets, with
the online album screen's design as the reference, and both album screens
run batch actions through the queue_tab engine via UnifiedLibraryItem
(strict-superset implementation covering both DB writebacks and SAF
paths). Also folds the remaining per-screen helper copies (cover URL,
error card, byte/clock formatting, readPositiveInt) into their shared
homes.
Intentional deltas: selection-bar strings follow queue_tab's l10n keys,
both providers reload after a conversion, and audio-analysis durations
round instead of floor.
Service ids ('deezer', 'tidal', 'qobuz', 'spotify', 'amazon', 'local')
were compared as raw string literals in every dispatch chain. Introduce
MusicServices constants and use them at the comparison/switch sites so
a typo becomes a compile error instead of a silently dead branch.
track_metadata_screen.dart was 5,470 lines, most of it one State class
mixing five surfaces. Move four cohesive method clusters into private
extensions on _TrackMetadataScreenState in new part files: header/info
cards, lyrics + save/re-enrich flows, audio conversion + CUE split, and
file actions. Same library, so private state access is unchanged;
setState goes through a _setState forwarder as in queue_tab. The screen
file is now 1,575 lines.
Use DraggableScrollableSheet for single and batch convert flows and open
convert sheets with isScrollControlled so long option lists remain usable
on smaller screens.
Let users choose FFmpeg dithering when reducing bit depth and SoXr or
SWR resampling when changing sample rate across single-track and batch
lossless conversion flows.
Capture lossless conversion labels before await boundaries in queue,
downloaded album, and track metadata flows to avoid BuildContext usage
across async gaps.
Expose an awaitable lyrics settings sync on SettingsNotifier and call it
before metadata re-enrich, lyrics autofill, and queue/local embed flows so
the backend uses the latest provider order and fetch options.
Pass localized lossless conversion labels through shared helpers and
replace hardcoded capped-lossless confirmation text in single-track and
batch convert flows across metadata, queue, and album screens.
- LosslessConversionQuality model with bit depth/sample rate caps,
applied only when they reduce source quality
- FFmpegService probes sample rate and appends codec-specific args
(-ar, -sample_fmt, -bits_per_raw_sample) for FLAC/ALAC/WAV/AIFF
- Batch + single-track convert sheets expose quality cap options
- Persist real converted bit depth/sample rate to history/library DB
- track_metadata: recognize and convert to WAV/AIFF targets
- convertedAudioQualityLabel reflects actual output quality
- PlaybackController with queue methods for albums/library/playlists
- Library tab play builds merged queue (downloaded + local together)
- Preview vs main player exclusivity
- Preview stops on bottom-nav tab switch
- Duration 0:00 fix, deleted track cleanup, Up Next sheet
- Animation utilities improvements
FFmpeg's MP4 muxer drops ISRC and label, so write them as iTunes freeform atoms natively after every M4A embed pass. The metadata screen now reads all edited fields from the file on load (file is the source of truth), fixing edited values reverting to stale cached values after reopening.
- app: clear displayFeatures so bottom sheets/dialogs center on large/foldable screens
- edit metadata sheet: card sections, modern label-above inputs, elegant collapsible headers, removed title icon
- convert + batch convert: modern card-based sheets; shared BatchConvertSheet widget
- queue: keep selection toolbar hidden until modal close animation finishes
- 24-bit and In Library badges now use primary dynamic color
- artist skeleton: remove duplicate name/listeners lines, keep cover placeholder
- files settings: own filename-format controller in a StatefulWidget to fix use-after-dispose crash
WAV/AIFF: library scan, quality probe, native tag read/write via embedded ID3 chunk (RIFF id3 / AIFF ID3), cover art, ReadFileMetadata, ExtractLyrics, and FLAC<->WAV/AIFF conversion (PCM, bit-depth preserved via ffprobe). Treat WAV/AIFF as lossless across all convert sheets (no bitrate picker, Lossless labels) via isLosslessConversionTarget. Native MIME maps for SAF. Redesign the track metadata three-dot menu to a settings-style grouped card with a single divider above Share.
LyricsPlus (KPOE): word-by-word synced lyrics with multi-server failover, converted to enhanced LRC. ReplayGain: standalone EBU R128 (re)scan writing REPLAYGAIN_TRACK_* tags via native writers or FFmpeg, with batch action in queue/album screens and SAF support.
- Re-enrich: reject candidates that don't match title/artist/album unless exact ISRC match
- Respect settings.embedLyrics instead of hardcoding true in re-enrich flows
- Skip lyrics resolution in NativeDownloadFinalizer when not needed
- Apple Music lyrics: use direct catalog API with token scraping instead of Paxsenix search
- Support ELRC/ELRCMultiPerson/Plain formats in Apple Music lyrics response
- Add confidence check in metadata auto-fill to prevent applying wrong metadata
- Add tests for stricter re-enrich matching logic
Audio Analysis:
- Add rescan capability by bumping cache version
- Display channel layout (stereo, 5.1, etc.) and bitrate
- Use astats filter for more accurate peak/RMS measurements
- Support more formats: mp4, ac3, eac3, mka, wv, ape, tta, aif
- Only report bit depth for codecs that store it (FLAC, ALAC, WAV)
- Validate cache for SAF content:// URIs
Conversion:
- Add AAC as conversion target format
- Recognize ALAC as lossless source
- Prevent accidental deletion when source and target URI match
- Store format and bitrate in database after conversion
Utilities:
- Add audio_conversion_utils.dart for centralized conversion logic
- Add isSameContentUri() helper for safe URI comparison
The HIGH-quality lossy format picker can now produce an AAC/M4A 320 kbps output alongside MP3 and Opus. FFmpegService.convertM4aToLossy/convertAudioFormat, the Dart queue pipeline, the Kotlin finalizer, and the library database format helper all route .m4a through a unified aac codec path and tag the resulting file with the M4A metadata writer. The Lossy Format setting gains a new option, and the track metadata convert dialog lists AAC next to the other targets.
Apple Music lyrics gain a 'eLRC word sync' switch (default off). When disabled the pax-to-LRC formatter strips inline word timestamps, producing line-synced LRC that is safer for players that choke on eLRC; enabling it restores the previous word-by-word behaviour. The change propagates through SetLyricsFetchOptions and invalidates the global lyrics cache on toggle.
Broad l10n migration: roughly 400 previously hardcoded English strings across queue, settings, track metadata, repo, audio analysis, setup and extension screens now live in the ARB catalog, with matching plural/placeholder forms. No behaviour change beyond localisation. Existing and new unit tests (lyrics eLRC toggle and Dart settings round-trip) pass.
Bump the history schema on both the Kotlin finalizer and the Dart database to v9, adding bitrate (kbps) and format (codec label) columns, and let the download flow fill them from backend/probe metadata so lossy downloads keep a 'AAC 256kbps' label instead of falling back to the stored placeholder. Library filtering and the track metadata screen now read format/bitrate directly from those columns, which also fixes mis-tagged quality badges after re-downloading a track at a different format.
Additional fixes bundled in: EditFileMetadata now routes ReplayGain writes through the M4A path whenever the file starts with ftyp (fixing .flac files that actually hold MP4 containers); GetM4AQuality falls back to the first trak/mdia/mdhd duration when mvhd is zero so EAC3 streams no longer report 0s; and both Kotlin and Dart reject bitrate values below 16 kbps to prevent probe noise from surfacing as '0 kbps' labels. New unit tests cover the EAC3 mdhd fallback and the mis-named M4A replaygain path.
GetM4AQuality now recognizes fLaC, alac, ec-3, ac-3, and ac-4 sample entries and parses the MP4 FLACSpecificBox so library entries carry the real codec rather than the container extension. The AudioQuality struct exposes Codec and Bitrate fields (with an estimator for compressed streams), and ReadFileMetadata publishes format + audio_codec so Flutter and Kotlin can make format decisions based on the actual stream.
Downstream: library_scan labels M4A-family items as flac/alac/eac3/ac3/ac4/m4a, zeroes the bitrate for lossless formats, and the filter UI + quality badges use the codec-derived format instead of only the file extension. Scans and SAF importers also accept .mp4 and .aac file extensions. New unit tests cover codec name mapping and MP4 FLACSpecificBox decoding.
Replace in-memory list merging in the queue tab with fully database-
backed pagination using ATTACH DATABASE to join library and history
tables in a single UNION ALL query.
Queue tab:
- Remove localLibraryAllItemsProvider and _queueHistoryStatsProvider
- Add _queueLibraryPageProvider and _queueLibraryCountsProvider backed
by LibraryDatabase.getQueueTrackPage/getQueueCounts/getQueueAlbumPage

_libraryPageLimit growing by 300 per batch
- Album/single/total counts computed via SQL GROUP BY aggregates
History database (v5 -> v8):
- v6: add idx_history_track_artist index
- v7: add history_path_keys table for cross-DB dedup, backfill from
existing rows
- v8: add spotify_id_norm, isrc_norm, match_key normalized columns
with indexes, backfill from existing data
- Add getAlbumTracks, findByTrackAndArtist, getGroupedCounts,
existsTrack, findExistingTrack, existingTrackKeys batch lookup

Library database (v7 -> v8):
- v8: add library_path_keys table for cross-DB dedup
- Add getQueueTrackPage, getQueueCounts, getQueueAlbumPage with
ATTACH DATABASE for cross-DB UNION ALL queries
- Dedup local items against history via path_keys JOIN
- All write/delete paths maintain library_path_keys consistency
Download history provider:
- Load only 100 recent items into state.items at startup
- Store lookupItems as immutable List field instead of recomputing
from maps on every access
- Add async fallback to DB in _putInMemoryHistory for items outside
the 100-item window
- Add downloadHistoryPageProvider, downloadHistoryGroupedCountsProvider,
downloadedAlbumTracksProvider, downloadHistoryBatchExistsProvider
- Add catchError to adoptNativeHistoryItem async block
- Fix removeBySpotifyId to query actual DB count instead of decrement
Screen migrations:
- album/artist/playlist/home screens use async DB lookups instead of
sync in-memory state for track existence and playback resolution
- downloaded_album_screen uses downloadedAlbumTracksProvider
- library_tracks_folder_screen uses downloadHistoryBatchExistsProvider
for skip-downloaded checks and cover resolution
Replace the full in-memory List<LocalLibraryItem> in LocalLibraryState
with a lightweight lookup index (ISRCs, matchKeys, filePathById) and
database-backed FutureProvider.family pagination providers.
Database changes:
- Add library schema v7 with normalized lookup columns (track_name_norm,
artist_name_norm, album_name_norm, album_artist_norm, match_key,
album_key) and corresponding indexes
- Backfill normalized columns on migration from v6
- Add getPage, getPageCount, getAlbumPage, getAlbumCount, getLookupIndex,
getCoverPaths, getByFilePath, findFirstByTrackAndArtist DB methods
Provider changes:
- LocalLibraryState no longer holds items list; uses totalCount and
loadedIndexVersion for change tracking
- Deprecate synchronous getByIsrc/findByTrackAndArtist (return null);
add async findExistingAsync, getByIsrcAsync, getById on notifier
- Add localLibraryPageProvider, localLibraryAlbumPageProvider,
localLibraryAllItemsProvider family providers for paginated access
- Add localLibraryCoverProvider and localLibraryFirstCoverProvider
for async cover path resolution from DB
Screen migrations:
- album/artist/playlist screens use findExistingAsync for playback
- library_tracks_folder_screen uses async cover providers and
existsInLibrary for local library indicator
- queue_tab watches localLibraryAllItemsProvider instead of state.items
- library_settings_page uses state.totalCount
- playback_provider uses findExistingAsync
Track metadata screen:
- Replace pushReplacement navigation with in-place state swap using
AnimatedSwitcher for smooth cross-fade transitions on track swipe
- Add metadataLoadGeneration counter to prevent stale async callbacks
- Reset all transient state (lyrics, cover, file check) on track change
UI and UX improvements across the library and queue screens.
- Add pinch-to-zoom for library grid views with animated extent
transitions via _AnimatedLibrarySliverGrid widget
- Replace fixed grid column count with responsive maxCrossAxisExtent
- Add smooth fade-in for cover images (local files via frameBuilder,
network via CachedCoverImage fadeInDuration/fadeOutDuration params)
- Refactor track metadata swipe navigation from push+pop to
pushReplacement to prevent route stack accumulation
- Convert adjacentHorizontalPageRoute to MaterialPageRoute subclass
to support pushReplacement with proper transition semantics
- Add five new metadata completeness filters: missing track number,
missing disc number, missing artist, incorrect ISRC format, and
missing label
- Expose trackNumber, discNumber, isrc, and label on
UnifiedLibraryItem for filter support
- Tighten metadata completeness definition to include all new fields
- Extract home_tab.dart helpers/widgets into home_tab_helpers.dart and home_tab_widgets.dart using Dart part files
- Extract queue_tab.dart helpers/widgets into queue_tab_helpers.dart and queue_tab_widgets.dart using Dart part files

- DRY platform_bridge.dart: extract common JSON decode patterns into reusable helper methods (_decodeRequiredMapResult, _decodeNullableMapResult, _decodeMapListResult, _decodeStringListResult)
Remove Tidal from built-in provider registry (metadata, search, download,
URL parsing) and delete tidal.go. Introduce extension runtime APIs for
lyrics lookup (getLyricsLRC), ISRC existence check (checkISRCExists), and
ISRC index management (addToISRCIndex). Refactor extension download response
construction into normalizeExtensionDownloadResult/overlayExtensionDownloadMetadata
helpers with AlreadyExists support and ISRC indexing. Switch download mirrors
to DoRequestWithUserAgent for ISP blocking detection. Add 50+ new
localization keys and accessibility labels across all supported locales.
Replace hardcoded Tidal/Qobuz switch/case with builtInProviderSpec registry
pattern. Unify searchTidalAll/searchQobuzAll into searchProviderAll,
getDeezerMetadata/getTidalMetadata/getQobuzMetadata into getProviderMetadata,
and parseDeezerUrl/parseQobuzUrl/parseTidalUrl into parseProviderUrl. Remove
extension-specific getAlbum/Playlist/ArtistWithExtension in favor of generic
getProviderMetadata routing. Extract provider UI helpers into
provider_ui_utils.dart. Preserve track_number fallback for zero-value
TrackNumber in album/playlist track lists.
- Add reference-counted cancel entries to prevent premature cleanup when multiple operations share the same itemID
- Propagate cancellation to DownloadTrack, DownloadWithFallback, DownloadWithExtensionsJSON, extension providers, and ISRC search
- Fetch album artist from MusicBrainz when missing during download and re-enrich
- Make ALBUMARTIST tag nullable to avoid writing artistName as album artist
- Add home feed 'Off' option in extension settings
- Skip deezer in download provider priority sanitization
