- 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)
- drop unused widgets (AnimatedStateSwitcher, GridSkeleton,
adjacentHorizontalPageRoute, buildRemovalAnimation, SwingIcon,
BottomSheetOptionTile) and empty _buildInfoCard placeholders
- drop test-only Go wrapper methods (GetDownloadURL, MatchTrack,
CheckAvailability 7-arg, CustomSearchForItemID) and their parsers
- drop unused httputil getters/validators and hand-rolled base64
decoder in favor of encoding/base64
- remove unused riverpod_generator dev dependency
Both carried yet another copy of the collapsing detail header.
AlbumDetailHeader gains appBarTitle (selection-aware toolbar title) and a
leading override for the folder screen's close/back switch. The playlist
header adopts the album layout (bottom-anchored content, 0.85 gradient,
length-adaptive title size, scrim only when blurred) instead of its
drifted centered variant; motion-banner and pill-chip meta are preserved
through the slots.
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.
Every settings-style page carried the same 40-line SliverAppBar block;
titles, custom leadings (discard-confirm back handlers), and action
buttons are preserved through the widget's slots.
Single homes for logic that was copy-pasted across screens: the settings
collapsing header, album detail header (online screen's design as the
reference), selection pill button + bottom-bar chrome, disc separator
chip, error card, cover URL upgrade, byte/clock formatting, duration
extraction, UnifiedLibraryItem (moved out of the queue_tab library so
other screens can import it), and the batch convert/ReplayGain engine
keyed on it.
_AlbumTrackItem and _PlaylistTrackItem were line-for-line identical
except for the leading widget and whether the artist name is clickable;
both are now parameters of a shared TrackListTile.
Extract InLibraryBadge (pasted verbatim in five screens) and
playLocalIfAvailable (duplicated in three) into shared code, and delete
SearchScreen, LibraryPlaylistsScreen, and CollapsingHeader, which are
imported nowhere in lib/.
Port of the explicit-content indicator from SpotiFLAC-Web (issue #456):
- Go: add explicit to ExtTrackMetadata (parsed generically from any
extension via explicit/is_explicit/isExplicit), TrackMetadata, and
AlbumTrackMetadata; built-in Deezer maps explicit_lyrics and
explicit_content_lyrics == 1
- Dart: add explicit to the Track model with a tolerant
parseExplicitFlag helper wired into all backend track parsers
- UI: new ExplicitBadge rendered through buildQualityBadges on album,
playlist, search, and home track rows
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.
Raise default extension health cache to 10 minutes with a 1-minute floor
and a shorter TTL for unknown status. Mirror the TTL rules in the Go
backend and stop force-refreshing health checks from the download
service picker on every open.
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.
Move hardcoded strings in library settings, announcement link errors,
and unknown track title/artist fallbacks to AppLocalizations. Sync
locale-dependent fallback strings from MainShell.
- 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
Add a MotionHeaderBanner (video_player) that plays a looping muted HLS header video with a static image fallback for artist, album, and playlist screens. The Go backend now exposes header_video, header_image, and audio_traits from extensions. Album/playlist headers show the release year and Dolby Atmos / Lossless badges inline, full date and song count in a footer, a centered square cover when no video is present, and a full-bleed video when one is.
Add a preview player provider and PreviewButton, a previewUrl field on Track (parsed from search and local redownload), preview buttons in search results, and stop the preview on navigation/tab change via per-tab navigator observers. Includes preview play/stop/unavailable localization strings.
Cache health results after each check, add a force flag to bypass the cache when the download picker opens or a service is selected, guard stale concurrent results via a per-extension request serial, and treat DNS lookup failures as indeterminate/transient.
Extract the BETA pill into a reusable BetaBadge widget in settings_group.dart and add titleTrailing support to SettingsItem. Show the badge on the Backup & Restore entry in the settings list, and reuse the shared widget in the download settings page (removing the duplicated private badge).
Resolve artist taps by id when available and fall back to name-similarity matching instead of blindly picking the first search result. Pass provider id at more call sites and map multiple artist ids positionally to their names.
- 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
FFmpeg doesn't always embed lyrics correctly to MP3 files. This adds
manual ID3v2.3 USLT (Unsynchronized Lyrics) frame writing after FFmpeg
metadata embedding to ensure lyrics are properly stored.
Implementation:
- Extract lyrics from metadata (UNSYNCEDLYRICS or LYRICS key)
- Build ID3v2.3 compliant USLT frame with UTF-16LE encoding
- Insert or replace USLT frame in existing ID3v2.3 tag
- Create new ID3v2.3 tag if file has no ID3 header
- Skip gracefully for unsupported ID3 versions or flags
Also includes minor audio analysis improvements:
- Consistent dynamic range calculation (peak - rms)
- Filter out 'unknown' and 'n/a' labels
- Add -vn -sn -dn flags for more robust stream selection
Audio Analysis Enhancements:
- Display codec name and container format
- Show decoded sample format (s16, s32, fltp, etc.)
- Add LUFS integrated loudness measurement (broadcast standard)
- Add true peak measurement (dBTP)
- Detect and count clipping samples per channel
- Estimate spectral cutoff frequency (helps detect fake upscales)
- Show per-channel statistics (Peak, RMS, DR, Clip count)
UI Improvements:
- MetricChip now handles long text with ellipsis
- Constrained max width for better layout
Cache version bumped to 4 to force rescan with new metrics.
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.
Introduce AppRemoteConfigService which fetches a platform/version/locale-aware JSON payload from api.zarz.moe/v1/spotiflac-mobile/config and caches it in SharedPreferences. main_shell shows a one-shot announcement dialog (respecting dismissible, CTA, time window and version gates) when no update prompt is pending; dismissed IDs are persisted so each announcement surfaces only once.
Tweaks bundled in: the service health dot loses its blur halo in favour of solid Material 3 tones, and AppInfo gains the remote config endpoint constant. The share listener and SAF migration hook stay synchronous inside the post-frame callback so share-intent URLs never race the network-bound checks.
New unit tests cover the announcement CTA/active-window rules.
The audio analysis card used to read from a persistent cache but offered no way to refresh the result when the underlying file had been re-downloaded at a different quality (for example, re-downloading a track as FLAC after capturing it as AAC). Add an explicit rescan control that clears the cached JSON + spectrogram, reruns the FFmpeg probe and analysis pipeline, and swaps in the fresh data while keeping the loading copy distinct from first-run analysis. A retry button is also exposed in the error card so transient failures do not require navigating away.
All audio_analysis strings now have a Re-analyze / Re-analyzing pair in the ARB catalog so every locale can translate them independently.
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
All search, metadata, and download providers are now exclusively
supplied by extensions. The built-in provider registry that previously
exposed Deezer/Tidal/Qobuz as hardcoded providers is fully removed.
Removed across Go, Dart, Kotlin, and Swift:
- BuiltInProviderSpec class, registry, and all accessor helpers
- SearchProviderAllJSON, GetBuiltInProvidersJSON, ParseProviderURLJSON,
ParseDeezerURLExport Go exports and their platform channel bindings
- Built-in provider items in search dropdown, service picker, and
provider priority UI lists
- provider_ui_utils.dart helper file
Deezer metadata enrichment (ISRC lookup, extended metadata, cover
upgrade) remains fully functional through direct DeezerClient calls
in the download pipeline — these are not part of the provider
registry and are unaffected.
Mark deezer as a retired built-in metadata provider so stale user
priority lists are cleaned up on next launch.
Introduce a service-owned download worker that offloads the full
download-and-finalize pipeline to DownloadService on Android, keeping
downloads alive independently of the Flutter UI process.
Key changes:
- Extract SAF download logic from MainActivity into SafDownloadHandler
- Add NativeDownloadFinalizer for Kotlin-side decryption, format
conversion, metadata embedding, ReplayGain, post-processing, and
history persistence
- Extend DownloadService with native queue management (start, pause,
resume, cancel) using coroutine-based worker with AtomicFile snapshots
- Add Dart-side orchestration: snapshot polling, run-id correlation,
adoption on app restart, and fallback to Dart queue
- Forward embedReplayGain, tidalHighFormat, and postProcessingEnabled
through Go backend DownloadRequest struct
- Add nativeDownloadWorkerEnabled setting with UI toggle
- Make DownloadQueueLookup collections unmodifiable
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.
