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.
Add a localized description header and Material 3 styling (rounded
corners, scrollable layout, surface color) to the album folder structure
picker in Files settings.
- Queue/Library: switch from growing-limit refetch to offset-based append pagination per filter/search/sort, with page cache reassembly and protected-page eviction to avoid top-of-list gaps
- Queue/Library: watch only the active filter page instead of all/singles/albums simultaneously; filter mode follows PageView swipe and tab tap
- library_database: combine three union-based count queries into a single round-trip
- library_scan: parallel scan of non-CUE audio files with a bounded 2-4 worker pool, preserving order, progress, and cancellation; CUE handling stays sequential
- extension_manager: cache compiled goja.Program per extension and RunProgram per isolated download instead of re-reading and re-parsing index.js
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).
Replace the custom _ActionCard/SwitchListTile layout with the shared SettingsSectionHeader + SettingsGroup + SettingsItem/SettingsSwitchItem components used across the other settings pages, so spacing, grouping and switch styling match. Busy state shows an inline progress indicator on the action row.
file_picker has no stable release compatible with win32 ^6.x (required by device_info_plus/share_plus/connectivity_plus). Its Windows FFI code is compiled even for Android builds, so a win32 override breaks compilation. Revert file_picker to 12.0.0-beta and restore the original pickFile usage. Other Flutter/Go dependency updates remain on latest stable.
Add a setting that relaxes the SSRF guard so extensions and built-in network code can reach private/local/loopback targets, for users routing traffic through a local proxy or custom DNS. Disabled by default. Wired end-to-end: Go backend (SetAllowPrivateNetwork toggles isPrivateIP guard), Android/iOS platform bridge, Dart settings model/provider, and a toggle in Download settings.
Flutter: bump connectivity_plus, device_info_plus, share_plus, receive_sharing_intent, path_provider, flutter_local_notifications to latest stable. Revert file_picker from 12.0.0-beta to 11.0.2 stable and migrate pickFile (singular) to pickFiles. Add win32 ^6.0.1 dependency_overrides to resolve the win32 5 vs 6 conflict between file_picker stable and device_info_plus (Windows-desktop-only transitive dep, not used on mobile targets). Go: update goja, golang.org/x/mobile, golang.org/x/tools, regexp2/v2 to latest.
Back up the store registry URL plus each installed extension (id, version, enabled flag and settings) and restore them on a new device by reinstalling from the store and re-applying settings. Secret-flagged settings (tokens/API keys) are excluded by default behind an opt-in 'Include extension credentials' toggle. Device-bound signed sessions are never backed up. Settings are merged on restore so omitted secrets are not wiped; failed reinstalls are reported.
Add a Backup & Restore page that exports app settings, download history, liked tracks, wishlist, playlists (with cover images) and favorite artists into a single JSON file, and restores them on another device. Settings restore preserves device-specific storage location (SAF tree URI, download dir). Includes EN strings and ID translations.
Add a playlist position token usable in filename templates, plumbed from the playlist screen through the download queue to the Go backend. Auto-prefix playlist downloads with the position when the template lacks the token. Includes Go filename test.
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.
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.
Replaces the cropped BoxFit.cover header with a blurred cover backdrop plus the full square cover centered, so covers with baked-in text are no longer awkwardly cropped. Title, track count and actions now sit in one centered column that adapts to header height.
Active downloads now render as the first tiles of the library list/grid instead of a separate top section, with a compact Downloading header that animates in/out. Completed items hand off seamlessly via a short-lived bridge tile (with cover precache) so the song never blinks out, and the order is reversed so the soonest-to-finish sits next to where it lands.
- iOS: begin/end UIBackgroundTask while a download queue is active so in-flight downloads survive backgrounding for the limited window iOS allows
- extensions: serialize install/upgrade/remove in the Go manager (mutationMu) and in the Dart store provider to stop concurrent goja VM teardown/reload from hard-crashing the app
- main: add runZonedGuarded + FlutterError/PlatformDispatcher onError so uncaught Dart errors are logged, not fatal
- batch convert sheet: precompute localized title/label before showModalBottomSheet to avoid Localizations lookup via a deactivated context
- 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.
- Rename downloadProviderMatchesBuiltIn -> downloadProviderReplacesLegacyProvider
- Rename Tidal DASH ffmpeg helpers and lossy format pickers to generic names
- Add utils.decryptCTRSegments crypto API + raw/bytes file read path in extension runtime
- Update l10n strings/descriptions to drop hardcoded service names
- Bump version to 4.5.7+134
The download API only permits one request at a time, so parallel
downloads are removed to avoid wasted/blocked API calls. Downloads
now always run sequentially (one track at a time).
- Drop concurrentDownloads from AppSettings + JSON serialization
- Remove setConcurrentDownloads and the settings UI (1-5 chips + warning)
- Strip optionsConcurrent* l10n keys from all ARBs and regenerate
- Rework queue worker into _processQueueSequential (single active download)
- Update marketing copy and adjust tests
- Dart: _metadataMatchIsConfident now handles album-only case (title empty)
by adding albumMatches fallback branch
- Go: selectBestReEnrichTrack treats placeholder values (Unknown Title,
Unknown Artist) as empty via isPlaceholderReEnrichValue, so album-based
fallback filtering works correctly
- Add test for placeholder album fallback in selectBestReEnrichTrack
- 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
- Extract _formatDownloadProgressLabel() for cleaner code
- Show received/total size when bytesTotal is available
- Estimate total size from progress when only bytesReceived is known
- Add text overflow handling with ellipsis
New lyrics providers using Paxsenix API:
- Spotify: Synced lyrics from Spotify
- Deezer: Synced lyrics from Deezer
- YouTube: Lyrics from YouTube
- Kugou: Lyrics from Kugou (Chinese service)
- Genius: Plain text lyrics from Genius
Implementation:
- Add lyrics client implementations for all providers
- Smart search result scoring based on track name, artist, and duration
- Support for both synced (LRC) and unsynced lyrics formats
- Fallback search with simplified track names and primary artist
UI updates:
- Add provider entries to lyrics priority settings page
- Add display names for new providers in settings
- Replace inline format detection with convertibleAudioSourceFormat()
- Replace inline conversion rules with canConvertAudioFormat()
- Add unit tests for Dolby format detection and conversion rules
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.
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.
