Mirror the library_schema and library_row_mapper split: HistorySchema owns
create, upgrade, index creation and backfills, HistoryRowMapper owns the
JSON/row mapping and the derived normalized and queue-sort columns. SQL text
is unchanged. Tests that read the history CREATE TABLE and index text now
read history_schema.dart.
The queue provider library mixed pure, notifier-free helpers (processing
gate, storage-write recovery, native worker status/progress mapping,
batch album-artist normalization) with the notifier. They now live in a
standalone file that the library imports and re-exports, so existing
importers are unchanged.
BouncingIcon, SlidingIcon and SpinIcon are standalone widgets, so they now
live in lib/widgets/nav_destination_icons.dart. The SAF repair, upgrade intro,
update, announcement and SAF migration prompts move into a part as an
extension on the shell State; the call sites in initState are unchanged.
The setup screen State mixed permission and folder logic with the step
builders. Move the builders and the step widgets into a part as an extension
on the State; the two setState calls in moved code go through a _setState
forwarder.
The screen file mixed state, a dozen private widgets and the curve painter.
Move the widgets and the painter with its helpers into part files; code is
unchanged.
The two Rewind providers move to lib/providers and are re-exported from the
screen so existing imports keep working. Story, slides and widgets become
part files of the screen library. No behavior change.
Options group, quick-select button, switch field, selection field and
section card become public StatelessWidgets in metadata_editor_fields.dart
with unchanged build bodies; State fields they read (color scheme, fetching
flag) are now constructor parameters.
Cover editor members and auto-fill members move to extensions in part
files; bodies are unchanged except setState goes through a _setState
forwarder, as in the other State part files.
The provider and cover-size pickers shared the sheet shell and row layout.
Both now go through _showEditorOptionPicker<T>; per-picker differences
(label ellipsis, which context supplies the check icon theme) stay as
parameters.
The 440 line build method now computes shared state once and composes one
private builder per sliver group (header, intro, search bar, filters, recent
access, home sections, explore, explore skeleton, search results). Conditions,
order, keys and provider watches are unchanged.
ExtensionAlbumScreen, ExtensionPlaylistScreen and ExtensionArtistScreen and
their exclusive helpers lived in home_tab_widgets.dart, a part of the home tab
library. They now live in extension_collection_screens.dart, re-exported from
home_tab.dart so existing importers keep working. artist_screen.dart and
clickable_metadata.dart import the new library directly instead of home_tab.
The filter sheet moves into its own part. The sort chips now iterate
_librarySortModes with _sortLabel (same modes, labels and order), and the
source, quality and metadata groups use value/label tables since their chips
differ only in value and label.
Pure moves: download label helpers and the download dialogs become parts of
the queue_tab library, and the animated sliver grid becomes a public widget
in lib/widgets since it uses no private state.
Top-level helpers and secondary classes (codec isolates, cache entries,
event and SAF models, the native worker job state and the NDJSON scan
file) move verbatim into part files grouped by concern. The
PlatformBridge class body is unchanged apart from three region comments
over groups that were already contiguous.
platform_bridge.dart was one 2900-line file mixing eight concerns; the
static class cannot be split without changing its type, so this moves
what can move mechanically and leaves the class intact for call sites
and the channel mocks in tests.
The log buffer polls the native backend, so isFromGo, the Go log polling
methods and their private state now use native names. Comments that still
described the backend as Go are reworded. No string literals changed.
Delete Dart members that have no reference in lib, test or integration_test:
unused player configuration helpers and event streams, two PlatformBridge
wrappers, database and export helpers, the unused global logger and the
now pointless 'hide log' imports.
Drop the gomod renovate rule, the stray em dash in crowdin.yml and the migration wording in check_rust_backend.sh. Rename the SMB fixture servers so test_*.py discovery no longer implies unit tests, and describe supported_locales.dart as hand-maintained since its generator never existed.
The month-year DateFormat was rebuilt for every loaded row and every
fast-scroller drag label; it is now cached per locale tag. Constant-pattern
RegExp objects built per call (or per word) are now static or top-level.
Nothing read parentPageController, parentPageIndex or nextPageIndex, and the
Library tab root watched showExtensionStore only to compute them, so toggling
that setting rebuilt the tab for nothing. No caller passed the fast scroller
onDragStart/onDragEnd callbacks.
Applying a preset replaced every setting, so built-in presets silently
turned automatic headroom, the limiter and the compressor back on and
reset balance. Presets now carry only the curve, preamp, bass and treble.
The active preset is matched on the same fields, so it no longer shows as
Custom once headroom is off.
The empty lyrics page offers Search online, which asks the enabled lyrics
providers in their configured order. The result is shown in the player
only and never written to the file; a late result is dropped after the
track changes, and a miss says so.
Add two keyless providers that serve Apple Music TTML: lrc.red, matched by
recording, and BetterLyrics, which answers songs it has already cached.
TTML is read into the first-party Apple line structure, so vocal sides,
backing groups, word timing, translations and romanization share one eLRC
formatter. The XML depth guard moves to core so both readers use it.
SpotiFLAC-Mobile Lyrics becomes its own provider instead of a fallback
inside Apple Music. New defaults are Apple Music, lrc.red, SpotiFLAC-Mobile
Lyrics, LyricsPlus and LRCLIB. Migration 13 moves untouched defaults to the
new list and keeps the former fallback right after Apple Music in custom
orders. Replace the dead LyricsPlus Workers mirror.
Without a feed, the Material Home now greets in its header with a
prompt picked once per launch, keeps import and paste out of the
resting search field, and fills the page with Continue listening,
player shortcuts, Recently added tracks from the whole Library and the
most played tracks of the last four weeks.
Single-choice sheet rows still built their own checkmark trailing, with
inconsistent colours, so only three rows used AppSheetOption.choice. Move
the remaining sixteen rows to it, drop the now unused colour plumbing, and
remove a duplicate Semantics wrapper that announced selection twice.
