The DB-backed pagination migration left the old in-widget filter/unification
pipeline behind three unused_element ignores; every helper, cache field, and
isolate entry point below them was reachable only from that dead root.
- 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)
queue_tab.dart was 7,567 lines with a single 7,300-line State class.
Continue the existing part-file split by moving six cohesive method
clusters into private extensions on _QueueTabState (same library, so
private state access is unchanged): selection mode, navigation/open
actions, collection item builders, filter UI, batch actions, and
queue/library item builders. setState calls in the parts go through a
_setState forwarder since @protected members cannot be called from
extensions. queue_tab.dart is now 2,462 lines.
