Pre-existing bug, reproduces identically before this branch's changes:
_editarGrupo (pantalla_ajustes_grupos_favoritos.dart) and
_editarTamanoMaximo (pantalla_ajustes_grabaciones.dart) each created a
TextEditingController, awaited showModalBottomSheet, then disposed the
controller immediately on resolve - racing the sheet's own close
animation, which still holds a bound TextField for a couple more
frames. Manifests as "A TextEditingController was used after being
disposed" plus a couple of cascading framework-internal symptoms.
Fix: extract each sheet's content into its own StatefulWidget
(_HojaEditarGrupo, _HojaTamanoMaximo) that owns the controller in its
own State. Flutter only calls State.dispose() once the widget is
actually removed from the tree, i.e. after the close animation
finishes, so there is no dispose-timing decision left for the caller
to get wrong.
_editarGrupo's own test previously suppressed the crash via a
FlutterError.onError override instead of fixing it; that suppression
is removed here. _editarTamanoMaximo had no coverage at all for this
interaction; added it. Strict TDD: confirmed both sites fail without
the fix (RED) before applying it (GREEN).
Restyle the Ecualizador settings screen to the new visual language while
keeping the equalizer at 5 bands (spike-resolved, Engram id 2498 - band
count is device-reported via just_audio's AndroidEqualizer, not app-chosen;
the approved mockup's 7 sliders would silently no-op on typical hardware).
- Restyle EcualizadorWidget in place: strip its internal title + preset
chip row (the pushed screen's header now carries the title), add a
habilitado parameter that greys/disables every slider when EQ is off.
Widen PresetsEcualizadorWidget additively (personalizados param) so
custom presets can join the chip row without a second implementation.
- Add servicio_presets_personalizados.dart (new file, own SharedPreferences
key eq_custom_presets_v1) for custom EQ preset persistence - kept out of
servicio_ecualizador.dart, which has an empty-git-diff success criterion
for this change. preset_ecualizador.dart is unchanged: a custom preset is
just a PresetEcualizador with a user-supplied name.
- Extend EstadoEcualizador with presetsPersonalizados,
guardarPresetPersonalizado (validates non-empty name),
eliminarPresetPersonalizado. The load is a new explicit
cargarPresetsPersonalizados(), deliberately NOT folded into
cargarPersistido(): that method is exercised ~30 times by
estado_ecualizador_test.dart (protected, must stay unmodified) via Fakes
only, with no SharedPreferences awareness in that file.
- Build out the Ecualizador screen body: base-vs-per-station explainer
banner, a "Salida activa" row surfaced on the main screen (previously
Advanced-only), an "Emisoras con ajuste propio" drill-down sourced from
the existing presetsPorEmisora map, and a "Guardar como preset" action.
New coverage lives in new files rather than touching the three protected
EQ test files: ecualizador_widget_test.dart (component-level, did not
exist before this commit), servicio_presets_personalizados_test.dart, and
estado_ecualizador_presets_personalizados_test.dart. servicio_ecualizador.dart,
servicio_audio.dart and the three protected EQ test files keep an empty
git diff. Full suite: 713/713 green (2 skipped, unchanged), up from 682.
size:exception - realized 1,954 changed lines (25 files, plus this docs
update) against the 400-550 forecast: lib/ + ARB alone is ~650 lines, near
the top of the forecast band by itself since this WU also had to build out
a screen body WU3a only stubbed; the rest is 4 test files (675 lines) and
11 new ARB keys regenerating 13 lib/l10n/gen files (~546 lines) - the same
pattern every prior work unit in this branch has hit. Not splittable: WU14
reuses this unit's editor component by exact runtime type and cannot begin
until this lands as a whole.
Moves the AUDIO group (Ecualizador, Salida de audio, Temporizador de
sueno) and the EMISORAS group (Grupos de favoritos, Emisora preferida,
Emisoras personalizadas, Orden de listas) out of pantalla_ajustes.dart
into 7 new lib/pantallas/ajustes/*.dart screens, each wrapped in
PluriPushScaffold. The root now reaches them through FilaAjuste rows
under two new GrupoAjustes cards (lib/pantallas/ajustes/widgets/
fila_ajuste.dart), per design ADR-3.
Verbatim-move rule applied throughout: only each section's panel header
(icon + title, sometimes a status chip) was removed, since the pushed
screen's own 56px header now carries the title. Two sections whose
header row carried a real action (Temporizador de sueno's "Add",
Grupos de favoritos' "Add list", Emisoras personalizadas' "Add") kept
that action in the body instead of dropping it.
size:exception (move-only diff, pre-recorded at design/tasks time):
34 files, ~4250 changed lines excluding the 13 auto-regenerated l10n
files (~90 more lines there) - higher than the 800-1000 estimate
because that estimate covered the 7 production screens but not the
matching 7 new test files (task 3a.2), one of which relocates ~10
pre-existing device-management test cases verbatim. Business logic is
untouched; app.dart's import of pantalla_ajustes.dart is unchanged.
Correction to tasks.md 3a.1/3a.8: those two lines describe the combined
WU3a+WU3b end state ("4 grouped nav lists", "<400 lines"), matching
design ADR-3's own aggregate blast-radius note - not a WU3a-only claim.
This commit converts only the 2 groups that are WU3a's job; the root
is 788 lines with 5 sections (Grabaciones, Musica local, Idioma,
Backup, Info) still inline, reachable, and unchanged, pending WU3b.
Two new ARB keys (settingsGroupAudioTitle, settingsGroupStationsTitle),
en/es only per the WU1 precedent - all 7 detail-screen titles reuse
existing keys. Discovered and worked around, without touching app
code: Directory.systemTemp hangs real dart:io writes in this sandbox,
and pumpAndSettle() cannot settle while a screen shows an indeterminate
CircularProgressIndicator - both are test-only concerns, documented
inline where hit.
Tests: 560 -> 579 (32 in this commit's scope, net +19 after retiring
13 relocated cases from the old combined pantalla_ajustes_test.dart).
flutter analyze: unchanged at 1 pre-existing info. git diff is empty
for navegacion_auto.dart, servicio_ecualizador.dart and
servicio_audio.dart; pantalla_alarma_sonando_dismiss_guard_test.dart
untouched.
