Archive Report: EQ Device Auto-Switch UX

Change Name: eq-device-autoswitch-ux
Archive Date: 2026-06-28
Status: COMPLETE — All requirements met, all tests passing, ready for closure.

Executive Summary

The eq-device-autoswitch-ux change is COMPLETE and ARCHIVED. All 18 spec scenarios pass. Device startup seeding bug fixed. Device rename persistence, connection indicators, and edit modal fully implemented. 231 tests green, analyzer clean. 2 CRITICAL and 3 WARNING issues identified in initial verification were all resolved in the fix round. Delivered via 3 chained PRs.

Change Intent

Enable multi-device EQ management with:

  • Startup device seeding: Call obtenerDispositivoActual() in cargarPersistido() to seed device at app launch
  • Device rename persistence: eq_nombres_dispositivos_v1 SharedPreferences key for custom device names
  • Display name fallback: customName → platformName → deviceId
  • Connection indicator: Green dot on active device in Settings
  • Edit modal: Tap device to open bottom sheet with rename TextField + embedded EcualizadorWidget

Verification Results

Initial Verdict (First Verify Run)

PASS WITH WARNINGS — 2 CRITICAL, 3 WARNING, 2 SUGGESTION issues found.

CRITICALs (both fixed)

CRITICAL-1: Toggle-off no-op for rename not implemented

  • Issue: No guard on _eqMultiDeviceEnabled in renombrarDispositivo()
  • Fix: Added if (!_eqMultiDeviceEnabled) return; at method entry + 2 new tests
  • File: lib/estado/estado_ecualizador.dart
  • Tests: test_renombrarDispositivo_cuando_multiDispositivoDeshabilitado_esNoOp (2 variants)

CRITICAL-2: EQ changes in modal discarded on save

  • Issue: No public method to save preset to presetsDispositivo[deviceId]; modal only called renombrarDispositivo()
  • Fix: Added guardarPresetDispositivo(String deviceId, PresetEcualizador preset) method; modal now calls it
  • Files: lib/estado/estado_ecualizador.dart, lib/pantallas/pantalla_ajustes.dart
  • Tests: 4 new tests covering device-level preset save, with/without active device

WARNINGs (all fixed)

WARNING-1: Platform name fallback unreachable from UI

  • Status: FIXED in implementation — _FilaDispositivo now receives and passes DispositivoAudio.nombre to fallback chain
  • No regression risk: Fallback chain already handles null/empty gracefully

WARNING-2: 7 locales missing translations (pt, it, ja, zh, ru, bn, id)

  • Fix: Added all 5 eqDevice* keys to all 7 locale files + ran flutter gen-l10n
  • Files: lib/l10n/app_pt.arb, app_it.arb, app_ja.arb, app_zh.arb, app_ru.arb, app_bn.arb, app_id.arb

WARNING-3: FakeServicioEcualizador drops nombresDispositivos on save

  • Fix: Updated guardarPrincipal() and guardarActivo() to preserve nombresDispositivos in reconstructed config
  • File: test/helpers/fakes.dart
  • Tests: 2 new tests verify preservation

Final Verdict (After Fix Round)

ALL PASS — 231/231 tests green, flutter analyze clean, no issues remaining.

Tasks Delivered

Phase 1: Service Layer (PR 1)

  • 1.1–1.7: nombresDispositivos persistence in SharedPreferences

Phase 2: State Layer (PR 1)

  • 2.1–2.10: Startup seeding + renombrarDispositivo() + guardarPresetDispositivo() + guard

Phase 3: Settings UI (PR 2)

  • 3.1–3.2, 3.4–3.8: Device rows + modal (3.3 scrollability test deferred, 3.9 extraction skipped)

Phase 4: Localization (PR 2)

  • 4.1–4.4: 5 keys in 13 locale files + flutter gen-l10n

Phase 5: Cleanup (PR 3)

  • 5.1–5.5: All 231 tests passing, no TODOs, clean analyzer output

Chained PRs Delivered

PR Title Base Files Lines Tests Status
#1 feat(eq): per-device EQ rename + persistence main 3 ~150 6 MERGED
#2 feat(eq): device modal + indicators PR #1 4 ~220 4 MERGED
#3 test(eq): complete modal + device tests PR #2 2 ~45 4 MERGED

Known Deferred / Out of Scope

  1. Task 3.3: Modal scrollability widget test (viewport test — LOW PRIORITY, not blocking)
  2. Task 3.9: Extract _DialogoEdicionDispositivo to separate file (pantalla_ajustes.dart at 1450 lines is acceptable; extraction can be future refactor)
  3. Proposal Risk: nombresDispositivos not in export schema v4 (acknowledged, deferred per proposal)

Rollback Plan

All changes are additive:

  • Remove commit(s) → reverts all code and new SP key (eq_nombres_dispositivos_v1) is ignored
  • No data loss; backwards-compatible with prior state
  • Startup seeding is a single method call — removing it restores prior (broken) behavior

Testing Evidence

Build & Test Command:

flutter test
flutter analyze

Results:

  • flutter test: 231 tests ALL PASS ✓
  • flutter analyze: No issues found ✓

Coverage:

  • All 18 spec scenarios covered by tests ✓
  • CRITICAL-1 guard tested (2 tests for on/off toggle) ✓
  • CRITICAL-2 guardarPresetDispositivo tested (4 tests, device active & inactive) ✓
  • WARNING-2 locales (7 files, all keys present) ✓
  • WARNING-3 FakeServicio preservation (2 tests) ✓

Next Steps

None. The change is COMPLETE and CLOSED.

  • Implementation ready for production
  • All tests passing
  • Spec fully satisfied
  • No open CRITICALs or WARNINGs
  • 3 chained PRs merged to main
