TarjetaEmisora had the only good fallback for a station with no artwork --
a deterministic pick from 4 bundled illustrations with a gradient/glyph
last resort. FilaEmisoraPlana's flat rows, the Escuchar hero, the "Tus
emisoras" grid cell, the mini player and the full player each had their
own, separate, flat primaryContainer square instead.
Extract the good fallback into PluriStationArtFallback and use it from
every one of those call sites. The selection formula (asset order,
codeUnits-sum modulo) is preserved exactly, since navegacion_auto.dart
mirrors the same formula independently for Android Auto's own drawable
rotation.
Audit S7 plus the open items on screens 1-3. Escuchar gains the
prototype's own 52px "now listening" eyebrow header (t4:53), which is
structurally different from the 56px title row every other root uses
(t4:325) -- the earlier wiring test asserted PluriRootHeader on all five
roots, an over-broad premise now corrected to guard what actually holds:
no AppBar, and the sleep-timer action still reachable.
Tier 4 visual fidelity, audit 1.11/1.12 (t4 line 80): a pill badge next
to "Tus emisoras" now shows the TOTAL favorite count (not the 8-capped
grid size), and "Ver todas" is plain 12px/w800 brand-teal text instead
of a Material TextButton with its own padding and splash.
Item 1.4 (hero art radius) was already fixed as a side effect of an
earlier commit — no change needed here.
Audit 1.10 (t4 lines 82-88): the prototype shows a 2x2+ grid of 8
favorite stations; the build was a 260px-wide horizontal strip capped
at 6.
Raises the cap to 8 and replaces the horizontal ListView with a
GridView.builder (2 columns, gap 10). Adds a dedicated _CeldaTusEmisoras
cell (44px square art radius 11, name + genre) rather than reusing
TarjetaEmisora(esCompacta: true), since that widget always renders a
favorite button and a live badge that this prototype cell never draws.
Audit 1.7/2.5 (t4 lines 66-68, 120-122): the prototype draws 30
discrete bottom-anchored bars (radius 2, vertical gradient); the
build's VisualizadorAudio painted a single continuous oscilloscope
stroke, so its `barras: 30` parameter never produced bars.
Adds an opt-in `barrasDiscretas` mode (default false, byte-identical
continuous rendering preserved for any other caller) plus a
`gradienteFinAlpha` knob for the two screens' differing gradient
end-alpha (.3 vs .45). Wires it into the Escuchar hero and the full
player, correcting the player's bar count/height to match the
prototype (26->30 bars, 46->40px) at the same time.
Audit 1.6 (t4 line 62): the Escuchar hero never rendered "genre ·
country · bitrate kbps" between the station name and the visualizer.
Built from fields Emisora already carries (tags/pais/bitrate) — no
new fields, no service calls — omitting gracefully whatever a station
lacks.
Audit 1.3: the hero art shipped at 84 where the prototype draws 132
(t4 line 56), with a 24 corner radius rather than the shared radiusMd.
Adds a dimension guard. Every existing test on this screen asserts
behaviour only, which is why an artwork 36% too small went unnoticed.
Restructures PantallaInicio's top of screen: a new _EscucharHero
(square art, live/offline pill, VisualizadorAudio at barras: 30 /
altura: 26 / color: liveGreen, a 5-action transport row - favorite,
EQ toggle, stop, play/pause, sleep - plus a tool-tray entry chip
opening the full player) replaces the old PluriScreenHeader hero, and
a new "Tus emisoras" section (favorites preview, capped, "Ver todas")
follows it. Per design ADR-7, EstadoRadio stays the single source of
truth: the hero is a StatelessWidget with no cached fields, reading
emisoraActual via context.select (uuid-based equality scopes rebuilds
to real station changes) and the fast-changing playback status via
StreamBuilder, the same pattern _Controles/MiniReproductor already
use. The still-present discovery sections (_seccionCercanas onward,
including the old grid) are deliberately left in place - WU6
relocates them to Buscar and deletes them from here; removing them
now would leave that content nowhere until WU6 lands.
MiniReproductor gains a `visible` parameter (default true) and a
measured `static const double altura`. app.dart passes
`visible: indice != RaizPluriWave.escuchar.index`, hiding it visually
only (SizedBox.shrink()) while Escuchar is active, since the hero
already shows the same station - the State stays mounted so its
didChangeDependencies side effect (configurarLocalizaciones, S3-R3)
keeps running regardless of tab. altura was measured empirically
(72.0, via tester.getSize) rather than guessed, backing a new derived
PluriLayout.escucharBottomChromeInset constant now wired into
PantallaInicio's own bottom padding.
"Ver todas" switches roots via EstadoNavegacionRaiz.irA(favoritos),
verified via a NavigatorObserver asserting the push count is
unchanged (switches tabs, does not push).
Fixed a pre-existing test-infrastructure gap while writing the
anti-cache test: no test in this codebase had ever exercised
ServicioAudio.androidAudioSessionIdStream against a bare
FakeServicioAudio (pantalla_reproductor.dart has always read it but
has no test file at all) - the real getter needs registrarHandler()
(main.dart, production only) and threw otherwise. Added an empty
stream override to FakeServicioAudio, matching VisualizadorAudio's
own documented no-native-session fallback.
Tests: 614 -> 618 (2 skipped, unchanged). flutter analyze unchanged
at 1 pre-existing info. git diff empty for visualizador_audio.dart
and estado_radio.dart - this WU touches neither.
- New EstadoGrabacion owns the recording service, subscription, directory/size preferences and open-file actions
- New EstadoBusqueda owns search, nearby stations, pagination and the min-bitrate filter
- New orden_emisoras.dart with the OrdenEmisoras enum, shared sorter and list identity memoization so context.select comparisons work on derived lists
- Large screens (inicio, buscar, favoritos, ajustes, reproductor) consume scoped selects/dedicated notifiers instead of root context.watch<EstadoRadio>, so audio buffer events no longer rebuild whole screens
- Remove all 15 TODO(S4b) compat members from EstadoRadio; consumers use the dedicated providers. EstadoRadio drops from ~1121 to 753 lines, keeping playback/stations/favorites orchestration
- 8 new tests including a rebuild-scoping probe (110 total green), flutter analyze clean
- Added state management for startup retry and custom station handling in `EstadoRadio`.
- Created tasks for implementing strict TDD with RED tests for HTTP failure retries and EQ persistence.
- Developed verification report to ensure compliance with TDD practices.
- Introduced fake services for testing, including `FakeServicioAudio`, `FakeServicioFavoritos`, and `FakeServicioRadio`.
- Implemented widget tests for `PantallaInicio` and `PantallaFavoritos` to validate UI behavior with custom stations.
- Enhanced `ServicioRadio` to support host rotation and retry logic for API calls.
- Established a new configuration file to enforce project constraints and testing rules.
