+## PlayMaker — guidance for AI coding assistants
+
+This file gives focused, actionable knowledge to quickly make safe edits in the PlayMaker Flutter app.
+
+Key facts (big picture)
+- App: Flutter (mobile + desktop) using Supabase for backend and SharedPreferences for local persistence.
+- Data ownership: teams are per-user (teams.user_id). Team records include fields like `id`, `name`, `image_url`, `wins`, `losses`, `draws`, `is_favorite`.
+- Global selection: the app exposes a single global active team via `lib/controllers/active_team.dart` — a `ValueNotifier<ActiveTeam?>` named `globalActiveTeam`. Use `loadGlobalTeam()` and `saveGlobalTeam()` to read/update both local (SharedPreferences) and Supabase (`profiles.selected_team_id`).
+
+Where to look (important files)
+- `lib/controllers/active_team.dart` — central logic: load/save active team, prefers favorite team after our recent change.
+- `lib/controllers/team_controller.dart` — creates teams, toggles favorites and exposes `teamsStream` for realtime listing.
+- `lib/pages/home.dart` — main UI that shows the selected team, reads/writes last_team_* prefs and uses `TeamController` streams.
+- `lib/pages/status_page.dart` — shows detailed stats and accepts initialTeam* props; will use the same persistence keys as `home.dart` as a fallback.
+- `lib/widgets/*.dart` — UI building blocks (game, placar, team widgets) that assume team names/logos are strings and use `globalActiveTeam`/selectedTeam state.
+
+Project-specific conventions & patterns
+- Single active team: stored locally under prefs keys `last_team_id`, `last_team_name`, `last_team_logo`, `last_team_wins`, `last_team_losses`, `last_team_draws`.
+- Realtime lists: controllers expose Streams from Supabase (e.g., `teamsStream`) and UI uses `StreamBuilder`/`snapshot.data` expecting List<Map<String,dynamic>>.
+- Favoriting: `teams.is_favorite` is a boolean; code expects at most one favorite per user. When marking favorite, clear other favorites for that user and set the favorite as the global active team (we updated `team_controller.toggleFavorite` to do this).
+- Global state: prefer using `globalActiveTeam` instead of ad-hoc SharedPreferences reads when changing the current team — it notifies Home and Status pages automatically.
+- Naming: Portuguese UI strings are used throughout (e.g., "Selecionar Equipa"), so preserve that when editing visible text.
+
+Examples of common edits
+- Changing how the active team is chosen: edit `loadGlobalTeam()` in `lib/controllers/active_team.dart`. Example behaviour implemented: prefer `teams.is_favorite == true`, then fallback to `profiles.selected_team_id`, then local prefs.
+- Adding a field to teams: update Supabase schema, then adapt `TeamController.getTeamsWithStats()` and UI widgets under `lib/widgets/` to read the new field.
+- Making UI reactive to team changes: call `saveGlobalTeam(ActiveTeam(...))` to update memory, Supabase profile and notify UI.
+
+Developer workflows (how to build/test/debug)
+- Install dependencies: `flutter pub get`.
+- Run on iOS simulator: `flutter run -d ios` (macOS only). Android: `flutter run -d android`.
+- Quick analyzer: `flutter analyze` or rely on the project's editor diagnostics.
+- Running tests: There is a `test/widget_test.dart` — run `flutter test` to execute.
+- When debugging Supabase flows locally, ensure `google-services.json` (Android) and iOS config files are present under `android/app/` and `ios/` as appropriate.
+
+Safe-edit checklist for AI agents
+- Prefer small, focused patches. Keep existing structure and naming conventions (Portuguese strings, `prefs` keys and Supabase table names).
+- When touching team selection: update both local prefs and Supabase `profiles.selected_team_id` (use `saveGlobalTeam`).
+- When changing persistence keys, update both `home.dart` and `status_page.dart` and `active_team.dart`.
+- Avoid altering app-wide themes or widget contracts unless necessary; many widgets rely on team names/logos being non-null strings.
+- If adding Supabase queries, filter by `user_id` unless deliberately global.
+
+If you can't find something
+- Search for the pref keys `last_team_id` / `last_team_name` / `last_team_logo` to locate all usages.
+- Look for `globalActiveTeam` to see places that react to the active team.
+
+Contact / next steps
+- After applying changes that affect team selection flow, run `flutter analyze` and (if possible) `flutter test`.
+- Ask for confirmation before changing user-visible Portuguese copy or database schema.

+# Resumo das Mudanças - Sincronização de Jogo em Tempo Real
+
+## 1. lib/controllers/placar_controller.dart
+
+### Adicionado ao constructor:
+```dart
+final void Function(String actionType, Map<String, dynamic> actionData)? onSyncAction;
+
+PlacarController({
+  required this.gameId,
+  required this.myTeam,
+  required this.opponentTeam,
+  this.onSyncAction,  // ← NOVO
+});
+```
+
+### Adicionado método _dispatchSyncAction:
+```dart
+void _dispatchSyncAction(String actionType, Map<String, dynamic> actionData) {
+  if (onSyncAction != null) {
+    final enrichedActionData = Map<String, dynamic>.from(actionData)
+      ..['remaining_seconds'] = durationNotifier.value.inSeconds
+      ..['is_running'] = isRunning;
+    onSyncAction!(actionType, enrichedActionData);
+  }
+}
+```
+
+### Adicionado em 5 métodos (chamada _dispatchSyncAction):
+- `useTimeout()` → dispatch `'use_timeout'`
+- `handleSubbing()` → dispatch `'subbing'`
+- `swapCourtPlayers()` → dispatch `'swap_players'`
+- `registerFoul()` → dispatch `'register_foul'`
+- `commitStat()` → dispatch `'commit_stat'`
+
+**Exemplo em commitStat:**
+```dart
+_dispatchSyncAction('commit_stat', {
+  'action': action,
+  'player_data': playerData,
+});
+```
+
+---
+
+## 2. lib/pages/PlacarPage.dart
+
+### Adicionado ao state:
+```dart
+String? _lastAppliedSyncEventId;  // ← NOVO - deduplicação de eventos
+```
+
+### Constructor do controller:
+```dart
+_controller = PlacarController(
+  gameId: widget.gameId,
+  myTeam: widget.myTeam,
+  opponentTeam: widget.opponentTeam,
+  onSyncAction: _onLocalControllerSync,  // ← CONECTADO
+);
+```
+
+### Adicionado novo método _onLocalControllerSync:
+```dart
+void _onLocalControllerSync(String actionType, Map<String, dynamic> actionData) {
+  if (_sessionId == null || _isApplyingRemoteSync) return;
+  print("📤 Enviando sync action local: $actionType -> $actionData");
+  _sharingController.sendSyncEvent(_sessionId!, actionType, actionData);
+}
+```
+
+### Atualizado _setupSyncListener (deduplicação):
+```dart
+_syncSubscription = _sharingController.listenToGameSyncOthers(_sessionId!).listen(
+  (dynamic event) {
+    Map<String, dynamic>? record;
+    if (event is List && event.isNotEmpty) {
+      for (final item in event) {
+        final row = item as Map<String, dynamic>?;
+        if (row == null) continue;
+        final rowId = row['id']?.toString();
+        if (rowId != null && rowId != _lastAppliedSyncEventId) {
+          record = row;
+          break;  // ← para no primeiro evento novo
+        }
+      }
+    } else if (event is Map<String, dynamic>) {
+      record = Map<String, dynamic>.from(event);
+    }
+
+    if (record != null) {
+      final recordId = record['id']?.toString();
+      if (recordId != null && recordId == _lastAppliedSyncEventId) return;
+      if (recordId != null) _lastAppliedSyncEventId = recordId;
+      _applyRemoteSyncEvent(record);
+    }
+  },
+);
+```
+
+### Atualizado _applyRemoteSyncEvent (aplicar estado remoto):
+```dart
+void _applyRemoteSyncEvent(Map<String, dynamic> record) {
+  final actionType = record['action_type']?.toString();
+  final actionData = Map<String, dynamic>.from(record['action_data'] ?? {});
+
+  // ← NOVO: aplicar timer remotamente em TODAS as ações
+  final remoteSeconds = int.tryParse(actionData['remaining_seconds']?.toString() ?? '');
+  final remoteIsRunning = actionData['is_running'] == true;
+  if (remoteSeconds != null) {
+    _controller.durationNotifier.value = Duration(seconds: remoteSeconds);
+  }
+  if (remoteIsRunning != _controller.isRunning) {
+    _isApplyingRemoteSync = true;
+    _controller.toggleTimer(context);
+    _isApplyingRemoteSync = false;
+  }
+
+  // Aplicar ações específicas
+  if (actionType == 'toggle_timer') {
+    setState(() {});
+  } else if (actionType == 'commit_stat') {
+    // aplicar pontos/faltas
+  } else if (actionType == 'register_foul') {
+    // aplicar falta
+  } else if (actionType == 'subbing') {
+    // aplicar substituição
+  } else if (actionType == 'swap_players') {
+    // trocar posição
+  } else if (actionType == 'use_timeout') {
+    // usar timeout
+  }
+}
+```
+
+---
+
+## Fluxo Completo
+
+1. **Ação Local** → `commitStat()` no controller
+2. **Controller emite** → `_dispatchSyncAction('commit_stat', {action, player_data, remaining_seconds, is_running})`
+3. **PlacarPage escuta** → `_onLocalControllerSync()` recebe o evento
+4. **Envia ao Supabase** → `sendSyncEvent()` armazena em `game_sync_events`
+5. **Parceiro recebe** → `listenToGameSyncOthers()` retorna o evento
+6. **Aplica remotamente** → `_applyRemoteSyncEvent()` executa a ação no parceiro
+7. **Estado sincronizado** → Ambos têm timer, pontos, faltas idênticos
+
+---
+
+## Resultado
+
+✅ Timer não reseta ao marcar ponto
+✅ Pontos sincronizam entre os dois lados
+✅ Faltas sincronizam
+✅ Timeouts sincronizam
+✅ Substituições sincronizam
+✅ Posições de jogadores sincronizam
