+# Dark Mode Audit Checklist (Mobile)
+
+본 문서는 Flutter 앱의 다크 모드 대비(가독성/명암비/아이콘 가시성)를 점검하기 위한 실기 체크리스트입니다. 점검 결과에 따라 팔레트 미세 보정 또는 위젯 레벨 스타일 수정을 권장합니다.
+
+## 점검 범위
+- 화면: `events_screen.dart`, `event_details_screen.dart`, `event_form_screen.dart`, `members_screen.dart`, `member_statistics_screen.dart`, `dashboard_screen.dart`, `club_settings_screen.dart`
+- 공통 컴포넌트: `theme/badges.dart`, `widgets/dialog_actions.dart`, Chip/Button/Card/Input/SnackBar/Tooltip
+
+## 공통 체크 항목
+- [ ] 배경/전경 색상 대비가 충분한가 (텍스트/아이콘 최소 4.5:1 권장)
+- [ ] 텍스트가 배경색과 혼동되지 않는가 (세컨더리/보조 텍스트 포함)
+- [ ] 아이콘 색이 배경과 충분히 구분되는가 (특히 회색 계열)
+- [ ] 링크/버튼/상태 배지의 의미가 색만으로 전달되지 않는가 (아이콘/레이블 병행)
+- [ ] elevation/shadow가 다크 모드에서 과도하거나 부족하지 않은가
+- [ ] 오버레이(다이얼로그/바텀시트/팝업) 배경과 콘텐츠 대비가 적절한가
+- [ ] focus/hover/pressed 상태의 컬러가 다크 모드에서도 인지 가능한가
+
+## 위젯별 체크 항목
+- Buttons (Elevated/Outlined/Text)
+  - [ ] foreground/background/disabled 상태 대비
+  - [ ] OutlinedButton의 border 대비 (다크 테마 기준)
+- Chips/FilterChip
+  - [ ] 선택/비선택 상태의 labelColor/backgroundColor 대비
+- Cards/ListTiles
+  - [ ] 카드 배경/경계/섀도우 과도 여부
+  - [ ] 타이틀/서브타이틀 텍스트 대비 (`overflow: TextOverflow.ellipsis` 유지)
+- Inputs/TextFields
+  - [ ] label/hint/helper/error 컬러 대비 및 가독성
+  - [ ] prefix/suffix 아이콘 대비
+- SnackBars/Tooltips
+  - [ ] 텍스트/아이콘 대비, action 버튼 가독성
+- Badges (`theme/badges.dart`)
+  - [ ] 자동 전경색 선택 로직이 다크 모드에서도 적절한가
+  - [ ] 상태(활성/대기/취소/완료, 회원유형/참가상태/결제상태) 배지 대비 검증
+
+## 화면별 포인트
+- EventsScreen
+  - [ ] 카드 타이틀/위치 ellipsis 유지 + 대비 확인
+  - [ ] 상태 배지 대비/간격/줄바꿈(Wrap) 확인
+- EventDetailsScreen
+  - [ ] 기본정보 섹션 텍스트/아이콘 대비
+  - [ ] 탭/탭바/콘텐츠 배경 대비
+- EventFormScreen
+  - [ ] 필수/보조 텍스트 컬러 대비 (실시간 유효성 스타일 포함)
+  - [ ] 공개 접근 섹션(공개 URL/비밀번호) 라벨/아이콘 대비
+- Members/Metrics/Dashboard/Settings
+  - [ ] 배지/보조 텍스트/아이콘 전반 대비 확인
+
+## 수행 절차(권장)
+1) iOS 시뮬레이터에서 라이트/다크 전환 후 각 화면을 순회 점검
+2) 스크린샷 취득 및 문제 구간 표시
+3) 빠른 보정은 테마의 `colorScheme` 튜닝 또는 `BadgeStyles` 전경 색상 보정으로 처리
+4) 복잡한 케이스는 위젯 로컬 스타일 적용 (ex. `Theme.of(context).brightness` 분기)
+
+## 보정 가이드
+- Material 3 ColorScheme 다크 프리셋을 기본으로 사용
+- 배지 전경색: 배경 대비를 계산해 흰/검정 중 대비가 큰 색을 선택 (`theme/badges.dart` 참고)
+- 회색 글자: 다크 모드에서는 명도 차이를 더 키워 가독성 확보
+
+## 결과 기록 템플릿
+```
+화면: events_screen.dart
+- 카드 타이틀/서브: OK
+- 상태 배지: 대기 상태 배지 전경 대비 부족 → BadgeStyles.eventStatus 대기 색상 전경색 보정 필요
+- 파일 업로드 다이얼로그: OK
+```
+
+## 현장 점검 기록 (2025-09-10T07:43:19+09:00 시작)
+- 대상 화면
+  - [ ] `lib/screens/club/events_screen.dart`
+  - [ ] `lib/screens/club/event_details_screen.dart`
+  - [ ] `lib/screens/club/event_form_screen.dart`
+
+- 초기 관찰(1차)
+  - events_screen.dart
+    - 카드 타이틀/서브: 대비 양호(OK)
+    - 상태 배지: 일부 회색 배경의 전경 대비 약함 → BadgeStyles.eventStatus 전경색 계산 재검토 필요
+    - 카드 쉐도우: 다크에서 살짝 강함 → elevation 단계 -1 검토
+  - event_details_screen.dart
+    - 섹션 타이틀/아이콘: 대비 양호(OK)
+    - 탭바/선택 배경: 대비 양호(OK)
+    - 보조 텍스트(secondary): 명도 부족 구간 존재 → Typography.secondary 톤 상향 검토
+  - event_form_screen.dart
+    - TextField label/hint: 대비 양호(OK)
+    - prefix/suffix 아이콘: 일부 아이콘 대비 약함 → IconTheme 다크 톤 상향 검토
+    - OutlinedButton border: 배경과의 대비 약함 → 테마의 outline 색상 톤 업 필요
+
+ 개선 후보(누적)
+  - [ ] `lib/theme/badges.dart`: 배지 전경 대비 계산 로직 검토(다크 모드에서 회색계 배경 대비 강화)
+  - [ ] `SnackBar` action 텍스트 대비 확인 및 필요 시 컬러 보정
+  - [ ] 보조 텍스트(secondary) 명도 상향 검토
+  - [ ] OutlinedButton 다크 테마 border 색상 톤 업
+  - [ ] IconTheme(다크) 기본 톤 상향으로 prefix/suffix 대비 강화
+  - [ ] 카드 elevation 다크 모드 단계 -1 검토

+# PrimeVue 유사 디자인 가이드 (적용 준비 문서)
+---
+
+## 목표
+- PrimeVue의 Badge/Tag, Dialog, DataTable, Toolbar, Button 스타일 특징을 분석하여 Flutter 머티리얼 디자인에 이식 가능한 규칙 수립
+- 앱 전반의 시각적 일관성 및 사용성 향상
+
+## 핵심 포인트 요약
+- 색상 계층: Primary/Success/Warning/Danger + Soft Background 톤 병행
+- 아이콘+텍스트 조합, Pill 형태의 배지, 여백 8px 단위 그리드
+- 테이블 밀도 조절, 헤더 강조, 정렬/필터 affordance 명확화
+- 다이얼로그 버튼 정렬, 파괴적 액션 시각 구분
+
+## Flutter 적용 원칙
+- Material 3 스펙을 기본으로, 색상/여백만 PrimeVue 유사 톤으로 튜닝
+- 공통 위젯(배지, 다이얼로그 액션, 테이블 래퍼)로 재사용성 확보
+
+## 컴포넌트 매핑
+- Badge/Tag → Chip
+- Dialog → AlertDialog/BottomSheet
+- DataTable → DataTable/PaginatedDataTable(또는 community DataTable2)
+- Toolbar → AppBar/SliverAppBar + Actions
+- Button → Elevated/Outlined/Text
+
+## 체크리스트
+- [x] 배지 스타일 클래스 설계 및 적용 시작(`BadgeStyles`)
+- [ ] 다이얼로그 액션 유틸 설계(`DialogActions`)
+- [ ] 데이터 테이블 래퍼 설계
+- [ ] 프리뷰 스크린/스토리북 추가
+
+## 다음 단계
+1) DialogActions 유틸 구현 및 2개 화면에 시범 적용
+2) 데이터 테이블 래퍼 설계 초안 작성 및 샘플 테이블 구현
+3) UI Preview 스크린에 샘플 컴포넌트 카탈로그 구성

+# Flutter UI 스타일링 초안 (Material 3 기반)
+---
+
+## 목적
+- Flutter 앱에서 배지/다이얼로그/데이터테이블 등 핵심 UI 컴포넌트의 일관된 스타일 가이드를 수립한다.
+- Flutter Material 3 디자인을 기본으로, 앱의 브랜드 톤에 맞게 경량 튜닝한다.
+
+## 공통 디자인 원칙
+- 그림자/여백: Card, Dialog, Menu에 적절한 elevation(1~4)과 8~16px 패딩 적용
+- 컬러 시스템: Primary(Blue 600/700), Success(Green 600), Warning(Amber 600), Danger(Red 600)
+- 라운딩: 기본 8px, Badge(12px), 버튼 Pill 옵션은 상황별 적용
+- 접근성: 대비비(AA) 확보, 의미색 + 아이콘 병행
+
+## 배지(Badge)
+- 형태: Chip + 아이콘 + 텍스트
+- 높이: 24~28
+- 색상 매핑 예시
+  - 회원유형: {정회원=Blue 100, 준회원=Indigo 100, 게스트=Grey 200}
+  - 참가상태: {등록됨=Grey 200, 확인됨=Green 100, 취소됨=Red 100, 참석함=Blue 100}
+  - 결제상태: {미결제=Red 100, 결제완료=Green 100}
+- 아이콘 매핑 예시
+  - 정회원=person, 준회원=person_outline, 게스트=person_add_alt
+  - 등록됨=how_to_reg, 확인됨=check_circle, 취소됨=cancel, 참석함=event_available
+  - 미결제=cancel, 결제완료=check_circle
+
+## 다이얼로그(Dialog)
+- AppBar 없는 AlertDialog/BottomSheet 권장
+- 타이틀은 18~20, 본문은 14~16
+- 버튼 영역 Right-aligned, 기본/파괴적 버튼 구분
+- 하단 액션: TextButton(취소)/ElevatedButton(확인)
+
+## 데이터 테이블(DataTable)
+- 밀도(dense) 모드: 행 높이 44~48
+- 정렬 화살표, 고정 폭 컬럼 최소화, 긴 텍스트 ellipsis + Tooltip
+- 헤더 강조(반투명 배경), zebra striping(선택)
+
+## 적용 우선순위
+1) Badge 컴포넌트 공통화: `_buildBadge(text, color, icon)` 유지 + 색상/아이콘 매핑 상수화
+2) Dialog 일관화: 확인/취소 액션 정렬, 파괴적 액션 색상 구분
+3) 리스트 아이템 overflow 방지: `Row` → `Wrap/Flexible` 전환 규칙 정립
+4) 표형 데이터: `PaginatedDataTable`/`DataTable2` 검토 및 공통 위젯 래퍼 도입
+
+## 구현 체크리스트
+- [ ] `_buildBadge` 색상/아이콘 매핑 상수 분리(`lib/theme/badges.dart`)
+- [ ] 다이얼로그 액션 빌더 유틸(`lib/widgets/dialog_actions.dart`)
+- [ ] 리스트 아이템 텍스트/뱃지 Wrap 적용 가이드(`docs/guides/list_wrap_rules.md`)
+- [ ] 데이터 테이블 공용 래퍼(`lib/widgets/data_table_wrappers.dart`)
+- [ ] 샘플 스크린/스토리북(`lib/screens/dev/ui_preview_screen.dart`)
+
+## 참고
+- Material 3 디자인 가이드
+- (선택) 타 UI 라이브러리에서 유용한 패턴이 있을 경우 제한적으로 참고

+# Test Utilities Guide
+
+본 문서는 Flutter 위젯/서비스 테스트를 안정적으로 작성하기 위한 공용 유틸 사용 가이드를 제공합니다. 실제 예시는 프로젝트 내 테스트 코드에서 그대로 복사해 사용할 수 있습니다.
+
+## 구성 요소
+
+- test/utils/mock_services.dart
+- test/utils/stub_event_service.dart
+- test/utils/provider_presets.dart
+- test/utils/widget_test_utils.dart (향후 확장 시)
+- test/utils/event_bus_test_utils.dart
+
+## 공통 패턴
+
+- __오버레이/네비 의존 제거__: 팝업/스낵바/네비게이션은 테스트에서 `pumpAndSettle`를 가로막는 대표 원인입니다. 가능하면 화면에 `@visibleForTesting` 훅(예: `invokeSaveForTest`, `invokeDuplicateForTest`)을 제공하여 내부 로직을 직접 호출하세요.
+- __pumpAndSettle 지양__: 무한 대기 가능성이 있으므로, `await tester.pump()` + `await tester.pump(const Duration(milliseconds: 50))` 조합을 우선적으로 사용합니다.
+- __ensureVisible__: 탭/토글/입력 전에는 `await tester.ensureVisible(finder)`로 화면 내 가시성을 보장합니다.
+- __Key 부여__: 테스트가 찾는 주요 위젯에는 `ValueKey`를 부여합니다. 예) `ValueKey('access_password_field')`, `ValueKey('event_menu_<id>')`.
+- __SharedPreferences 모킹__: 영속 값(검색어 등)을 사용 시 `SharedPreferences.setMockInitialValues({...})`를 통해 초기 상태를 정의합니다.
+
+## Mock/Stub 소개
+
+### MockAuthService / MockClubService (`test/utils/mock_services.dart`)
+- __MockAuthService__
+  - 고정 토큰과 사용자 정보(`User`)를 제공합니다.
+  - `isAuthenticated`, `currentUser`, `token` 등을 간단히 반환합니다.
+- __MockClubService__
+  - 단일 `Club`을 보유하고 `currentClub`/`clubs`를 제공합니다.
+  - `updateClub()`는 `ownerId` 반영 정도만 최소 구현했습니다.
+
+사용 예시:
+```dart
+final auth = MockAuthService(
+  user: User(id: 'u1', email: 'u@ex.com', name: 'Tester', role: 'owner'),
+  tokenValue: 'token',
+);
+final club = MockClubService(
+  club: Club(id: 'club1', name: '클럽', averageCalculationPeriod: '3'),
+);
+```
+
+### StubEventService (`test/utils/stub_event_service.dart`)
+- 네트워크 호출을 모두 차단하고 즉시 완료되는 `EventService` 대체 구현입니다.
+- __관찰 필드__
+  - `lastCloneCalled`, `lastClonedEventId`, `lastCreatedEventData`
+- __시드 이벤트__
+  - `seededEvents`에 `Event` 리스트를 주입해 목록을 렌더링합니다.
+- __안정화 포인트__
+  - `createEvent/cloneEvent`는 notifyListeners 후 바로 반환합니다.
+
+사용 예시:
+```dart
+final stub = StubEventService();
+await stub.initialize('token');
+stub.setClubId('club1');
+stub.seededEvents = [Event(id: 'e1', clubId: 'club1', title: '타이틀', startDate: DateTime.now(), status: '활성', isActive: true)];
+```
+
+### Provider 프리셋 (`test/utils/provider_presets.dart`)
+- 특정 화면에 필요한 Provider 집합을 손쉽게 구성합니다.
+- 현재 예시는 ClubSettings 시나리오용으로 제공되며, 필요 시 확장하세요.
+
+사용 예시:
+```dart
+MultiProvider(
+  providers: [
+    ChangeNotifierProvider<AuthService>.value(value: auth),
+    ChangeNotifierProvider<ClubService>.value(value: club),
+    ChangeNotifierProvider<EventService>.value(value: stub),
+  ],
+  child: const MaterialApp(home: EventsScreen()),
+);
+```
+
+## 화면별 테스트 팁
+
+### EventsScreen
+- __복제 메뉴 테스트__: `PopupMenuButton` 오버레이를 열지 말고, 상태 훅 `invokeDuplicateForTest(event)`를 호출하세요.
+- __ellipsis 회귀 테스트__: `Text` 위젯을 `find.textContaining()`으로 찾고, `Text.maxLines`/`Text.overflow`를 직접 검증하세요.
+
+### EventFormScreen
+- __저장 테스트__: 저장 버튼 탭 대신 `invokeSaveForTest()` 호출. 테스트 모드에서는 pop/스낵바를 우회하고 `_isLoading`을 해제하는 로직이 포함되어 있어 hang 방지에 유리합니다.
+- __비밀번호 필드__: `ValueKey('access_password_field')`로 필드 접근, 토글 아이콘은 `Tooltip('비밀번호 표시')`/`('비밀번호 숨김')`으로 찾습니다.
+
+## EventBus 테스트 유틸 (`test/utils/event_bus_test_utils.dart`)
+- 각 테스트에서 고유 테스트 ID를 설정하고, setUp/tearDown에서 `EventBus`를 초기화/해제합니다.
+- 간헐적 경합을 줄이기 위해 tearDown에서 짧은 대기(`Future.delayed`)를 추가합니다.
+
+샘플 패턴:
+```dart
+setUp(() async {
+  final testId = 'member_service_test_${DateTime.now().millisecondsSinceEpoch}';
+  await EventBusTestUtils.setUp(testId);
+});
+
+tearDown(() async {
+  await EventBusTestUtils.tearDown();
+  await Future<void>.delayed(const Duration(milliseconds: 100));
+});
+```
+
+## 권장 사항 요약
+
+- __핵심__: 오버레이/네비 의존 제거, 테스트 훅 사용, `pumpAndSettle` 지양.
+- __상태__: `_isLoading`은 성공/실패 모두 해제되도록 보장.
+- __가시성__: 액션 전 `ensureVisible` 사용.
+- __모델/타입__: 실제 모델 시그니처에 맞는 파라미터(문자열/정수, const 사용 여부 등) 확인.
