Patch release — hotfix for Google Sign-In broken in 2.0.0.
### Fixed
- **Sign in with Google** (`lib/screens/login_screen.dart`): Resolved authentication failure introduced in 2.0.0. Google OAuth flow now completes correctly and exchanges tokens with Django `POST /accounts/google-auth/` as expected.

## [2.0.0] - 2026-04-10
Public release milestone. Full backend integration, real image upload pipeline, complete personal profile system, and production Android build infrastructure.
- **Real image upload pipeline** (`lib/core/api/api_client.dart`): `uploadFile()` method uses `http.MultipartRequest` with explicit MIME type detection from file extension. Supports JPEG, PNG, WebP, MP4, MOV. Files upload to Node.js `/api/v1/upload/file` → OneDrive via Microsoft Graph API, returning a shareable anonymous link.
- **Contribute image upload to OneDrive** (`lib/features/gamification/services/gamification_service.dart`): `submitContribution()` now uploads all selected images before submitting the event form. Uploaded file metadata (including OneDrive share URL) is passed as `media` array in the contribution payload — replacing the broken device-path-as-string approach.
- **Upload endpoint constant** (`lib/core/api/api_endpoints.dart`): `ApiEndpoints.uploadFile` pointing to `$_nodeBase/v1/upload/file`.
- **Full personal info form in Edit Profile sheet** (`lib/screens/profile_screen.dart`):
- First Name, Last Name fields
- Email (read-only, locked from direct edit)
- Phone number field
- District picker with 183-day change cooldown — shows next-change date when locked
- Place, Pincode, State, Country fields
- All fields loaded from SharedPreferences cache and API on open; saved via `PATCH /api/user/update-profile/`
- **Android build version override** (`android/app/build.gradle.kts`): Removed hardcoded `versionCode = 17` and `versionName = "1.6.1(p)"` — both now read from `flutter.versionCode` / `flutter.versionName` (sourced from `pubspec.yaml`). This was causing Play Store rejections ("version code 17 already used") on every release build.
- **`http_parser` dependency added** (`pubspec.yaml`): Required for explicit `MediaType` MIME typing in `MultipartRequest`. Without it, file uploads defaulted to `application/octet-stream` and were rejected by the Node.js multer middleware.
### Infrastructure
- **Production AAB built and signed** with `upload-keystore-new.jks` — build 20, version name `2.0` — submitted to Google Play Console.
- **`build.gradle.kts` signing config** reads `KEYSTORE_PASSWORD`, `KEY_ALIAS`, `KEY_PASSWORD` from `gradle.properties` or environment variables (no secrets in source).
Phase 4 — animation polish and final feature gaps. Flutter app reaches full feature parity with Consumer Web App v1.4.9.
### Added
- **BouncingLoader widget** (`lib/widgets/bouncing_loader.dart`): 3-dot bouncing animation with staggered 200 ms delays using `Curves.bounceOut`. Replaces `CircularProgressIndicator` in home, contribute, and review screens. Accepts `color`, `dotSize`, and `spacing` parameters.
- **DiceBear Notionists avatars on review cards** (REV-001): `CachedNetworkImage` fetches `api.dicebear.com/9.x/notionists/svg?seed={username}`. Falls back to coloured initial letter `CircleAvatar` on error or while loading.
- **Server-side event search** (HOME-007): Search modal now sends `q` param to `EventsByPincodeView`; client-side filter stays for instant `onChanged` feedback while server results load on submit. Cache is bypassed for search queries. Django backend updated with `Q(title__icontains=q) | Q(description__icontains=q)` OR filter.
- **`flutter_staggered_animations: ^1.1.1`** added to pubspec.
### Changed
- **Review list stagger animation** (REV-003): `AnimationLimiter` + `AnimationConfiguration.toStaggeredList` wraps review cards with 375 ms slide-up + fade-in per item.
- **Review submit success spring animation** (REV-004): Checkmark icon now animates with `ScaleTransition` driven by `Curves.elasticOut` (600 ms) instead of a static icon swap.
- **Hero transitions on event cards** (UX-005): `Hero(tag: 'event-hero-{id}')` wraps event images in home screen and matching destination in learn more screen — enabling shared-element transitions.
- **FadeTransition on learn more screen** (UX-005): Screen body fades in with `Curves.easeIn` (350 ms) after event data loads.
- **AnimatedList stagger on leaderboard** (UX-005): `SliverList` entries animate with `AnimationConfiguration.staggeredList` — 375 ms slide-up + fade-in per row.

- **Skeleton loading with shimmer** (UX-001): `shimmer: ^3.0.0` added; event feed, leaderboard, and profile screens show shimmer placeholders while data loads.
- **Contributor stats real API** (CTR-001): EP/RP balance and tier fetched from Node.js gamification endpoint on dashboard load.
- **Achievement progress tracking** (ACH-001): Progress bars and completion state fetched from API; local mock removed.
- **Profile stats row** (PROF-003): Likes / Posts / Views counts fetched from user profile API and displayed in profile header.
### Changed

- **District filter on leaderboard** (LDR-002): Leaderboard district pills populated from API; selecting filters rank table in real time.
