…olicies Adds the DB/storage foundation for profile avatar upload (issue 102): - avatar_url TEXT column on users, nullable, populated after upload. - Public avatars Storage bucket (public read, since profile pictures are non-sensitive and need to render everywhere in the app without signed URLs). - RLS policies on storage.objects scoped to the avatars bucket: public SELECT, and INSERT/UPDATE/DELETE restricted to the authenticated owner via (storage.foldername(name))[1] = auth.uid()::text, i.e. the object path convention is <user_id>/<filename> within the bucket. Flutter-side image picker and upload UI are a separate follow-up. Signed-off-by: g-k-s-03
Adds uploadAvatar(File) and removeAvatar() to SupabaseService, plus the
image_picker dependency, as the service-layer half of profile avatar
support (issue 102). No UI or shared-state changes yet -- those are
separate follow-up steps.
uploadAvatar uploads to a fixed '<user_id>/avatar.jpg' storage path
with upsert: true (overwriting any previous avatar rather than
accumulating orphaned files), matching the path convention documented
in supabase/migrations/20251021110000_avatar_url_and_storage.sql, then
writes the resulting public URL to avatar_url via the existing
updateUserProfile helper so the profile cache stays in sync.
removeAvatar deletes the same storage object and clears avatar_url,
tolerating a missing storage object (e.g. user never uploaded one) as
long as the profile update itself succeeds.
Both follow the existing {'success': bool, 'error': ...} return
convention used throughout this file.
pub get / pub upgrade still needs to be run locally to fetch the new
image_picker dependency -- not run here.

Adds UserProfileController (lib/providers/user_profile_provider.dart), a ChangeNotifier holding the current user's profile as shared, reactive app state, modeled directly on the existing ThemeController / themeControllerProvider pattern in lib/providers/theme_provider.dart. refresh() loads/reloads the profile via SupabaseService's existing getCurrentUserProfile(), and updateAvatarUrl() lets the Edit Profile screen push a new avatar_url into shared state right after a successful uploadAvatar()/removeAvatar() call, without a full refetch, so every screen holding a reference to the controller re-renders immediately. Registered in lib/main.dart alongside ThemeController: overridden in the Riverpod ProviderScope and exposed via the provider package through a MultiProvider (replacing the single ChangeNotifierProvider wrapper, now that there are two controllers to expose the same way). No screens consume this yet -- the 16 existing independent getCurrentUserProfile() call sites are migrated in a later step. Signed-off-by: g-k-s-03
Wires the avatar_url column, avatars storage bucket, uploadAvatar()/ removeAvatar() service methods, and UserProfileController from the earlier steps of issue 102 into the Edit Profile screen -- the only screen touched in this step. Flow: tapping the camera badge opens an action sheet (Gallery/Camera via image_picker), the picked image is shown in a preview dialog with Confirm/Cancel before anything is uploaded, Confirm calls SupabaseService().uploadAvatar() with a spinner replacing the camera icon while in flight, and on success updates UserProfileController.updateAvatarUrl() (via context.read, per the provider registered in main.dart) plus a success snackbar; failures show an error snackbar with the returned error instead. A "Remove Photo" button appears only when an avatar is currently set, behind its own confirmation dialog (destructive action, matching the existing logout-confirmation pattern in profile_screen.dart), then follows the same remove/update-provider/snackbar flow. A new _isAvatarUpdating flag (separate from the existing _isLoading used by Save Profile) disables the camera button and Remove button and shows a spinner while an upload or remove is in flight, preventing double-taps. No shared initials-avatar widget existed in lib/widgets/custom_widgets.dart, so the avatar rendering (circular network image with loading/error fallback, or deterministic-color initials when no avatar_url is set) is implemented locally in this screen, reusing the same name-hashCode-to-color palette already used in team_members_screen.dart for consistency. No other screen was touched in this step. Signed-off-by: g-k-s-03
Part A -- shared avatar widget, rendered everywhere: Extracts a UserAvatar widget (lib/widgets/custom_widgets.dart), plus shared avatarColorForName()/avatarInitialsForName() helpers, from the avatar-or-initials rendering that was previously duplicated between edit_profile_screen.dart and team_members_screen.dart's local _getAvatarColor. Both screens now use the shared widget. Real avatar rendering (via UserAvatar) is added to: - profile_screen.dart: the current user's own header avatar. - dashboard_screen.dart: the "Welcome back" header avatar. - chat_screen.dart: wires up the previously dead ChatMessage.avatarUrl field (declared but never set or read) so the current user's chat bubbles show their real avatar instead of a static person icon. Part B -- sync via UserProfileController: profile_screen.dart and dashboard_screen.dart -- the two screens whose entire purpose includes displaying the current user's own identity -- are migrated off their independent getCurrentUserProfile() fetches onto UserProfileController, read reactively via context.watch() in build() so both screens re-render immediately when the avatar changes on another screen (e.g. Edit Profile), and via context.read() for one-off actions (team switch triggers controller.refresh(forceRefresh: true) instead of a local reload). UserProfileController.refresh() is now called once, fire-and-forget, in HomeScreen.initState() -- the single convergence point for every "entering the authenticated app" path, since splash screen (existing session) and login/signup/OTP-verify/team-selection all navigate directly to HomeScreen, bypassing splash. Consuming screens use context.watch(), so they rebuild automatically once this async refresh completes rather than needing to race it. chat_screen.dart's own getCurrentUserProfile() call (team_id lookup for loading team members/tasks/tickets for AI context) is deliberately left untouched -- it uses the profile for query scoping, not for displaying the current user's identity. The remaining getCurrentUserProfile() call sites (calendar_screen, create_task_screen, task_detail_screen, task_screen x2, meeting_screen, meeting_detail_screen, ticket_screen, ticket_detail_screen x2, create_ticket_screen, workspace_screen x3) are also left untouched: none of them render the current user's own avatar/identity, they only use the profile for team_id/role-based query scoping and permission checks, which is out of scope for this avatar-rendering/sync step. team_members_screen.dart's per-member fetch is unrelated on purpose -- it renders OTHER users' data, which UserProfileController intentionally does not hold. Signed-off-by: g-k-s-03
…efore refresh completes profileController.profile is null until UserProfileController.refresh() (fired-and-forgotten in HomeScreen.initState()) actually resolves. Tapping Edit Profile before that completes force-unwrapped a null value and crashed -- reproduced live shortly after login/tab navigation. Replace the inline onTap closure with _openEditProfile(): if profile is already loaded, navigate immediately as before; otherwise show the existing full-screen _isLoading state (same pattern already used for _switchTeam in this file) while awaiting a fresh refresh(), then navigate once loaded, or show an error snackbar and stay put if the refresh still comes back empty. No forced unwrap remains anywhere in the method. Audited the rest of the codebase for the same bug class (grepped for "profileController.profile!" and ".profile!" across lib/screens/, plus any other force-unwrap of UserProfileController data): this was the only call site. dashboard_screen.dart and chat_screen.dart, the two other screens migrated onto UserProfileController in the previous step, only ever use its nullable getters (fullName?.trim(), avatarUrl, teamId) or already await refresh() before touching .profile, so they were not affected. flutter analyze run: no new errors or warnings introduced (170 pre-existing info/warning-level issues across the codebase, unrelated to this change). Signed-off-by: g-k-s-03
Image.file(pickedFile) in the avatar preview dialog crashed on Flutter Web with "Image.file is not supported on Flutter Web" -- XFile from image_picker has no real filesystem path on web, only dart:io's File requires one. edit_profile_screen.dart: read the picked XFile's bytes once via picked.readAsBytes() (works on every platform, including web) and thread Uint8List through the preview dialog (Image.memory instead of Image.file) and the upload call, instead of wrapping picked.path in a dart:io File. This also required changing SupabaseService.uploadAvatar() itself: it took a dart:io File and called StorageFileApi.upload(), which performs a real file read and is not supported on web either. Switched it to accept Uint8List and call StorageFileApi.uploadBinary() instead, which the Supabase storage client explicitly documents as "Can be used on the web." dart:io is no longer imported in either file -- imageFile was uploadAvatar()'s only use of File in supabase_service.dart. removeAvatar() and every other avatar/storage code path were already platform-safe (no File involved) and needed no changes. flutter analyze: 0 errors (same pre-existing info-level lints as before this change; nothing new).

… reactive chat avatar, SQL naming)
Issue 1 -- chat avatar not reactive:
ChatMessage no longer snapshots avatarUrl at send-time. _ChatBubble's
_buildAvatar now reads it live via
context.select<UserProfileController, String?>((c) => c.avatarUrl) --
select rather than watch, so the bubble only rebuilds when avatarUrl
specifically changes. Old messages in the chat history now pick up a
new avatar immediately after it changes, instead of being frozen at
whatever was current when the message was sent. Removed the now-unused
avatarUrl field/constructor param from ChatMessage after confirming (by
grep) it had no other consumers.
Issue 2 -- stale cached avatar image after re-upload:
The storage path is fixed per user (<user_id>/avatar.jpg), so the
public URL never changes between uploads, and Image.network/browser
caching keyed on that URL could keep showing the old image after a
successful re-upload. SupabaseService.uploadAvatar() now appends
'?v=<millisecondsSinceEpoch>' to the public URL before it's used
anywhere, and that single versioned value is what gets saved to
avatar_url via updateUserProfile, returned in the result map, and
(already, via the existing result['avatar_url'] plumbing in
edit_profile_screen.dart) passed to UserProfileController.updateAvatarUrl()
-- traced the full path to confirm no code point still reads the bare
publicUrl.
Issue 3 -- removeAvatar() reported success even on a real deletion
failure:
The storage .remove() call was wrapped in a catch-all that treated
every exception as "object already gone, fine." Checked the actual
storage_client 2.4.1 package source (fetch.dart's _handleError):
non-2xx responses are thrown as StorageException with statusCode set
to the HTTP status code string (e.g. '404'). removeAvatar() now
catches StorageException specifically and only proceeds to clear
avatar_url when the exception looks like a genuine not-found
(statusCode == '404', error == 'not_found', or message containing
"not found"); any other StorageException now returns
{'success': false, 'error': ...} without touching avatar_url, so a
real failure (permissions, network, etc.) surfaces to the UI instead
of being silently swallowed while the file stays in storage.
Issue 4 -- SQL policy naming (SQLFluff RF05):
Renamed all four storage.objects policies in both
sqls/11_avatar_url_and_storage.sql and
supabase/migrations/20251021110000_avatar_url_and_storage.sql (DROP
POLICY IF EXISTS and CREATE POLICY lines) from quoted human-readable
names to unquoted snake_case: avatars_public_select,
avatars_owner_insert, avatars_owner_update, avatars_owner_delete. Both
files remain byte-identical (verified via diff).
Issue 5 (Android lost-data-recovery suggestion) intentionally not
addressed here -- deferred as a separate follow-up per instructions.
flutter analyze: 0 errors; same 170 pre-existing info/warning-level
issues as before this change, none new.

Closes #102
📝 Description
Implements profile avatar upload with real-time, app-wide synchronization, as requested in #102. Previously, users had no way to personalize their profile with a photo — every screen showed a generic person icon or plain initials with no visual identity for team members.
This PR adds the full flow: users can upload a photo from Edit Profile, preview it before committing, and see it reflected instantly across every screen that shows their identity — Profile, Dashboard, and Chat — with no app restart or re-login required. Users can also remove their photo at any time, reverting cleanly to an initials-based fallback.
