​

UI Specification: Settings & Profile (Phase 7 - FINAL)

​

Overview

• Settings Screen (Main)
• Edit Profile Screen

​

Design Goals

1. iOS-Native Feel: Use grouped list styling (CupertinoFormSection) consistent with iOS Settings app
2. Clear Organization: Group related settings logically for easy scanning
3. Data Control: Give users full control over their data, privacy, and account
4. Accessibility: Full VoiceOver support, Dynamic Type, WCAG 2.1 AA compliance
5. Safety First: Destructive actions require confirmation dialogs

​

Screen 1: Settings Screen (Main)

​

Purpose

​

User Flow

• Tab Bar → Profile tab (person.circle.fill icon)
• Entry: User taps Profile icon in bottom tab bar

• Edit Profile → Edit Profile screen
• Change Password → Password change form
• Subscription → Subscription Options screen (from Phase 6)
• Export Data → Email with download link
• Delete Account → Confirmation dialog → Account deletion
• Sign Out → Confirmation dialog → Welcome screen

• Profile photo: 120×120pt

• Same layout (vertical scroll)
• No special landscape adaptations

• Field heights increase to accommodate larger text
• Labels scale with Dynamic Type
• Helper text may wrap to 2 lines
• Character counts remain inline (not wrapped)

• Horizontal margins: 12pt
• Profile photo: 100×100pt (reduce from 120pt)
• Tighter spacing

​

Accessibility

• Swipe right through elements:
  • “Edit Profile, heading level 1”
  • “Cancel, button, double-tap to cancel”
  • “Save, button, disabled/enabled, double-tap to save”
  • “Profile photo, Ryan Thompson, button, double-tap to change”
  • “Change Photo, button, double-tap to select new photo”
  • “Display Name, text field, Ryan Thompson, double-tap to edit”
  • “This name will appear on your profile”
  • “Bio, optional, text field, multiline, double-tap to edit”
  • “142 of 150 characters”

• All text uses iOS Dynamic Type
• Fields expand to fit larger text
• Test at AX5 (largest size)

• All text meets WCAG 2.1 AA (4.5:1 minimum)
• Error text (red): 4.5:1 on background
• Placeholder text (gray): 4.5:1 on background

• Tab order: Photo → Change Photo → Display Name → Bio → Save
• Enter key: Saves profile (if valid)
• Escape key: Cancels (with confirmation if unsaved changes)

• Dialogs: Fade in instead of scale
• Screen transitions: Fade instead of slide
• Field shake: Skip animation, just show error text

​

Edge Cases & Error Handling

• Validation: Real-time validation after blur
• Error: “Name is required” (red text below field)
• Save Button: Disabled until valid

• Validation: Real-time character count
• Prevention: Text field enforces maxLength (Flutter handles)
• UI: Character counter doesn’t show (enforced at input level)

• Validation: Real-time character count
• Prevention: Text field enforces maxLength
• UI: Counter turns red at >145 chars

• Error: Alert: “Photo upload failed. Your name and bio were saved.”
• Retry: User can retry from Settings screen (Change Photo)
• Fallback: Profile updated without new photo

• Error: Alert: “Update failed. Please check your connection and try again.”
• Retry: “Retry” button in alert
• Cancel: “Cancel” button dismisses alert, stays on Edit Profile

• Behavior: Only the most recent selection is kept
• Upload: Only upload once on Save (not on each selection)

• Behavior: All changes lost, returns to Settings
• Photo: Selected photo not uploaded, reverts to original

• Behavior: API call still made (in case of sync issues)
• UI: Success toast shown
• Optimization (future): Detect no changes, skip API call

• Both alerts announced immediately
• Password field: “Password, secure text field, double-tap to edit”
• Error announced when password incorrect
• Loading state: “Deleting account, loading”

Summary: Phase 7 Complete

1. Settings Screen (Main) - 9 sections, 14+ interactive elements
2. Edit Profile Screen - Photo upload, 2 form fields, save/cancel

• ✅ Account management (edit profile, change password, delete account)
• ✅ App settings (notifications, daily reminder time, theme selection)
• ✅ Data & privacy (export data, delete account)
• ✅ Help & support (FAQ, privacy policy, terms)
• ✅ Sign out functionality
• ✅ Profile photo upload (camera/library)
• ✅ Form validation (name required, bio max length)
• ✅ Unsaved changes confirmation
• ✅ iOS-native feel (grouped lists, segmented controls, action sheets, alerts)

​

Next Steps for Development

​

Priority Order:

1. Settings Screen: Implement all rows, sections, and navigation
2. Edit Profile Screen: Implement form, photo upload, validation
3. Time Picker Modal: Daily reminder time selection
4. Theme Picker Modal: App theme selection (auto/light/dark)
5. Export Data Flow: Backend integration for data export
6. Delete Account Flow: Multi-step confirmation with password verification
7. Sign Out Flow: Session management and navigation

​

Critical Integrations:

• Photo Upload: Use image_picker package for camera/library access
• Local Notifications: Use flutter_local_notifications for daily reminders
• Theme Management: Use provider or riverpod for app-wide theme state
• API Endpoints:
  • PATCH /api/users/profile - Update profile
  • POST /api/users/profile/photo - Upload photo
  • POST /api/users/export - Request data export
  • DELETE /api/users/account - Delete account (soft delete)

​

Testing Requirements:

• ✅ All toggle switches functional
• ✅ Time picker saves correctly and schedules notifications
• ✅ Theme changes apply immediately
• ✅ Photo upload/remove works on all devices
• ✅ Form validation prevents empty name
• ✅ Unsaved changes confirmation shows when needed
• ✅ Delete account requires password and shows confirmations
• ✅ Sign out clears session and returns to Welcome
• ✅ VoiceOver navigation works for all elements
• ✅ Dynamic Type scales properly at all sizes
