UI Redesign Proposal

Drop UI/UX Redesign Proposal

Note: Originally written as "FontelePay" with Flutter stack. Product has been rebranded to Drop using Next.js 16 + React 19 + Tailwind v4 + shadcn/ui. Design direction chosen: Forest Green (#0B6E35) + Gold (#D4A017) with Fraunces (brand) + DM Sans (body) typography. Retained for historical research reference.

Date: 2026-02-05 Status: Superseded — see brand/brand-guide.md for current design system

Executive Summary

Drop (originally FontelePay) needs a distinctive visual identity to compete with established neobanks (Revolut, N26, Monzo, Wise). This proposal outlines three design directions, recommended component library, color palettes, typography, and implementation roadmap.

Core Problem: Generic Tailwind-template aesthetics lack brand differentiation.

Solution: Custom design system with distinctive branding, purposeful micro-interactions, and mobile-first components.

3. Component Library Recommendation

Primary: Flutter Material 3 + Custom Design System

Why Flutter Material 3:

  • Native to Flutter stack (already chosen)
  • Built-in accessibility (WCAG compliant)
  • Dynamic color theming
  • Adaptive components for iOS/Android
  • Active development by Google

Implementation Approach:

// Theme Configuration Example
ThemeData fontelepayTheme = ThemeData(
  useMaterial3: true,
  colorScheme: ColorScheme.fromSeed(
    seedColor: Color(0xFF7C3AED), // Primary brand color
    brightness: Brightness.light,
  ),
  textTheme: GoogleFonts.interTextTheme(),
);

Recommended Flutter Packages

Package Purpose Version
flutter_bloc State management 8.x
go_router Navigation, deep linking 14.x
dio HTTP client 5.x
lottie Micro-interactions 3.x
flutter_animate Declarative animations 4.x
google_fonts Typography 6.x
flutter_svg Vector icons 2.x
shimmer Loading states 3.x

├── Atoms (smallest units)
│   ├── Colors
│   ├── Typography
│   ├── Icons
│   └── Spacing
├── Molecules (simple components)
│   ├── Button (primary, secondary, ghost)

│   └── CardWidget (virtual card display)
└── Templates (page layouts)
    ├── DashboardLayout
    ├── OnboardingLayout
    └── TransactionDetailLayout

4. Typography Recommendation

Primary Font: Inter

Why Inter:

  • Optimized for UI at small sizes
  • Tall x-height for screen legibility
  • Tabular figures for financial data
  • Free (Google Fonts)
  • Variable font support
  • Best non-proprietary alternative to SF Pro

Type Scale (Material 3):

Style Size Weight Line Height Usage
Display Large 57px 400 64px Hero numbers
Display Medium 45px 400 52px Balance display
Headline Large 32px 600 40px Screen titles
Headline Medium 28px 600 36px Section headers
Title Large 22px 500 28px Card titles
Title Medium 16px 500 24px Subtitles
Body Large 16px 400 24px Main content
Body Medium 14px 400 20px Secondary content
Label Large 14px 500 20px Buttons
Label Medium 12px 500 16px Captions

Alternative Pairing

Premium Option: Plus Jakarta Sans (headings) + Inter (body)

  • Plus Jakarta Sans has more personality
  • Creates visual hierarchy naturally
  • Both available on Google Fonts

5. Micro-Interactions & Animation

Animation Principles

  1. Duration Guidelines:

    • Micro-interactions: 50-200ms
    • Page transitions: 200-400ms
    • Complex animations: 400-600ms

  2. Easing:

    • Standard: Curves.easeOutCubic
    • Enter: Curves.decelerate
    • Exit: Curves.accelerate

Essential Animations

Component Animation Duration Trigger
Button Press Scale down 0.95 100ms onTapDown
Transaction Success Checkmark Lottie 600ms onComplete
Card Flip 3D rotation 400ms onTap
Balance Update Number morph 300ms onValueChange
Pull to Refresh Custom Lottie 800ms onRefresh
Skeleton Loading Shimmer Loop onLoading
Tab Switch Fade + slide 200ms onSelect

Lottie Animations to Create

  1. Success Checkmark - Payment confirmed
  2. Loading Spinner - Processing state
  3. Card Issuing - Virtual card generation
  4. Money Transfer - Send/receive animation
  5. Empty State - No transactions illustration
  6. Error State - Failed transaction
  7. Confetti - First transaction celebration

6. Component Redesign Priority

P0 - Critical (Week 1-2)

Component Current Issue Redesign Focus
Primary Button Generic Tailwind Custom shape, gradient option, haptic feedback
Input Field Basic styling Floating labels, validation states, currency formatting
Balance Card Flat, boring Glassmorphism, subtle animation, gradient background
Transaction Item List-like Card approach, merchant icons, category colors

P1 - Important (Week 3-4)

Component Current Issue Redesign Focus
Navigation Bar Standard tab bar Custom icons, animated indicators
Card Widget Static display 3D flip, Apple/Google Pay button integration
Amount Input Basic number Custom keypad, currency selector, max button
Profile Avatar Circle image Gradient border, online indicator

P2 - Enhancement (Week 5-6)

Component Current Issue Redesign Focus
Charts Basic lines Animated draw, touch interaction, gradients
Category Pills Plain buttons Icons, color coding, selection animation
Empty States Text only Lottie illustrations, CTAs
Notifications System default Custom in-app notifications

7. Dark Mode Implementation

Design Principles

  1. Not just inverted colors - Redesign each surface layer
  2. Reduced contrast - Use off-white (#F1F5F9) instead of pure white
  3. Elevated surfaces = lighter - Higher elevation = lighter gray
  4. Desaturated accent colors - Reduce saturation 10-20% for dark mode
  5. Test contrast ratios - Minimum 4.5:1 for text (WCAG AA)

Surface Elevation (Dark Mode)

Elevation Background Use Case
0 #09090B Page background
1 #18181B Cards, inputs
2 #27272A Modals, dropdowns
3 #3F3F46 Hover states

Implementation

ColorScheme darkScheme = ColorScheme.fromSeed(
  seedColor: Color(0xFF7C3AED),
  brightness: Brightness.dark,
  surface: Color(0xFF18181B),
  onSurface: Color(0xFFF1F5F9),
);

8. Accessibility Requirements

WCAG 2.1 AA Compliance

Requirement Implementation
Color Contrast Minimum 4.5:1 (text), 3:1 (large text)
Touch Targets Minimum 48x48dp
Focus States Visible ring on all interactive elements
Screen Reader Semantic labels on all widgets
Dynamic Type Support system font scaling
Reduce Motion Respect MediaQuery.disableAnimations

Testing Tools

  • Flutter Accessibility Scanner
  • Contrast ratio calculator
  • VoiceOver/TalkBack manual testing

9. Implementation Roadmap

Phase 1: Foundation (Week 1-2)

  • Define final color palette (choose Option A/B/C)
  • Configure Flutter Material 3 theme
  • Set up typography system
  • Create color tokens file
  • Implement dark mode toggle

Phase 2: Core Components (Week 3-4)

  • Redesign Button component (all variants)
  • Redesign Input component (text, PIN, amount)
  • Redesign Card components (balance, transaction)
  • Implement loading states (shimmer, skeleton)
  • Add Lottie animation package

Phase 3: Feature Components (Week 5-6)

  • Build AccountCard with animations
  • Build TransactionList with pull-to-refresh
  • Build PaymentForm with amount keyboard
  • Build CardWidget with 3D flip

Phase 4: Polish (Week 7-8)

  • Create Lottie animations
  • Implement micro-interactions
  • Accessibility audit
  • Dark mode testing
  • Performance optimization

10. My Recommendation

Go with Option C: "Nordic Minimal"

Reasons:

  1. Differentiation - Most neobanks use dark (Revolut, N26) or warm (Monzo) palettes. Electric violet is distinctive.
  2. Scalability - Minimal design ages better and accommodates new features easily.
  3. Trust - Clean design signals competence and transparency.
  4. Dark Mode - Minimal palettes translate better to dark mode.
  5. EU Market - Scandinavian design resonates well with European users.

Typography: Inter + Satoshi pairing for personality without sacrificing legibility.

Implementation: Flutter Material 3 as foundation, custom component library on top.

Next Steps

  1. Review this proposal - Select design direction (A, B, or C)
  2. Approve color palette - Or request modifications
  3. Create Figma design file - Based on chosen direction
  4. Build component library - Flutter implementation
  5. Iterate - Refine based on user testing
