Mobile UX Core

Priority: P0 (CRITICAL)

Universal UX principles for mobile applications.

Guidelines

  • Touch Targets: Min 44x44pt (iOS) / 48x48dp (Android). Add padding if needed.
  • Safe Areas: Wrap content in SafeArea/WindowInsets. Avoid notches.
  • Interactions: Use active states (no hover). Haptic feedback (short).
  • Typography: Min 16sp body. Line height 1.5x.
  • Keyboards: Auto-scroll inputs. Set InputType (email/number) & Action.

Code Examples

// ✅ Correct Target
IconButton(icon: Icon(Icons.close), padding: EdgeInsets.all(12))

// ❌ Too Small
Icon(Icons.close, size: 16)

Anti-Patterns

  • No Hover Effects: Mobile has no cursor. Use pressed states.
  • No Tiny Targets: All clickable elements ≥44pt.
  • No Fixed Bottom: Account for Home Indicator & Keyboard.
  • No OS Mix: Use Material (Android) & Cupertino (iOS) conventions.
