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
dart
// ✅ 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.
