mte90 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.
