The Evolution: Material 3 (Material You)
Material 3 is the latest version of Google’s open-source design system. For an Architect, the shift to M3 is significant because it introduces Dynamic Color—where the app's primary, secondary, and tertiary palettes are derived from the user's wallpaper. In your Revochamp native modules, implementing this ensures your generated previews feel personal and consistent with the user's system-wide theme.
- Core Material Components
Native Android provides high-level components that handle elevation, ripple effects, and accessibility out of the box. In 2026, these are primarily implemented using Jetpack Compose, though the XML-based Material Components library (MDC) is still used for legacy Runner maintenance.
- TopAppBar: Handles navigation and actions. M3 supports four types: center-aligned, small, medium, and large.
- Floating Action Button (FAB): The primary action button. M3 introduces a new 'Square-ish' rounded corner shape.
- Navigation Bar: Replaces BottomNavigationView with a more accessible, pill-shaped indicator for active states.
- Cards: Provided in Elevated, Filled, and Outlined variants to match the content hierarchy.
- Theming with Jetpack Compose
Theming in native Android is now handled through the MaterialTheme composable. Unlike Flutter's ThemeData, native Compose themes are often split into Color.kt, Type.kt, and Shape.kt for better modularity in large-scale engineering projects.
- Adaptive Layouts
With the rise of foldables and tablets, Material UI now emphasizes Window Size Classes. As a Technical Lead, you should use these to determine if your native AI preview should show a 'Navigation Rail' (on tablets) or a 'Bottom Navigation Bar' (on phones).
Material UI Comparison: Native vs. Flutter
| Feature | Android Native (M3) | Flutter Material |

| Color Engine | Monet (Dynamic Color) | ColorScheme / Material 3 flag |
| Implementation | Jetpack Compose / XML | Skia / Impeller Canvas |
| Theming | Composable MaterialTheme | ThemeData Widget |
| Components | Native OS-optimized | Flutter-drawn 'lookalikes' |
| Responsiveness | Window Size Classes | LayoutBuilder / MediaQuery |
