To implement Material Design 3 theming in Flutter, configure the `MaterialApp` widget with `ThemeData` using `useMaterial3: true` and generate a `ColorScheme` from a seed color. This enables M3 components and adaptive theming across your app.

Dynamic color theming with Material You in Flutter works by using the `DynamicColorBuilder` package to generate adaptive color schemes based on user device wallpaper preferences. This ensures the app UI matches system settings dynamically.

The best way to configure a baseline M3 color scheme in Dart is setting `useMaterial3: true` in `ThemeData` alongside `colorSchemeSeed`. This automatically derives a complete, harmonious Material Design 3 color palette.

You need the `DynamicColorBuilder` package specifically for Material You dynamic color schemes reacting to device settings. For baseline M3 without OS-level wallpaper adaptation, standard Flutter `ColorScheme.fromSeed` is sufficient.

You should use optional M3 Expressive packages alongside Flutter's built-in material library when you need advanced M3 theming features and custom UI components beyond standard Material Design 3 component styling capabilities.
