Material Design for Flutter

Material Design is an open-source design system built and supported by Google designers and developers.

The latest version, Material 3, enables personal, adaptive, and expressive experiences—from dynamic color and enhanced accessibility, to foundations for large screen layouts, and design tokens. Flutter is in the process of migrating to Material 3.

Note: A few facts about Material 3 (M3), the next generation of Material Design:

Most Flutter widgets are already migrated to M3, but you can follow progress on the Material 3 Flutter GitHub project and the GitHub umbrella issue.
You can opt in to Material 3 using the useMaterial3 flag. However, your UI might be inconsistent until all of Flutter and your code are migrated.
For the latest list of Flutter’s widgets that are affected by the useMaterial3 flag, see Affected widgets.
The vast majority of Flutter widgets have similar behavior in M2 and M3, so those widget names are unchanged. However, a couple widgets have substantially different behavior in M3, so new widgets have been created.
Once migration is complete, Material 3 will become the Material library’s default look and feel.
Support for Material 2 will eventually be removed according to Flutter’s deprecation policy.
