+title: Material 3 Tokens Update in Flutter
+description: >-
+  The latest Material Design 3 tokens(v6.1) have been applied to the Flutter
+  Material library.
+---
+
+## Summary
+
+The Material Design tokens updated the mapping of 4 color roles (only in Light
+mode) to be more visually appealing while retaining accessible contrast. Testing
+identified this change as [non-breaking] in Flutter, but some customers might
+notice this small change. The update affected the following color properties:
+
+* On-primary-container (Primary10 to Primary30)
+* On-secondary-container (Secondary10 to Secondary30)
+* On-tertiary-container (Tertiary10 to Tertiary30)
+* On-error-container (Error10 to Error30)
+
+Widgets that have been using these roles with their default value might look
+different.
+
+Additionally, the Material 3 tokens updated the border color of Chips from
+`ColorScheme.outline` to `ColorScheme.outlineVariant` to improve visual
+hierarchy between chips and buttons. Chips (`Chip`, `ActionChip`, `ChoiceChip`,
+`FilterChip`, and `InputChip`) that have been using the chip border tokens may
+look different.
+
+## Migration guide
+
+The differences in the mappings of the color roles are small. Use
+`ColorScheme.copyWith` to revert to the original default colors:
+
+Code before migration:
+
+```dart
+final ColorScheme colors = ThemeData().colorScheme;
+```
+
+Code after migration:
+
+```dart
+final ColorScheme colors = ThemeData().colorScheme.copyWith(
+  onPrimaryContainer: const Color(0xFF21005D),
+  onSecondaryContainer: const Color(0xFF1D192B),
+  onTertiaryContainer: const Color(0xFF31111D),
+  onErrorContainer: const Color(0xFF410E0B),
+);
+```
+
+After applying the token update, the default border color of M3 chips looks
+lighter. Take `ActionChip` as an example:
+
+Code before migration:
+
+```dart
+final Widget chip = ActionChip(
+  label: const Text('action chip'),
+  onPressed: () {},
+);
+```
+
+Code after migration:
+
+```dart
+final Widget chip = ChipTheme(
+  data: ChipThemeData(
+    side: BorderSide(
+      color: Theme.of(context).colorScheme.outline
+    ),
+  ),
+  child: ActionChip(
+    label: const Text('action chip'), 
+    onPressed: () {}
+  )
+);
+```
