+  ```yaml
+  flutter_gen:
+    assets:

+      outputs: 
+        class_name: MyAssets # Default is `Assets`
+
+    fonts:
+      # Optional
+      outputs:
+        class_name: MyFontFamily # Default is `FontFamily`
+
+    colors:
+      # Optional

+  ```
+- [#294](https://github.com/FlutterGen/flutter_gen/pull/294) [**BREAKING CHANGES**] Moved the `style` and `package_parameter_enabled` to under assets.outputs scope.

+    assets:
+      package_parameter_enabled: true
+      style: snake-case
+      outputs:
+        class_name: MyAssets
+
+  flutter_gen:
+    # ...
+    assets:
+      outputs:
+        class_name: MyAssets
+        package_parameter_enabled: true
+        style: snake-case
+  ```
+
+**Bug fix**
