+### Rebuild list
+Starting from version 5.9.0, ScreenUtilInit won't rebuild the whole widget tree, instead it will mark widget needs build only if:
+- Widget is not a flutter widget (widgets are available in [Flutter Docs](https://docs.flutter.dev/reference/widgets))
+- Widget does not start with underscore (`_`)
+- Widget does not declare `SU` mixin
+- `reponsiveWidgets` does not contains widget name
+
+If you have a widget that uses the library and doesn't meet these options you can either add `SU` mixin or add widget name in responsiveWidgets list.
+
 ### Initialize and set the fit size and font size to scale according to the system's "font size" accessibility option 
 
 Please set the size of the design draft before use, the width and height of the design draft.
