Conflig with Flutter 3.13.0

../../../../.pub-cache/hosted/pub.dev/skeleton_text-3.0.0/lib/skeleton_text.dart:70:49: Error: The argument type 'BorderRadius?' can't be assigned to the parameter type 'BorderRadiusGeometry' because 'BorderRadius?' is nullable and 'BorderRadiusGeometry' isn't.
- 'BorderRadius' is from 'package:flutter/src/painting/border_radius.dart' ('/Library/development/flutter/packages/flutter/lib/src/painting/border_radius.dart').
- 'BorderRadiusGeometry' is from 'package:flutter/src/painting/border_radius.dart' ('/Library/development/flutter/packages/flutter/lib/src/painting/border_radius.dart').
borderRadius: widget.borderRadius as BorderRadius?,
^

The error occurs in skeleton_text.dart line 70, where a nullable BorderRadius? is being passed where a non-nullable BorderRadiusGeometry is expected. Start by examining the widget.borderRadius property and the constructor it's being passed to. Look at the Flutter 3.13.0 migration guide for BorderRadius changes. The fix likely involves removing the cast or providing a default value. Run the package tests to verify the change resolves the type error.
