Same problem with OvalTopBorderClipper().

error: The argument type 'OvalTopBorderClipper' can't be assigned to the parameter type 'CustomClipper<Rect>?'. (argument_type_not_assignable at [my_app] lib/screens/dashboard/profile/ui_tab_profile.dart:46)

Reason: OvalTopBorderClipper extends CustomClipper (correct) with type <Path> referred to here in package:flutter/material.dart, however ClipOval clipper is defined with CustomClipper<Rect>? found here.

i.e. OvalTopBorderClipper extends CustomerClipper<Path> isn't the same type as CustomClipper<Rect>? from ClipOval.

Seems like a blatant bug to me that has yet to be corrected. Happening to me as well

Using ClipPath instead of ClipOval resolved the issue.

[AbdullahProjects]

Hey developers! Use the ClipPath() widget with the OvalTopBorderClipper() will resolve this issue.

Suggestion for Package Developer:

Hi @lohanidamodar, Here's a suggestion to help improve this package and avoid confusion: (2 ways):

1. Update the documentation: Guide developers to use ClipPath() instead of ClipOval() when working with OvalTopBorderClipper().

2. Consider changing the clipper type: Alternatively, update the OvalTopBorderClipper() concrete class by changing the generic type from CustomClipper<Path> to CustomClipper<Rect>, since ClipOval() only accepts a CustomClipper<Rect>.
