How to make Checkbox shape rounded in CheckboxListTile in Flutter?

Question

I have implemented CheckboxListTile in a flutter. The default checkbox is square. But I need a circular Checkbox, just like the one in the below image. Is there any way to do it? Thanks for the help :)

class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  @override
  Widget build(BuildContext context) {
    return CheckboxListTile(
      title: const Text('Animate Slowly'),
      value: timeDilation != 1.0,
      onChanged: (bool? value) {
        setState(() {
          timeDilation = value! ? 10.0 : 1.0;
        });
      },
      secondary: const Icon(Icons.hourglass_empty),
    );
  }
}

If you want to change the default checkbox theme you need to override it like this

class Exmaple extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final theme = Theme.of(context);
    final oldCheckboxTheme = theme.checkboxTheme;

    final newCheckBoxTheme = oldCheckboxTheme.copyWith(
      shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(100)),
    );

    return Theme(
      data: theme.copyWith(checkboxTheme: newCheckBoxTheme),
      child: CheckboxListTile(
        onChanged: (_) {},
        value: false,
      ),
    );
  }
}
