Change the cursor to pointer in url_launcher Link widget

Question

How can I change the cursor to pointer when a user hovers over the link on web? I have tried MouseRegion and it's not working:

import 'package:url_launcher/link.dart';

class UserAgreementText extends StatelessWidget {
  const UserAgreementText({super.key});

  @override
  Widget build(BuildContext context) {
    final theme = Theme.of(context);
    return Wrap(
      children: [
        RichText(
          textAlign: TextAlign.center,
          text: TextSpan(
            text: 'By continuing, you accept our ',
            style: Theme.of(context).textTheme.bodySmall,
            children: <InlineSpan>[
              WidgetSpan(
                alignment: PlaceholderAlignment.baseline,
                baseline: TextBaseline.alphabetic,
                child: MouseRegion(
                  onEnter: (_) => SystemMouseCursors.click,
                  onExit: (_) => SystemMouseCursors.basic,
                  child: Link(
                    target: LinkTarget.blank,
                    builder: (context, follow) => Text(
                      "tos".tr(),
                      style: theme.textTheme.bodyMedium?.copyWith(
                        fontSize: 12,
                        color: theme.colorScheme.primary,
                      ),
                    ),
                    uri: Uri.parse(Constants.legals.tos),
                  ),
                ),
              ),
              const TextSpan(text: ' and '),
              WidgetSpan(
                alignment: PlaceholderAlignment.baseline,
                baseline: TextBaseline.alphabetic,
                child: Link(
                  target: LinkTarget.blank,
                  builder: (context, follow) => Text(
                    "pp".tr(),
                    style: theme.textTheme.bodyMedium?.copyWith(
                      fontSize: 12,
                      color: theme.colorScheme.primary,
                    ),
                  ),
                  uri: Uri.parse(Constants.legals.pp),
                ),
              ),
            ],
          ),
        ),
      ],
    );
  }
}

Answer 1

onEnter and onExit are void method. in order to change the cursor, you can put

MouseRegion(
 cursor: SystemMouseCursors.click,//
 child: 
)
