  1. @override
Widget wrap(
  1. BuildContext context,
  2. Widget child
)

This implementation for TooltipTheme is typical:

Widget wrap(BuildContext context, Widget child) {
  return TooltipTheme(data: data, child: child);
}

Implementation

@override
Widget wrap(BuildContext context, Widget child) {
  final SfGaugeTheme? ancestorTheme =
      context.findAncestorWidgetOfExactType<SfGaugeTheme>();
  return identical(this, ancestorTheme)
      ? child
      : SfGaugeTheme(data: data, child: child);
}
