wrap method Null safety

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

Return a copy of this inherited theme with the specified 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 SfSliderTheme? ancestorTheme =
      context.findAncestorWidgetOfExactType<SfSliderTheme>();
  return identical(this, ancestorTheme)
      ? child
      : SfSliderTheme(data: data, child: child);
}
