wrap method

@override Widget wrap(BuildContext context, Widget child)

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) {
  ComponentTheme<T>? ancestorTheme =
      context.findAncestorWidgetOfExactType<ComponentTheme<T>>();
  // if it's the same type, we don't need to wrap it
  if (identical(this, ancestorTheme)) {
    return child;
  }
  return ComponentTheme<T>(
    data: data,
    child: child,
  );
}
