- StretchyHeader.singleChild({Key? key, required HeaderData headerData, required Widget child, double? displacement, VoidCallback? onRefresh})
Properties
- displacement → double
-
The distance from the child's top or bottom edge to where the refresh
indicator will settle. During the drag that exposes the refresh indicator,
its actual displacement may significantly exceed this value.
