useArg function
dynamic
useArg()
Get a map of the page from Hooks.
It is only available within the build
method.
Basically it returns the RouteQuery data passed from the previous page.
If the RouteQuery data is not found, the map stored in PageHookWidget is retrieved.
Implementation
DynamicMap useArg() {
final context = useContext();
return ModalRoute.of(context)?.settings.arguments as DynamicMap? ??
UIScope.of(context)._map;
}
