I am currently using the pull_to_refresh package in flutter and code looks something like this

final RefreshController refreshController = RefreshController(initialRefresh: true);


SmartRefresher(
 controller: refreshController,
 onRefresh: (){
     // my refresh function
 },
 enablePullDown: true,
 scrollController: scrollController,
 child:ListView()
)

I tried using the command

refreshController.requestRefresh(needCallback: false);

but it does not show the loader on the top of the screen.

I need a solution that can show the loader at the top of the screen without calling the actual refresh function.
