Another exception was thrown: setState() or markNeedsBuild() called during build Error in flutter - flutter

Question

Im new to flutter and working on an ecommerce flutter app. When im trying to navigate to search screen its giving some error. Please find the below codes for your reference and help to resolve.
Error :
The following assertion was thrown while dispatching notifications for SearchProvider:
setState() or markNeedsBuild() called during build.
This _InheritedProviderScope<SearchProvider?> widget cannot be marked as needing to build because
the framework is already in the process of building widgets. A widget can be marked as needing to
be built during the build phase only if one of its ancestors is currently building. This exception
is allowed because the framework builds parent widgets before children, which means a dirty
descendant will always be built. Otherwise, the framework might not visit this widget during this
build phase.
The widget on which setState() or markNeedsBuild() was called was:
_InheritedProviderScope<SearchProvider?>
The widget which was currently being built when the offending call was made was:
SearchScreen

Answer 1

Try to use initial function calling in initState instead of build function
#override
void initState() {
WidgetsBinding.instance!.addPostFrameCallback((_) {
Provider.of<SearchProvider>(context, listen: false).cleanSearchProduct();
Provider.of<SearchProvider>(context, listen: false).initHistoryList();
});
super.initState();
}
