The answer above( by Tarek Baz) is correct, however in some special cases (like deep/complicated widget tree) it might not be enough and you might have to pass the physics parameter to the ListView.builder() function.

ListView.builder( 
physics: const AlwaysScrollableScrollPhysics(), 
itemCount: .... ... )
