عيني يا صديقي بص هنا علي ال list view api.flutter.dev/flutter/widgets/ListView/ListView.html هتلاقيه بيقولك It is usually more efficient to create children on demand using ListView.builder because it will create the widget children lazily as necessary. يعني ال .builder بتبقي lazy يعني بتجيب ال items الي اليوزر شايفها فقط و الباقي زي ما هو لحد ما يعمل سكرول و يبدأ يجيب منهم و دي كانت مقارنة بينهم علي stack over flow تأكدلك كلامي ListView: Creates a scrollable, linear array of widgets from an explicit List. This constructor is appropriate for list views with a small number of children because constructing the List requires doing work for every child that could possibly be displayed in the list view instead of just those children that are actually visible. ListView.builder Creates a scrollable, linear array of widgets that are created on demand. This constructor is appropriate for list views with a large (or infinite) number of children because the builder is called only for those children that are actually visible.
