Flutter ListView | Flutter ListView builder

Flutter ListView

In Flutter, a ListView is a scrollable list of widgets. You can create a ListView to display a scrolling list of items. Whereas, ListView.builder is a more efficient way to create a list of items in Flutter, especially when dealing with a large number of items. It only creates widgets for the items that are currently visible on the screen, leading to improved performance.
