ListView

ListView is a scrollable widget in Flutter that displays a list of items. It is used when you have a large amount of data to display in a limited space. ListView can be used with various types of widgets to create a variety of effects, such as displaying images, videos and more.

Example:

ListView(
  children: <Widget>[
    ListTile(title: Text('Item 1')),
    ListTile(title: Text('Item 2')),
    ListTile(title: Text('Item 3')),
  ],
)

itemBuilder

The itemBuilder attribute is used to create a widget for each item in the list. It takes a function that returns a widget and has two parameters: the context and the index of the item.

Example:

ListView.builder(
  itemCount: items.length,
  itemBuilder: (BuildContext context, int index) {
    return ListTile(
      title: Text(items[index]),
    );
  },
)

This will create a ListView that displays a ListTile for each item in the items list.
