ListView Builder Widget in Hindi | what is listview in flutter

Описание: In Flutter, the `ListView.builder` widget is commonly used to create a scrollable list of items efficiently. It builds the list dynamically based on the number of items in the data source, which helps in optimizing memory usage and performance.

Here's an example of how to use the `ListView.builder` widget in Flutter:

In the above example, `itemCount` represents the total number of items in your list, and `itemBuilder` is a callback function that builds each item in the list. Inside the `itemBuilder`, you can access the current item using the `index` parameter.

In this case, we are using `ListTile` as the item widget. You can replace it with any other widget based on your requirements.

Make sure to replace `itemList` with your actual list of items. Each item can be an object with properties such as `title` and `subtitle` as shown in the example.

The `onTap` callback is triggered when an item is tapped. You can add your own logic to handle the tap event.

Remember to place the `ListView.builder` widget inside a parent widget, such as a `Container`, `Column`, or `Scaffold`, to ensure it is properly rendered in the UI.
