Final answer:
To display data in a ListView widget, the ListView.Builder class is used. It creates items on-demand when they are scrolled onto the screen, which is efficient for large data sets.
Step-by-step explanation:
To display data in a ListView widget, you can use the ListView.Builder class. This constructor of the ListView widget is specially designed for building a list view that creates items on demand. This is especially useful if you're dealing with a large data set because it's more efficient than creating all items at once. The ListView.Builder constructor takes an IndexedWidgetBuilder, which is responsible for building the widgets for each item in the list as they're scrolled onto the screen. It also takes an itemCount which defines the number of items the list will contain. Using the ListView.builder approach ensures that only the widgets that are actually visible to the user are being rendered, which optimizes performance and resource usage.
To display data in a ListView widget, you can use the ArrayAdapter class.
The ArrayAdapter class is a built-in class in Android that is used to bind an Array of data to the ListView widget. It converts each item in the Array into a corresponding View that is displayed in the ListView.
For example, if you have an Array of strings, you can create an ArrayAdapter and pass the Array to it. The ArrayAdapter will then create a TextView for each string in the Array and display them in the ListView.
