Flutter’s pull-to-refresh (swipe-to-refresh) feature lets users pull down on a scrollable list to fetch updated data

. In this beginner-friendly tutorial, we wrap a ListView in Flutter’s built-in RefreshIndicator widget. When the user pulls down far enough, an animated circular spinner appears, and the onRefresh callback is triggered. Inside that callback we simulate a network load (using Future.delayed) before updating the list, demonstrating how the refresh completes with a smooth loading animation.

We also customize the UI style of the refresh indicator (for example, changing its color and stroke width) to create a unique look. By following along, you’ll learn how to add seamless pull-to-refresh functionality and a custom loading animation to your Flutter app. This quick tutorial clearly shows how to implement and style the pull-to-refresh in a ListView, making your mobile app’s UI more interactive and polished—perfect for Flutter beginners learning mobile UI development.
