Using Pull to Refresh with Riverpod in Flutter

In modern app development, providing a seamless user experience is essential. One common feature that enhances this experience is the ability to refresh a list of data with a simple pull gesture. This functionality is known as pull to refresh. If you're using Flutter with Riverpod and you're looking to implement this feature on a ListView, you're in the right place. In this guide, we'll walk through the steps needed to achieve this functionality.

Problem Overview

You have a ListView that displays data fetched via a Riverpod provider, and you want to implement a pull-to-refresh feature. The challenge comes in effectively refreshing the data from both your Future Provider and your ChangeNotifierProvider without issues or unnecessary complexity.

Solution Overview

To achieve the pull to refresh functionality, we can leverage the RefreshIndicator widget provided by Flutter. Here’s how you can implement it step-by-step.

Step 1: Understanding Your Providers

Before diving into the implementation, let's clarify your existing providers:

walletBuilderProvider: A ChangeNotifierProvider that watches the dataProvider and builds the wallet model.

dataProvider: A Future Provider that fetches the wallet data.

Since walletBuilderProvider depends on dataProvider, you only need to refresh dataProvider, and it will trigger a refresh of all providers that depend on it.

Step 2: Implementing RefreshIndicator

Now, let’s implement the RefreshIndicator in your ListView. The RefreshIndicator widget requires an async function to refresh the data. Here’s how you can set it up:

Wrap the ListView with RefreshIndicator

Instead of directly returning your WalletList, wrap it with the RefreshIndicator. Here’s the modified code:

Conclusion

Adding a pull to refresh feature in your Flutter application using Riverpod is straightforward. By wrapping your ListView with a RefreshIndicator and refreshing the appropriate provider, you can offer an intuitive and efficient way for users to refresh their data.

Now, you can ensure that your ListView is not just a static display of information but a dynamic interface that responds to user actions. Implement this simple feature and enhance your app's user experience effectively!
