Building a Splash Screen with Internet Connectivity Check in Flutter

When developing mobile applications in Flutter, one common requirement is to implement a splash screen that not only looks visually appealing but also performs essential pre-checks, such as ensuring that the device has an active internet connection before proceeding to load the main application. This guide will walk you through the steps required to create a splash screen with a connectivity check using Flutter.

Understanding the Problem

Your mobile app relies on web content or online data, making it critical to confirm internet connectivity before attempting to load anything. Without proper checks, users might encounter frustrating errors or a blank screen if they are offline. This situation can be particularly disheartening, so incorporating a splash screen that handles these checks will enhance the user experience.

Objective

Display a splash screen while checking internet connectivity.

Show a Snackbar or retry option if the internet is unavailable.

Implementing the Solution

We will break down the solution into two key parts: Creating the Splash Page and Implementing a Restart Widget.

1. Creating the Splash Page

Let's create a splash page that will check for the internet connection using the internet_connection_checker package.

Step 1: Install Required Packages

Make sure you have the internet_connection_checker package added to your pubspec.yaml file:

Conclusion

Incorporating a splash screen that checks for internet connectivity before proceeding to load content can significantly improve user experience. This Flutter implementation leverages the internet_connection_checker package to ensure users are aware when they are offline and provides them with easy retry functionality.

By following the steps outlined in this guide, you can build a responsive and user-friendly application that gracefully handles connectivity issues.



By implementing these solutions, you can assure users of a smooth onboarding process as they enter your Flutter app!
