Creating a Custom Splash Screen with Image in Flutter
When developing a mobile application, having a visually appealing and functional splash screen is critical for creating a great first impression. However, you may encounter issues with image loading that can leave your splash screen blank. In this guide, we will tackle the problem of implementing a custom splash screen in Flutter, specifically focusing on efficiently loading an image.
The Problem
Let’s say you're building an app that requires asynchronous loading before transitioning to the main screen. To manage this, you might create a splash screen as a widget rather than using the native splash screen. While this approach can work well, it often leads to the challenge of images not loading quickly enough, resulting in a blank splash screen.
Key Issues:
Asynchronous loading: The splash screen appears before the necessary setup is complete.
Slow image loading: If your image takes too long to load, it can make your splash screen look unprofessional.
The Solution
To resolve these issues effectively, we can leverage the precacheImage() function in Flutter to ensure that our image is loaded before the splash screen is displayed.
Step-by-Step Implementation
Here is a structured way to implement a custom splash screen with an image that loads quickly.
1. Pre-caching the Image
First, you need to preload your image using the precacheImage() function. This should be done in your main application widget.

2. Defining the Splash Screen
Now, in your MySplashScreen, you can simply display your image normally.

Additional Tips
Optimize Image Formats: If you are still facing slow loading issues, consider using a JPEG format instead of PNG, as JPEG files generally load faster.
Testing in Release Mode: Make sure to test your application in release mode with the command flutter run --release. The debug mode can sometimes lead to slower performance.
Conclusion
By leveraging Flutter's precacheImage() function and optimizing image formats, you can create a polished and efficient custom splash screen that enhances your app's user experience. Make sure to follow the outlined steps, and you'll have a delightful splash screen in no time!
