Resolving the Flutter Android Release Build Stuck on Splash Screen Issue

If you're a Flutter developer, you may encounter a frustrating issue where your Android release build gets stuck on the splash screen. This problem can be particularly perplexing, especially since it often does not occur in debug mode or during direct runs using the command flutter run --release. If you're currently facing this issue, you're not alone. Many developers have also reported their apps freezing on the splash screen during the release build, and this guide will walk you through a solution to get your application up and running smoothly.

Understanding the Problem

The splash screen is typically the first screen your users see when they launch your app. When the application freezes on this screen, it can lead to a poor user experience and can prevent your users from accessing your app entirely. Common practices, like cleaning your project with flutter clean and initializing WidgetsFlutterBinding, often do not resolve the issue.

The problem introduces a frustrating challenge, particularly if you've been working on it for days without a solution.

Key Points to Know:

The issue arises in the release build, but debugging works fine.

Basic troubleshooting methods may not yield results.

No error logs are available to point out the problem.

Solution: Building the APK with Specific Flags

After exploring various potential fixes, many developers, including those who faced similar issues, have found a particular solution that resolves the stuck splash screen problem. The quick fix is to build your app with specific flags that bypass a common pitfall.

Steps to Resolve the Issue:

Open Your Terminal: Make sure you're in the root directory of your Flutter project.

Run the Build Command: Use the following command to build your APK:

--no-shrink: This flag disables the default code shrinking that Flutter applies during the build process. It seems that code shrinking might be the culprit causing your app to hang on the splash screen.

--split-per-abi: This flag creates separate APKs for different CPU architectures, making your APKs more optimized.

Test Your App: Once the build completes, install the APK on your Android device and check if the issue is resolved.

Conclusion

The Flutter Android release build getting stuck on the splash screen can be a vexing problem, but the solution is quite straightforward. By building your APK with the flags --no-shrink and --split-per-abi, you can effectively mitigate this issue and provide a smooth user experience.
