Flutter android release stuck on splash screen

Question

Flutter android release build is stuck on splash screen.

I have tried by cleaning project flutter clean. But still it got stuck on splash screen. I have also used WidgetsFlutterBinding.ensureInitialized(); before executing the runApp(). Still it stuck on splash screen. Also haven't found error logs that can be resolved.

It is not happening with debug version or when I run with flutter run --release. The app is running smoothly in flutter run --release.

I'm using flutter 1.22.0 & VSCode 1.49.3. Testing & releasing for android.

I'm stuck with this last 3 days. It would be very helpful if anyone can help me.

try with the latest version of flutter and run `flutter run --release -v` to see the logs. — Abhishek Ghaskata, Oct 03 '20 at 05:25
The app is not stucking on splash screen when running with `flutter run --release`. It is only stucking on splash screen in release apk... — Anirban Das, Oct 03 '20 at 05:52
are you fetching any data from the internet? IF yes, have you added the internet permission to the android manifest file? — OMi Shah, Oct 03 '20 at 07:04

A permanent solution to @Anirban Das answer is to edit your release buildTypes on app/build.gradle with shrinkResources false as the following:

buildTypes {
    release {
        shrinkResources false
        minifyEnabled false
        signingConfig signingConfigs.release
    }
}

I was using some Lottie files (from assets) on the splash screen (of flutter, not the native one). Adding only `shrinkResources false` helped me resolve this issue in my case. – Mahan Vyakti May 31 '21 at 17:58
I am facing a similar issue. This is happening with Flutter 2.2.3. I integrated a native SDK for ads after which the home screen stopped showing and the app is getting stuck on a black screen. Tried all of the above but none of them has helped resolve the issue – WeSay Solutions Jul 23 '21 at 16:12
I'm facing kind of same issue. but this problem is happening in my case when an app is not used for some days(approx a week). is it gonna solve the problem? or i have made some other mistake? – Safiul islam May 29 '23 at 09:35

I solved this problem by

flutter build apk --no-shrink --split-per-abi

Don't know why, but I think code default shrinking was the problem.

This did not work for me, I had to downgrade to gradle 6.1.1 and buildtool 4.0.2 – nilsmagnus Oct 28 '20 at 09:25

Add android:allowBackup="false" tag inside your <application> object in your app manifest
