Flutter app show White screen in release app mode

White screen in release app

While developing flutter app we have used many packages in flutter application, in some we also add native code and mostly we use images and network connectivity status, all of them are working together in your app.

To analyse actual cause of white screen follow these possible causes

Analyze main.dart file code

Most of time main dart file code stuck due to some additional code added in runApp(), so review it properly in debug mode

Check newly added packages version

Sometimes newly added packages are not working smoothly due to instability with other packages in your code.

Run the app in debug mode and review the code error in the terminal

Most of time App run smoothly in emulator and we skip tiny issues, try to resolve it.

Check for Memory Issues

Check memory leaks, excessive memory usage, or inefficient code, these things sometime not visible in debug mode,try to analyze

Review Native Code

If you are using native code then review it properly

Check Network and Permissions

Sometime network connectivity and API validations, stuck the code , so review the API behaviour if internet is not working,or API response

Flutter Version Compatibility

Sometimes Flutter is not compatible with framework packages so please review it if you change Flutter SDK version

These are some points which may solve app issues
