However when this option is not included, The workmanager get initialized successfully at startup in debug mode.

*Extra Information I'm using as target android 9 via USB Debugging.

Any help will be appreciated , and I apologize if I may have broken certain guidelines . My first time reporting a potential bug.

How did you build the Application, and what does your AndroidManifest.xml look like exactly?

RafihYahya commented 2 months ago

The Manifest is basically the default one, with the addition of the following lines:

the build command is the standard flutter build apk

I would like to mention that the problem has been fixed since i removed the allowBackup line, and the application has been working fine. I just wanted to reported it in case someone had similar issues
