Data is lost after app reinstall on Android (even with allowBackup=true)

[EricFrancischett]

I am experiencing an issue where the stored data in flutter_secure_storage is lost after reinstalling the app on Android. I have already ensured that android:allowBackup="true" is set in my AndroidManifest.xml, but the issue persists.

I found a similar issue reported here: #817, but I didn't see a clear resolution.

Steps to reproduce: Store data using flutter_secure_storage on an Android device. Uninstall the app. Reinstall the app. Try to retrieve the stored data. Expected behavior: The stored data should persist after reinstalling the app, as android:allowBackup="true" should allow it to be restored.

Actual behavior: The data is completely lost after reinstalling the app.

Additional notes: I have already checked my AndroidManifest.xml, and android:allowBackup="true" is correctly set. This behavior is unexpected, as I assumed the data should persist across reinstalls. Could you confirm if this is the expected behavior, or if there is a workaround to ensure data persistence after reinstalling the app?

Thanks in advance!

#817 as @juliansteenbakker said, it doesn't enough to config only AndroidManifest.xml to save ur Shared preferences. ref : https://developer.android.com/identity/data/autobackup i think this will help ur solution
