Closing this as duplicate of #210

Closing this as duplicate of #210

Why close this issue as a duplicate of a CLOSED issue when the problem is still ongoing and not fixed?

[juliansteenbakker]

My bad, i thought it was open.

Hey, how's this issue going? I'm facing the issue and have not found any fix or workaround yet!

[dakr0013]

@nombrekeff adding custom backup rules fixed the error for me:

1. i added android:fullBackupContent="@xml/my_backup_rules" to application tag in AndroidManifest.xml
2. i created the file my_backup_rules.xml in main/res/xml with following content:

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content>
    <include domain="sharedpref" path="."/>
    <exclude domain="sharedpref" path="FlutterSecureStorage"/>
</full-backup-content>

see also https://pub.dev/packages/flutter_secure_storage#configure-android-version and https://developer.android.com/guide/topics/data/autobackup#IncludingFiles

@dakr0013 thanks, I will try that! I've seen this solution a lot, so everything points that it works!

[nombrekeff]

The solution @dakr0013 told me did not work for me, I'm still facing the issue. Any updates on this?

[dala00]

I temporary fixed. First, readAll always throws exception. So use read only.

And when a key doesn't exist (or no data exist?), exception is thrown. So catch.

    try {
      return await storage.read(key: myKey);
    } catch (e) {
      return null;
    }

And targetSdkVersion 30 may cause this. (Or android version?)

Still the same issue with Pixel4a Android 12 and flutter_secure_storage 5.0.2

"PlatformException(Exception encountered, read, javax.crypto.BadPaddingException: error:1e000065:Cipher functions:OPENSSL_internal:BAD_DECRYPT"

Problem occurs with read AND readAll
