FATAL EXCEPTION: com.it_nomads.fluttersecurestorage.worker

Hello,

I just updated our app to flutter 3.24.1 and flutter_secure_storage 9.2.2, but when I run the app in release mode I get:

Did anybody encounter this or is there a fix for it? Are there any specific proguard rules I should add?

The error appears whenever I call a flutter secture storage method.

Thanks

Just tried to build with minifyEnabled false and then it works perfectly fine.

Tried to add

-keep class androidx.security.crypto.** { *; }
-keep class com.it_nomads.fluttersecurestorage.** { *; }

to the proguard rules, but that does not seem to be enough in minify mode.

I also have the same error with the device SM-S918B

[juliansteenbakker]

Could you please try again with version 9.2.3 or with version 10.0.0-beta.1? If the issue still exists, please let me know so i can look into it.

[clauziere]

What is the conclusion on this issue ? Tried to use the beta version but the same thing happens.

For now we added this rule to the proguard file: -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); }
