Hello. I try make an flutter app, but I have an error after installing package flutter_secure_storage. Without this package my app build successfully, but after adding this package I have an error:

For what it's worth: I've run into similar issues, and usually it had something to do with incompatible gradle or Kotling versions or something like that. You might want to open the Android part of your app in Android Studio and attempt an update of gradle. And don't forget to clear all build data. Sorry that I can't be more specific. That's what I did, and it worked somehow...

I'm having a similar issue. Just now (a day later) narrowed it down to flutter_secure_storage, and am now researching a workaround.

Steps to recreate:

1. I created a new app, and it built successfully.
2. I then added flutter_secure_storage: ^9.2.1, and it failed to build with the error below pertaining to path_provider_android. 9.0.0 didn't work either.
3. I removed the dependency, and it built successfully again.

I've tried on channels master and beta. Will try to download Flutter version next.

I found downgrading flutter_secure_storage to 8.1.0 got it working, even after upgrading to the latest version of Flutter (beta channel).

dependencies:
  flutter_secure_storage: ^8.1.0
