Firebase UI with Firebase Auth : Twitter not working due to R8

Question

I implement the connection with twitter on my app, everything works properly in debug mode but when I go into release mode (with activation of proguard so) I get this error

 Caused by: java.lang.RuntimeException: Twitter provider cannot be configured without dependency. Did you forget to add 'com.twitter.sdk.android:twitter-core:VERSION' dependency?

Before you ask, yes I put this dependence

maven { url 'https://maven.fabric.io/public' }

and

implementation('com.twitter.sdk.android:twitter-core:3.1.1@aar') {
    transitive = true
}

i have already try to add manually the proguard rules from Firebase-UI that i have found here https://github.com/firebase/FirebaseUI-Android/blob/master/auth/auth-proguard.pro

With proguard it's working fine, we need to wait the patch for R8
