Multiple dex files define Lcom/google/firebase/FirebaseException;

Hi,

I can't build app when I add to this line on _project/android/app/build.gradle_

apply plugin: "com.android.application"
//apply plugin: 'com.google.gms.google-services' // <-This line Add this line for analytics
import com.android.build.OutputFile

ERROR;

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithDexForRelease'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/google/firebase/FirebaseException;

Please help me,
Thanks
