I have the same issue and I read about other users with the same issue. Latest version that doesn't have the problem is 0.5.5 for me.

Problem is, with this version I can't build the apk, I get this error:

````
FAILURE: Build failed with an exception.

I got the same errors for both libraries (tested separately as well).

cloud_firestore: ^0.12.9+5
firebase_auth: ^0.14.0+5

The same behaviours for the same steps to reproduce.

Using the value provided on the instruction page causes crash, try this:

    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-0000000000000000~0000000000"/>
