The error you titled with this is not an error. That's a warning. (I edited it so it fits better, for future searchers)

The error you have is a MultiDex failure. You have not enabled multidex, it's in the trace you posted if you look carefully:

Caused by: com.android.tools.r8.utils.AbortException: Error: null, Cannot fit requested classes in a single dex file (# methods: 97445 > 65536)

Do this: https://rnfirebase.io/#android-enabling-multidex
