Why does react-native + firebase release crash on android?

Question

Android

I tried to write an application in React-Native, which uses Firestore as a database. When developing, it works, but when I build the release version for android, it crashes when I launch the application.
It crashes at the sight of a line: without it, the application is assembled and launched (of course, without the ability to access the database) Tell me what I'm doing wrong and how to force firebase | firestore work on android. Here is build.gradle:
import * as firebase from 'firebase';

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 27
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

        classpath 'com.google.gms:google-services:4.2.0' // google-services plugin
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '4.7'
    distributionUrl = distributionUrl.replace("bin", "all")
}

Here is app/build.gradlew:
