Best practices for using firebase in development and production with react-native-cli

Question

I'm new to React Native and Firebase and decided to improve my knowledge in this regard, I read some articles on interaction and how to connect one to the other, but I can't figure out how to split my app in firebase into dev and prod, because for deva, I want to use collections and logging auth ticks of what I use in development, and when compiling in prod I already used a real collection.

I thought that it could be arranged according to the type of prefixes:

• [Prod] My App
• [Dev] My App

But I see that firebase does not allow me to create another app with the same "Android package name" and, accordingly, I need different SHA1 signatures according to debug.keystore and my [release].keystore, what should I do with this? Can you point me in the right direction, what to look at, what to read to understand this issue, because for the most part what I found is 80% water and 20% what I know myself, but it still does not answer my questions how to be with such separation and how it should behave.

You do not need 2 Google files, one can also work here.

Example:

Create Development and Staging folders inside Android/app/src and put your JSON file there

Add envConfigFiles inside android/app/build.gradle

project.ext.envConfigFiles = [Development: "../../.env.Development",
                              Staging    : "../../.env.Staging",
                              Production : "../../.env.Production"]

Add resValue in defaultConfig resValue "string", "build_config_package", "com.package"

Add flavorDimensions, signingConfigs and productFlavors above buildTypes

 flavorDimensions "default"
    signingConfigs {
        development {
            storeFile file("../keystore/KeyStore")
            storePassword System.getenv("STORE_PASSWORD")
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword System.getenv("KEY_PASSWORD")
        }
        staging {
            storeFile file("../keystore/KeyStore")
            storePassword System.getenv("STORE_PASSWORD")
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword System.getenv("KEY_PASSWORD")
        }
        production {
            storeFile file("../keystore/KeyStore")
            storePassword System.getenv("STORE_PASSWORD")
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword System.getenv("KEY_PASSWORD")
        }
    }
    productFlavors {
        Development {}
        Staging {}
        Production {}
    }

Add these codes inside buildTypes

  debug {
            productFlavors.Development.signingConfig signingConfigs.development
            productFlavors.Staging.signingConfig signingConfigs.staging
            productFlavors.Production.signingConfig signingConfigs.production

after all of these use the below command to build

   "android": "npx nx run-android zype-mobile --mode=StagingDebug",
   "android-prod": "npx nx run-android zype-mobile --mode=ProductionDebug",
