Generative AI integration for Firebase offering model creation, content DSL, multi-turn chat with streaming, safety filters, Vertex AI backend support, and token-estimation tools.
A Kotlin Multiplatform SDK for Firebase, with a focus on Firebase AI (Generative AI) capabilities.
Add to your gradle/libs.versions.toml:
Add to your module's build.gradle.kts:
kotlin {
sourceSets {
commonMain.dependencies {
implementation(libs.firebase.app)
implementation(libs.firebase.ai)
implementation(libs.firebase.auth)
implementation(libs.firebase.firestore)
// Firebase Analytics: see "Firebase Analytics & Advertising ID" below
// (advertising-ID collection is opt-in via firebase-analytics-advertising).
}
}
}
See each module's README for detailed usage and examples:
firebase-analytics does not collect the advertising ID by default — no IDFA on
iOS and no AAID on Android. For most apps this is the right default: analytics keeps
working, and this Firebase Analytics configuration stays off the advertising-ID surface,
so it needs no App Tracking Transparency prompt on its own. (Other SDKs or app code that
use the IDFA / AdSupport APIs may still require App Tracking Transparency.)
commonMain.dependencies {
implementation(libs.firebase.analytics)
}
Only if you need advertising attribution (Google Ads, remarketing audiences, etc.),
additionally depend on firebase-analytics-advertising. It has no API — linking it
is enough to enable advertising-ID collection on both platforms. If you add it, update
your App Store privacy and Play Data safety declarations accordingly.
commonMain.dependencies {
implementation(libs.firebase.analytics)
implementation(libs.firebase.analytics.advertising) // opt-in: enables IDFA / AAID
}
Android note: the advertising ID is not collected by default, but the Play Services measurement libraries still merge the
com.google.android.gms.permission.AD_IDmanifest permission (matching Firebase's own default). If you want a fully clean manifest, add the following to your app manifest — but be aware it also removes for any other SDK that legitimately needs it:
Add your google-services.json to your app module and apply the Google Services plugin:
// build.gradle.kts (project)
plugins {
id("com.google.gms.google-services") version "4.4.2" apply false
}
// build.gradle.kts (app)
plugins {
id("com.google.gms.google-services")
}
Add your GoogleService-Info.plist to your Xcode project and initialize Firebase in your app delegate:
import FirebaseCore
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
func application( : ,
: [.: ]) -> {
.configure()
}
}
