The Firebase Kotlin SDK is a Kotlin-first SDK for Firebase. It's API is similar to the Firebase Android SDK Kotlin Extensions but also supports multiplatform projects, enabling you to use Firebase directly from your common source targeting iOS, Android or JS.

Available libraries

The following libraries are available for the various Firebase products.

Service or Product Gradle Dependency API Coverage
Authentication dev.gitlive:firebase-auth:1.4.2 80%
Realtime Database dev.gitlive:firebase-database:1.4.2 70%
Cloud Firestore dev.gitlive:firebase-firestore:1.4.2 60%
Cloud Functions dev.gitlive:firebase-functions:1.4.2 80%
Cloud Messaging dev.gitlive:firebase-messaging:1.4.2 0%
Cloud Storage dev.gitlive:firebase-storage:1.4.2 0%
Remote Config dev.gitlive:firebase-config:1.4.2 20%

Kotlin-first design

Unlike the Kotlin Extensions for the Firebase Android SDK this project does not extend a Java based SDK so we get the full power of Kotlin including coroutines and serialization!

Suspending functions

Asynchronous operations that return a single or no value are represented by suspending functions in the SDK instead of callbacks, listeners or OS specific types such as Task, for example:

suspend fun signInWithCustomToken(token: String): AuthResult

It is important to remember that unlike a callback based API, wating for suspending functions to complete is implicit and so if you don't want to wait for the result you can launch a new coroutine:

//TODO don't use GlobalScope
GlobalScope.launch {


Asynchronous streams of values are represented by Flows in the SDK instead of repeatedly invoked callbacks or listeners, for example:

val snapshots: Flow<DocumentSnapshot>

The flows are cold, which means a new listener is added every time a terminal operator is applied to the resulting flow. A buffer with the default size is used to buffer values received from the listener, use the buffer operator on the flow to specify a user-defined value and to control what happens when data is produced faster than consumed, i.e. to control the back-pressure behavior. Often you are only interested in the latest value received, in this case you can use the conflate operator to disable buffering.

The listener is removed once the flow completes or is cancelled.


The official Firebase SDKs use different platform-specific ways to support writing data with and without custom classes in Cloud Firestore, Realtime Database and Functions.

The Firebase Kotlin SDK uses Kotlin serialization to read and write custom classes to Firebase. To use Kotlin serialization in your project add the plugin to your gradle file:

plugins {
    kotlin("multiplatform") // or kotlin("jvm") or any other kotlin plugin
    kotlin("plugin.serialization") version "1.5.30"

Then mark you custom classes @Serializable:

data class City(val name: String)

Instances of these classes can now be passed along with their serializer to the SDK:

db.collection("cities").document("LA").set(City.serializer(), city, encodeDefaults = true)

The encodeDefaults parameter is optional and defaults to true, set this to false to omit writing optional properties if they are equal to theirs default values.

You can also omit the serializer but this is discouraged due to a current limitation on Kotlin/JS and Kotlin/Native

Server Timestamp

Firestore and the Realtime Database provide a sentinel value you can use to set a field in your document to a server timestamp. So you can use these values in custom classes they are of type Double:

data class Post(val timestamp: Double = ServerValue.TIMESTAMP)

Default arguments

To reduce boilerplate, default arguments are used in the places where the Firebase Android SDK employs the builder pattern:

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
        .setDisplayName("Jane Q. User")

        .addOnCompleteListener(new OnCompleteListener<Void>() {
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "User profile updated.");


user.updateProfile(displayName = "state", photoURL = "CA")

Named arguments

To improve readability functions such as the Cloud Firestore query operators use named arguments:

citiesRef.whereEqualTo("state", "CA")
citiesRef.whereArrayContains("regions", "west_coast")


citiesRef.where("state", equalTo = "CA")
citiesRef.where("regions", arrayContains = "west_coast")

Operator overloading

In cases where it makes sense, such as Firebase Functions HTTPS Callable, operator overloading is used:

    val addMessage = functions.getHttpsCallable("addMessage")
    //In the official android Firebase SDK this would be addMessage.call(...)
    addMessage(mapOf("text" to text, "push" to true))


The Firebase Kotlin SDK provides a common API to access Firebase for projects targeting iOS, Android and JS meaning you can use Firebase directly in your common code. Under the hood, the SDK achieves this by binding to the respective official Firebase SDK for each supported platform.

Accessing the underlying Firebase SDK

In some cases you might want to access the underlying official Firebase SDK in platform specific code, for example when the common API is missing the functionality you need. For this purpose each class in the SDK has android, ios and js properties which holds the equivalent object of the underlying official Firebase SDK.

These properties are only accessible from the equivalent target's source set. For example to disable persistence in Cloud Firestore on Android you can write the following in your Android specific code (e.g. androidMain or androidTest):

  Firebase.firestore.android.firestoreSettings = FirebaseFirestoreSettings.Builder(Firebase.firestore.android.firestoreSettings)

NPM modules

If you are building a Kotlin multiplatform library which will be consumed from JS code you may need to include the SDK in your package.json, you can do it as follows:

"dependencies": {
  "@gitlive/firebase-auth": "1.4.2",
  "@gitlive/firebase-database": "1.4.2",
  "@gitlive/firebase-firestore": "1.4.2",

  "@gitlive/firebase-storage": "1.4.2",
  "@gitlive/firebase-messaging": "1.4.2",

  • SDK Setup Instructions

    SDK Setup Instructions

    I have managed to setup my multiplatform project with this library for Android with no issues and it works great so far! However, iOS is giving me the following error when I try to build the app

    ld: framework not found FirebaseFirestore

    which I believe is similar to some of the other issues I've seen in this repo.

    Would it be possible to include working setup instructions for iOS?

    My setup for Android is exactly the same as the usual Firebase guide so I imagine iOS would be the same but I'm probably missing an important step somewhere in between. I should also mention that I have a multi-module project and Firebase is setup as a standalone module to be linked to the rest of the app.

    Thanks very much for building the SDK and I'm hoping to have iOS working the same way as Android 🙏

  • Add sealed classes support to serialization

    Add sealed classes support to serialization

    Could you add support of "sealed" class to the FirebaseDecoder.structureDecoder and FirebaseEncoder.structureEncoder functions?

    I would try it with some think like this:

    fun FirebaseEncoder.structureEncoder(descriptor: SerialDescriptor, @Suppress("UNUSED_PARAMETER") vararg typeParams: KSerializer<*>): CompositeEncoder = when(descriptor.kind) {
        StructureKind.LIST, PolymorphicKind.SEALED -> mutableListOf<Any?>()
            .also { value = it }
            .let { FirebaseCompositeEncoder(shouldEncodeElementDefault, positiveInfinity) { _, index, value -> it.add(index, value) } }
        StructureKind.MAP -> mutableListOf<Any?>()
            .let { FirebaseCompositeEncoder(shouldEncodeElementDefault, positiveInfinity, { value = it.chunked(2).associate { (k, v) -> k to v } }) { _, _, value -> it.add(value) } }
        StructureKind.CLASS,  StructureKind.OBJECT -> mutableMapOf<Any?, Any?>()
            .also { value = it }
            .let { FirebaseCompositeEncoder(shouldEncodeElementDefault, positiveInfinity) { _, index, value -> it[descriptor.getElementName(index)] = value } }
        else -> TODO("The firebase-kotlin-sdk does not support $descriptor for serialization yet")

    This case is optimized for plain Kotlin.

    Unfortunately, I also have some building problems too, so I cannot implement them myself

    There seems to be an issue with a missing AAR file again in the 1.4.0 release as happened with the 1.3.0 release https://github.com/GitLiveApp/firebase-kotlin-sdk/issues/185. I'm guessing it's the same issue.

    A few comments for the changes I made... I noticed the existing project convention was androidAndroidTest for the source folders, but I didn't see them getting used. I've renamed them to androidTest to follow the standard convention. Subsequently, I see failing tests now. Some help here might be warranted.

  • ClassCastException when deserialising sealed class from Firestore in KotlinJS

    ClassCastException when deserialising sealed class from Firestore in KotlinJS

    I'm trying to serialise/deserialise the following model into Firestore on KotlinJS with nodeJs() target, which is correctly written to Firestore, along with its generated type.

    data class ApiSearchSession(
        val id: String,
        val state: ApiState
    sealed class ApiState {
        object Searching : ApiState()

    I'm writing this to Firestore like this

    val document = firebaseFirestore
                data = searchSession.toApiSearchSession(),
                encodeDefaults = true

    However, when deserialising I'm getting a ClassCastException. My deserialisation code is

    val document = firebaseFirestore
            return if (document.exists) {
                val apiSearchSession: ApiSearchSession = document.data()
            } else {

    Am I missing something? I've tried serialising the above to/from Strings with kotlinx.serialisation and it works as it should which lead me to think it's an SDK issue here. I'm on version 1.6.2 of the SDK.

The app is composed of 2 screens, first is the profile screen, it has the user_name and address pinned at the top and then it lists all of this user’s albums. When you press on any album it navigates to the second screen which is an album details screen that contains list of the images in an recyclerview grid. Also you have search bar that you can filter within the photos album by the image title.
