For Flutter plugins for other Firebase products, see

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and Pull Requests are most welcome!

Recent versions (0.3.x and 0.4.x) of this plugin require extensible codec functionality that is not yet released to the beta channel of Flutter. If you're encountering issues using those versions, consider switching to the dev channel.

Setup #

To use this plugin:

  1. Using the Firebase Console, add an Android app to your project: Follow the assistant, download the generated google-services.json file and place it inside android/app. Next, modify the android/build.gradle file and the android/app/build.gradle file to add the Google services plugin as described by the Firebase assistant. Ensure that your android/build.gradle file contains the as described here.
  2. Using the Firebase Console, add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner. Don't follow the steps named "Add Firebase SDK" and "Add initialization code" in the Firebase assistant.
  3. Add cloud_firestore as a dependency in your pubspec.yaml file.

Usage #

import 'package:cloud_firestore/cloud_firestore.dart';

Adding a new DocumentReference:

  .setData({ 'title': 'title', 'author': 'author' });

Binding a CollectionReference to a ListView:

class BookList extends StatelessWidget {
  Widget build(BuildContext context) {
    return new StreamBuilder<QuerySnapshot>(
      stream: Firestore.instance.collection('books').snapshots(),
      builder: (BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
        if (!snapshot.hasData) return new Text('Loading...');
        return new ListView(
          children: document) {
            return new ListTile(
              title: new Text(document['title']),
              subtitle: new Text(document['author']),

Performing a query:

    .where("topic", isEqualTo: "flutter")
    .listen((data) =>
        data.documents.forEach((doc) => print(doc["title"])));

Running a transaction:

final DocumentReference postRef = Firestore.instance.document('posts/123');
Firestore.instance.runTransaction((Transaction tx) async {
  DocumentSnapshot postSnapshot = await tx.get(postRef);
  if (postSnapshot.exists) {
    await tx.update(postRef, <String, dynamic>{'likesCount':['likesCount'] + 1});
