firebase 3.2.0

Dart wrapper library for the new Firebase

Build Status

This is a Dart wrapper library for the new Firebase. If you are using Dart to write Flutter apps, consider using the FlutterFire plugins instead.

You can find more information on how to use Firebase on the Getting started page.

Don't forget to setup correct rules for your realtime database and/or storage in the Firebase console.

Authentication also has to be enabled in the Firebase console. For more info, see the next section in this document.

Usage

Installation

Install the library from the pub or Github:

dependencies:
  firebase: '^3.0.0'

Include Firebase source

You must include the original Firebase JavaScript source into your .html file to be able to use the library.

<script src="https://www.gstatic.com/firebasejs/3.9.0/firebase.js"></script>

Use it

import 'package:firebase/firebase.dart' as fb;

void main() {
  fb.initializeApp(
    apiKey: "YourApiKey",
    authDomain: "YourAuthDomain",
    databaseURL: "YourDatabaseUrl",
    storageBucket: "YourStorageBucket");

  fb.Database database = fb.database();
  fb.DatabaseReference ref = database.ref("messages");

  ref.onValue.listen((e) {
    fb.DataSnapshot datasnapshot = e.snapshot;
    // Do something with datasnapshot
  });
}

IO Client

This library also contains an IO client. Create an instance of FirebaseClient and then use the appropriate method (GET, PUT, POST, DELETE or PATCH). More info in the official documentation.

The IO client also supports authentication. See the documentation on how to get auth credentials.

import 'package:firebase/firebase_io.dart';

void main() {
  var credential = ... // Retrieve auth credential
  var fbClient = new FirebaseClient(credential); // FirebaseClient.anonymous() is also available
  
  var path = ... // Full path to your database location with .json appended
  
  // GET
  var response = await fbClient.get(path);
  
  // DELETE
  await fbClient.delete(path);
  
  ...
}

Examples

You can find more examples on realtime database, auth and storage in the example folder.

Dart Dev Summit 2016 demo app

Demo app which uses Google login, realtime database and storage.

Before tests and examples are run

You need to ensure a couple of things before tests and examples in this library are run.

All tests and examples

Create config.json file (see config.json.sample) in lib/src/assets folder with configuration for your Firebase project.

To run the io tests, you need to provide the service_account.json file. Go to Settings/Project settings/Service accounts tab in your project's Firebase console, select the Firebase Admin SDK and click on the Generate new private key button, which downloads you a file. Rename the file to service_account.json and put it into the lib/src/assets folder.

Warning: Use the contents of lib/src/assets is only for development and testing this package.

App tests

No special action needed here.

Auth tests and example

Auth tests and some examples need to have Auth providers correctly set. The following providers need to be enabled in Firebase console, Auth/Sign-in method section:

  • E-mail/password
  • Anonymous

Database tests and example

Database tests and example need to have public rules to be able to read and write to database. Update your rules in Firebase console, Database/Rules section to:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

Warning: At the moment, anybody can read and write to your database. You usually don't want to have this in your production apps. You can find more information on how to setup correct database rules in the official Firebase documentation.

Storage tests and example

Storage tests and example need to have public rules to be able to read and write to storage. Update your rules in Firebase console, Storage/Rules section to:

service firebase.storage {
  match /b/YOUR_STORAGE_BUCKET_URL/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

Warning: At the moment, anybody can read and write to your storage. You usually don't want to have this in your production apps. You can find more information on how to setup correct storage rules in the official Firebase documentation.
