Now that we have a Stream based on our data models, we can easily share and combine streaming data throughout the widget tree. Open in app Flutter and Firebase E01: Firebase Auth (Email and Password) This is the beginning of Flutter and Firebase series. Import 'package:cloud_firestore/cloud_firestore.dart' import 'package:firebase_auth/firebase_auth.dart' import 'dart:async' import 'models.dart' class DatabaseService Using the service with Provider In the snippet below, we wrap the entire MaterialApp in with a MultiProvider, then listen a Firebase user’s global authentication state. It is mostly syntatic sugar for InheritedWidget, but can also manage Stream subscriptions. However, it can still be a challenge to combine multiple streams and/or share their values in multiple places.Īn even better option is the Provider package. Streams are a bit more complex because we need to explicitly listen to them and dispose of them when done - this can lead to a lot of boilerplate when done manually in a StatefulWidget.Ī better option is to use Flutter’s built in StreamBuilder widget, which automatically manages your stream and gives you a build context. firebasecore: 0.3.4 Firebase Core firebaseauth: 0.8.4+5 Firebase Auth. doSomethingCool ) Īs an alternative, you can break your data into multiple global singletons with the get_it library. Starting with the configuration in the Firebase console, we set the package. Static doSomethingCool () => print ( 'cool' ) } /// Elsewhere in flutter.įlatButton ( child: Text ( Global. Static final FirebaseAnalytics analytics = FirebaseAnalytics () // Helper Methods You can do this by following the steps in the Once you’ve set up your. Static final String title = 'Fireship' // Services Flutter is a wonderful framework for designing applications that can run on different platforms while using a single codebase. Setting up Firebase To get started, you’ll need to create a Firebase project and enable the Authentication service. This ensures that you always know where the value originated and prevents the creation of duplicate instances. Static Global Dataĭart supports global variables, so you can just instantiate objects outside of the widget tree as needed, but keep your code organized and avoid polluting the global namespace.Ī solution that provides organization and also code-readability is to use a dedicated class that defines static properties and methods. When it comes to static values that never change I would highly recommend that you Keep it Simple. If you are building a major project with Flutter & Firebase, consider enrolling in the Full Flutter Firebase Course. However, to take full advantage of this package you must deserialize your raw data to a Dart class. Check on the (Sign In with Apple) capability, then select Continue. Set the bundle Id similar to what we used in the firebase project. In particular, the Provider provides an excellent solution for sharing and managing streams with minimal boilerplate. Enable Apple authentication Apple Setup Open the Identifiers page on the Apple developer website here and click the (+) icon. The following article discusses patterns that I have found exceptionally useful when implementing Firebase User Authentication and Firestore in Flutter.
