Firebase + Flutter sample apps with code snippets, supported by comprehensive articles for each implementation

FlutterFire Samples

This repo is created to contain various sample apps demonstrating the integration of Firebase with Flutter. The final goal is to create something like the Flutter Gallery app, but for Firebase.

Also, the recently changes introduced in Flutter 2 create some confusion, mostly with the beginners, as many other repositories are not yet updated to the latest version. Even FlutterFire plugins got a lot of improvements and most of them support null safety now.

NOTE: This entire repo uses the latest Flutter 2.0 stable release, with null safety enabled, for creating the sample apps.

Plugins

For this project you have to add two plugins:

  • firebase_core: Required for initializing Firebase and using any other Firebase plugins.
  • firebase_auth: For using Firebase Authentication service in Flutter.

The latest version of both these plugins support null safety.

Usage

If you want to try out the this sample app, first you have to create and configure a Firebase project:

  • Clone the project:

    https://github.com/sbis04/flutterfire-samples.git
  • Create a new Firebase project from the console.

  • Configure the Firebase for each platform.

  • Run the app using the command:
