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.
