+## Firebase Configuration

+To configure firebase, run `flutterfire`.
+
+First, activate `flutterfire`:
+
+```shell
+dart pub global activate flutterfire_cli
+```
+
+The configure it:
+
+```shell
+flutterfire configure --overwrite-firebase-options --platforms=web,macos,android --project=fluttergenui
+```
+
+You can configure the project on the Google Cloud Console for the [FlutterGenUI project](https://pantheon.corp.google.com/welcome?inv=1&invt=Ab4FMw&project=fluttergenui).
