### Description

I noticed `firebase_options.dart` is not formatted correctly according to `dart format` (i got a built error on the server).

Diff after running dart format:

```
diff --git a/lib/firebase_options.dart b/lib/firebase_options.dart
index 22bbfef6..9c85f9e2 100644
--- a/lib/firebase_options.dart
+++ b/lib/firebase_options.dart
-

```

### Steps to reproduce

### Expected behavior

I'd excpect it to be formatted according to `dart format`
