I guess that your Unhandled exception is because the file ./ios/Runner/GoogleService-Info.plist is missing. Did you check it out?

Follow the steps from #5 to #6 to see how create and use this file.

Anyway even with the ./ios/Runner/GoogleService-Info.plist file correctly in place, the App works fine but you'll get this message:

5.15.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure]; (FirebaseApp.configure() in Swift) to your application initialization. Read more: https://goo.gl/ctyzm8.

I check the plugin out and we reach this point:

And that's good ^_^, because that's why with the firebase config file set we run correctly.

Thanks, I put the file GoogleService-Info.plist under ios/Runner, the same log appears:

5.13.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add `[FIRApp configure];` (`FirebaseApp.configure()` in Swift) to your application initialization. Read more: https://goo.gl/ctyzm8.

But it seemed app connected to firebase.
And new error occurs:

5.13.0 - [Firebase/Firestore][I-FST000001] Could not reach Cloud Firestore backend. Backend didn't respond within 10.000000 seconds.
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

The full log is:

5.13.0 - [Firebase/Firestore][I-FST000001] The behavior for system Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK.
To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods:
let db = Firestore.firestore()
let settings = db.settings
settings.areTimestampsInSnapshotsEnabled = true
db.settings = settings
With this change, timestamps stored in Cloud Firestore will be read back as Firebase Timestamp objects instead of as system Date objects. So you will also need to update code expecting a Date to instead expect a Timestamp. For example:
// old:
let date: Date = documentSnapshot.get("created_at") as! Date
// new:
let timestamp: Timestamp = documentSnapshot.get("created_at") as! Timestamp
let date: Date = timestamp.dateValue()
Please audit all existing usages of Date when you enable the new behavior. In a future release, the behavior will be changed to the new behavior, so if you d<…>
