Flutterfire: 🐛 [flutter_analytics] Parameter does NOT take all the string, only part of it

[tomasbaran]

Steps to reproduce

1. Try to register a user with firebase authentification service e.g. await _auth.createUserWithEmailAndPassword(email: email, password: password);
2. wrap it with try and catch
3. This is how my catch part looks like:

catch (e) {
      _analytics.logEvent(name: 'signup_error', parameters: {'message': e.toString()});
      print(e.toString());
}

1. When I test it and I fill only a few characters in the email field (so no pass, and email not being in a good format)
2. The issue is that it's sending Assertion failed: file:///Users/tomas/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.18.0+1/lib/ instead of what my console gives me which I show in the Expected behavior

Expected behavior

Assertion failed: file:///Users/tomas/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.18.0+1/lib/src/firebase_auth.dart:184:12 password != null is not true

[tomasbaran]

Just thinking out loud. Is there a limit to a String?

[ghost23]

Yes:

https://firebase.google.com/docs/reference/android/com/google/firebase/analytics/FirebaseAnalytics.html#parameters_1

String parameters cannot be longer than 100 characters.

[tomasbaran]

thanks @ghost23 Is there a workaround? Or how am I supposed to get the error message in the analytics that is bigger than 100 characters?

[ghost23]

As far as I know, there is no workaround, because firebase is limiting this on their server-end.

[ghost23]

Since you want to log error messages, perhaps using crashlytics for that instead might be the way to go.

[tomasbaran]

Thanks @ghost23 I was thinking of crashlytics but this is not an app error rather it's what errors users make in my case. So, rather than tracking app errors I want to track user experience errors which doesn't sound like Crashlytics would be a good way to do it IMO.

[ghost23]

I see. Well, I told you everything I know, so ... good luck 😁

[TahaTesser]

Hi @tomasbaran
Looks like this is not supproted from Firebase itself so flutterfire can't do anything about this limit. TYSM @ghost23
Closing, as this isn't an issue with flutterfire itself. If you disagree, please write in the comments and I will reopen it.
Thank you
