[firebase_auth_web] _FirebaseErrorWrapper Exception instead of PlatformException when providing wrong password

[xkxeeshankhan]

Flutter for Web, in case of Firebase auth throw _FirebaseErrorWrapper exception instead of PlatformException, so for that we have to use a catch block to handle different scenarios to handle all kind of exception thrown by Firebase auth

SOLUTION
Please change _FirebaseErrorWrapper to PlatformException so its matched the Flutter for Mobile exception handling and are easier to maintain

Error message
The exception that I received is like this:
FirebaseError: The password is invalid or the user does not have a password. (auth/wrong-password)
Type: _FirebaseErrorWrapper

Version:
firebase_auth: ^0.16.0
Scripts:

<script src="https://www.gstatic.com/firebasejs/7.15.1/firebase-app.js"></script> <script src="https://www.gstatic.com/firebasejs/7.15.1/firebase-auth.js"></script>

Hi @xkxeeshankhan
Providing wrong password isn't giving PlatformExcpetion using official example on web

Thank you

Hi @TahaTesser,
Thanks for the clarification but i'm receiving all failures cases in catch block (and i catch is used to handle exceptions) of try catch instead of PlatformException in case of web:

I believe I'm also experiencing this issue. Every error I get from my callable cloud function is a _FirebaseErrorWrapper, which is not a type that I can access to interrogate.

Here is the response JSON payload from my cloud function when I attempt to signup without providing an email address:

{"error":{"message":"No email provided.","status":"INVALID_ARGUMENT"}}

I have a try/catch where I handle any unknown exception (an exception that is not a PlatformException):

print('Unknown exception during user sign up: $exception');
print(' - ${exception.runtimeType}');

Those print statements lead to the following logs:

Unknown exception during user sign up: FirebaseError: No email provided. (invalid-argument)
 - _FirebaseErrorWrapper

The failure information in the JSON is what I expect, but it's being packaged into this inaccessible error type.

Here are my JS includes:

<script src="https://www.gstatic.com/firebasejs/7.15.5/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/7.15.5/firebase-auth.js"></script>
