Try + Catch User Auth Flutter Dart

[rodnnnney]

Hey guys! I'm pretty new to pocket base and want to know how do you catch errors when dealing with user authentication in Pocket base?

I want to be able to catch errors when users try input their info sign in and display a UI element corresponding to the error they made.

I tried parsing the error like JSON
Getting the status code of the thrown error

This is what I am working with below:

Future<void> signIn(String email, String password) async {
    try {
      final authData =
          await pb.collection('users').authWithPassword(email, password);
      setAuthData = authData;
      notifyListeners();
    } catch (error) {
      print('Error during sign in: $error}');
    }
  }

When I tried get the response type of the error error.response and map it statusCode and handle it from there. Seems like [] operator can't be applied on the error object. However, since the console is printing this, I think it should be possible, the message is telling you what is wrong.

Error during sign in: ClientException: {url: ---/auth-with-password, isAbort: false, statusCode: 400, response: {code: 400, message: Something went wrong while processing your request., data: {identity: {code: validation_required, message: Cannot be blank.}, password: {code: validation_required, message: Cannot be blank.}}}, originalError: null}

All I want is the data{identity:...} and password:{code...}

I couldn't find anything about this in the documentation. Any help or ideas is greatly appreciated.

Seems like [] operator can't be applied on the error object.

I don't understand what do you mean by this.

This is not PocketBase specific but to catch a specific error you can use either is if check inside the catch block or directly filter it before the catch:

try {
  ...
} on ClientException catch(e) {
  // e.response["data"]
}

In general for all available exception fields you can refer to Error handling or the class reference.

If you are still not able to resolve your issue, please paste the exact error.

Thank you for the quick response! I just didn't know you had to specify ClientExepction to access status codes and data etc.
