[SOLVED] How to catch on promise errors?

Hello again, sorry for bother you guys.

I'm getting this exception when trying to login. I put bad credentials on purpose.

I just want to know how to catch this exceptions, I have added already onError, and make it returns null. But it throws another exception.

This is my code:

TypeScript

  Future? login({required String email, required String password}) {
    try {
      return account
          .createEmailSession(email: email, password: password)
          .then((value) => value)
          .onError((error) => null); // <-- null is marked as error, Want to know with what can I replace that
    } catch (e) {
      print(e);
      return null;
    }
  }

Thanks for your help

TL;DR

The user is experiencing an exception when trying to catch promise errors in their code. They have tried using the `onError` method and returning null, but it throws another exception. They are seeking guidance on how to properly catch the exceptions. Solution: Instead of using `onError`, it is recommended to use `async/await` and `try/catch` for easier code readability. The user should rewrite their code using `async/await` and `try/catch`.

As the error says, you must return a value of the future's type (in this case, session) and can't return null.

Btw, i highly suggest you avoid trying to mix and match then/onError with try/catch. When possible, only use async/await/try/catch as it makes code much easier to read
