Bug with Regex Form Validation

Current Behavior

I'm reporting an issue with the regex validation in our form widget.

The email and password fields are failing to validate correct input. For example, an email like my.email@test.com and a password like StrongPass123! are being rejected, even though they match the regex rules.

Here are the regex patterns we're using:

Email: /^[a-zA-Z0-9._]+@[a-zA-Z0-9]+.[a-zA-Z]+$/

Password: /^(?=.[A-Z])(?=.[a-z])(?=.\d)(?=.[!@#$%^&*(),.?":{}|<>]).{8,}$/

It seems the validation logic in the widget isn't applying the patterns correctly

Hi!

I'm sorry you're experiencing this issue. Since you haven't uploaded the bug report code, I wasn't able to review your project specifically. However, based on the examples you shared, it seems the errors are related to the regular expressions (regex) you're using.

To allow the email and password examples you mentioned, you could use the following expressions in your form:

Email: ^[\w.-]+@([\w-]+.)+[a-zA-Z]{2,}$
Password: ^(?=.[A-Z])(?=.[a-z])(?=.\d)(?=.[!@#$%^&*()_+-=[]{};:'\|,.<>/?]).{8,}$

Here's some documentation in case you'd like to dive deeper: https://docs.flutterflow.io/resources/forms/form-validation/#2-adding-validations

I hope this helps!
Best regards.
