Minimal code example

Code sample ```dart FormBuilderValidators.username( minLength: 4, maxLength: 15, allowNumbers: true, allowSpecialChar: false, ); ```

Current Behavior

When I input this string:
abc1

I got error:
Username cannot contain special characters.

Expected Behavior

The validation should pass.

Steps To Reproduce

  1. Create a text field with username validator.
  2. Run flutter run -d linux.
  3. Input "abc1" to the text field.
  4. Trigger form validation.
  5. See error "Username cannot contain special characters."
