final emailRegex = RegExp(r'^[^@]+@[^@]+\.[^@]+');
No, please don't use this regex to validate email. It's wrong. The shortest regex to validate an RFC822 email address is about 2400 characters, and is given in https://www.ex-parrot.com/pdw/Mail-RFC822-Address.html. Anything shorter is WRONG, unless you're using a grammar, as package:email_validator properly does. Use that for Dart/Flutter please.
