Welcome to my first article about Flutter package testing. Each week, I will test another package published under pub.dev.
Email Validator
This week’s package provides you with one easy-to-use function to validate an email input. The author mentions that this is a simple (but “correct”) Dart class for email validation without using regular expressions. We’ll come back later to why he calls it correct.
The Purpose
I think the purpose of this package is very clear. For example, if you want to register a user with an email address and a password, you have to verify that the email address is valid. If it’s not, you can give your user a hint that they have to check their email address again for any spelling mistakes. Not all backend systems support email validation while creating a new user. According to your app’s user experience, it’s also much better to help your user when they’ve finished the email address input and want to start filling in a password.
Most of the time, you start searching for an email validation right when you need it. Looking at Stack Overflow, the most upvoted response for this scenario is a complex regex.

Hi there, we encourage authors to share their entire posts here on DEV, rather than mostly pointing to an external link. Doing so helps ensure that readers don’t have to jump around to too many different pages, and it helps focus the conversation right here in the comments section.
If you choose to do so, you also have the option to add a canonical URL directly to your post.
