Fortunately, the answer is YES.
To help you with this, there's Reactive Forms — a package inspired by Angular's reactive forms that boosts Flutter's native form management.

Reactive Forms, through a simple interface, allows you to implement complex validation rules in a simple, reusable, and intuitive way. Moreover, through its API, it lets you not only use the built-in form fields but also implement your own, whether simple or complex.

In short, it saves us time and sanity.
