Creating custom form field widgets in Flutter involves extending the FormField class. This allows developers to define custom behavior, validation, and interaction for specific input fields. By extending FormField, developers can encapsulate the logic associated with the form field, making the code modular and reusable. Utilizing this approach provides a clean and maintainable way to implement complex custom form fields tailored to specific application requirements.
