@Papatee04 Hey. The validators related logic is in a separate repo. Add the form_builder_validators: ^9.0.0 to the pubspec.yaml.

For more context: https://pub.dev/packages/form_builder_validators

[deandreamatias]

What method do you try use? ´FormBuilder.of(context).validate()´?
You need use key on FormBuilder to validate the form. Take a look on readme examples

This instruction should be added in the package readme, or endorsed together with this package.
