            case ExtraValidatorDataSource::INPUT_SOURCE:
                return $this->getInputSource()->all();

It seems like getInputSource() must be provided by classes using this trait. How about adding it as abstract method to this trait?

            default:
                return $this->validationData();

The method validationData() does not exist on Laravel\ExtraFieldsValidator\ProvidesExtraFieldsValidator. Did you maybe mean validator()?

        }
    }

    public function getExtraFieldErrorMessage(string $field): string
    {
        return trans('validation.custom.extra_field', ['attribute' => $field]);
    }
