}My flutterconfig-dart.json file:

"useEnumExtension": true
}Command line used for generation
java -jar .\openapi-generator-cli-4.2.2.jar generate -i .\openapi.json -g dart -o .\openapi-test -c flutterconfig-dart.json
Steps to reproduce
Just generate the code using the command line, and then open any model dart files, such as:
\openapi-test\lib\model\person.dart
There you can see that the constructor of the Person class is Person(); So no instantiation of the field age takes place.
So in order to use the Person class you would need to do:
Person person = new Person();
person.age = new AgeValue(); // This would be totally unnecessary, with the fix I suggest below.
Imagine how big this problem is, if you wanted to instantiate a class with deeply nested field of other classes.
Suggest a fix
Extend all generated constructors to instantiate all fields.
