Warning: Operand of null-aware operation '!' has type 'List<int>' which excludes null.

[thetoster]

After generation of .g.dart for following classes:

@CopyWith()
class MyList {
  final List<int> integers;
  final List<String> strings;
  final List<MyTypeInList> customType;
  final List<dynamic> dynamicType;
  final List<dynamic> expDynamicType;

  MyList({
    required this.integers,
    required this.strings,
    required this.customType,
    required this.dynamicType,
    required this.expDynamicType,
  });
}

@CopyWith()
class MyTypeInList {
  final int val;

  MyTypeInList({
    required this.val,
  });
}

@CopyWith()
class MyOtherInList {
  final String str;

  MyOtherInList({
    required this.str,
  });
}

I got several warnings in console while compiling project:
