Summary: The user is experiencing a Stack Overflow error when parsing a date string using DateTime.parse. The error occurs during the sorting of a list of objects that contain a DateTime field.

[eernstg]

Your program is an infinite loop: The creation of a Dto includes the creation of another Dto, unconditionally. Here's the core of the program:

void main() => print(Dto());

class Dto {
  Dto ordre = Dto();
}

You might want to change ordre such that it is a static member rather than an instance member. This is enough to avoid the infinite loop.

I'll close the issue because it is all working as intended. @majornuts, feel free to create new issues if things are still not working as expected.
