I just attempted to run the following code in DartPad. The code is wrong - I forgot to wrap the Date string in quotes in the final line. Nonetheless, the compiler should not crash.

void main() {
  var list = [
    DateTime.now().add(Duration(days: 3)),
    DateTime.now().add(Duration(days: 2)),
    DateTime.now(),
    DateTime.now().subtract(Duration(days: 1))
  ];

  list.sort((a, b) => a.compareTo(b));
  print(list);
  
  print(DateTime.parse(2019-01-17 00:00:00.000));

}

Dart SDK build number: 2.10.2
OS: Linux, using a proprietary Google corp version
I was opening https://dartpad.dartlang.org on Chrome

Full console output from DartPad included below:

Error compiling to JavaScript:
main.dart:12:35:
Error: Expected ',' before this.
  print(DateTime.parse(2019-01-17 00:00:00.000));
                                  ^^
main.dart:12:35:
Error: Expected an identifier, but got '00'.
  print(DateTime.parse(2019-01-17 00:00:00.000));
                                  ^^
main.dart:
Internal Error: The compiler crashed when compiling this element.

The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.

Please include the following information:

* the name and version of your operating system,

* the Dart SDK build number (2.10.2), and

* the entire message you see here (including the full stack trace
  below as well as the source location above).
