Please see issue Dana-Ferguson/time_machine#5. (Reprinted below)
The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.
Because flutter_native_timezone 1.0.0 requires SDK version >=1.9.0 <2.0.0 and no versions of
flutter_native_timezone match >1.0.0 <2.0.0, flutter_native_timezone ^1.0.0 is forbidden.
So, because flutter_calender depends on flutter_native_timezone ^1.0.0, version solving failed.
Background information: I created date and time API for use in Dart and on Flutter your library can be used to directly get the user's timezone (vs. a heuristic solver which normally works, but can never be guaranteed).

Is it possible to get pubspec yaml updated for Dart 2.0?
Thank you, :)
