I use sdk version >2
when use jwt it conlick below
Running "flutter packages get" in mobile-cockpit-ket-app...
The current Dart SDK version is 2.1.0-dev.1.0.flutter-ccb16f7282.

Because kpi depends on jwt any which requires SDK version <2.0.0, version solving failed.
pub get failed (1)
Process finished with exit code 1

@denchaihos: Unfortunately package:jwt seems to be not compatible with Dart 2. We'll have soon a release that will mark it as such.

I'm moving this to the repository of the package, and maybe the author could comment on his plans to update it.
