All dependencies and version numbers are defined in pubscpec.yaml.

Null safety

Our flutterclient uses null safety but not all dependencies use null safety. That is why null safety must be turned off.

Currently (2021-12-15), these packages don't use null safety in master branch:

  • flutter_gauge
  • charts_flutter
  • charts_common
  • flutter_page_indicator
  • flutter_swiper
  • transformer_page_view

and packages without null safety in dev branch:

  • flutter_page_indicator
  • flutter_swiper
  • transformer_page_view
