The main problem is caused by the time_machine package, I commented a temporary fix in the corresponding issue: https://github.com/Dana-Ferguson/time_machine/issues/44.

However, even when overriding the meta package dependency, most of the tests still break, mainly because of the null-safety framework changes. I need to look into this more, for now we can just use Flutter 1.22.

student-hub / acs-upb-mobile

Tests break with Flutter 1.23 #90
