Flutter keeps throwing an error after adding local navigator

[Lasslos]

Hey Guys,

the title descries my problem. I made a few differences in the way that my routes work, since I wanted a more object-oriented way. I don't know what the f*** is going on, since I can't find any relevant differences.
