observer.navigator == null is not true

So this error keep happening when I have more that one MasterDetailScaffold in the widget tree. Somehow its almost as if their instances are not separate.

To recreate this issue I used the example app from the repo and added an action to the app the that routes to another section of the example that also has a MasterDetailScaffold then it breaks.

I was wondering if anyone knows what im doing wrong, of if what I could do to fix this issue as it has been persisting for long while now.

Yes.

It's been a while since I've looked at the implementation but off-memory, it was built more on the assumption that there's only one as it's typically the pages within the within the nested navigator that change whilst the menu in the "master pane" remains the same
