Using StateNotifier also works perfectly. Well, until recently.. then I found out that updating a setting value not only updates the UI that listens to that value, but also updates other parts of the UI that don't listen to it, but listen to other setting values in the same state. I hope you get what I mean from the last sentence.

To make it clear, let me show you a very simple demonstration.

We'll make 2 switches: Switch A and Switch B.
Switch A will build Box A, and should not build Box B.
Switch B will build Box B, and should not build Box A.
