I fixed the issue. On one screen, there was a ListView whose entries depended on login information. The list items were built in the build method of the widget. Upon logging out and logging in again as someone else, the data that builds the ListView changed and this screen crashed in the background with the exception given above. To fix I put the building of the ListView inside the A more detailed error message could be about the data of a list changing without the widgets changing or something |

The app has a login page, then a screen with a ListView which is populated based on the login. Upon logging out, you are brought back to the login screen and the following exceptions all throw. I wish I had more information but I really have no idea what's going on. I don't even know which widgets in the app are causing this.
