How can I refresh several pages after a database update?

Structure:

Main Page (loads a Model from a local SQLite Database and builds List), click on List item leads to:

-> Detail Page consists of a tab bar
-> Tab Bar Page 1 has some subpages
-> I can change data from the model (like name, age, etc.) in the subpages.

My question is: How can I force to reload all pages up to the Main Page after returning from a subpage to the "Tab Bar Page 1"?

Using an async "onTab"-Button it with the return of the model on the second page (Navigagtion.of(context).pop(newModel)) only refreshes items on the "Tab Bar Page 1" level.

Just add listeners to your database. Whenever something changes, the pages will update automatically
