You should read a little about managing state in flutter.

There are few very good ideas on how to approach this problem.

You can try with fairly simple Scoped Model .

or little bit more confusing Inherited widgets . If you ever used Theme.of(context) or Navigator.of(context) that is basically inherited widget. Just a little more harder to set up properly.
