How to change state from StatefulWidget object in flutter?

Posted by Andre Scott | Updated on

Want to change state from StatefulWidget object in flutter? Accessing another widget state requires more work than just rebuilding it. To access the state you should use keys or you should add special methods in the widget itself.

In this case, where the star is rebuilt no matter what, it is even better and simpler to use plain stateless widgets because the selected state can be provided by the parent in the moment of rebuilding.

And since the state is stored in the parent widget, I think it is better no to store it as wall in each one of the individual stars.

Next is a very simple solution that follows that idea. But yes, it still rebuilds the stars.
