Flutter, send parameter previous screen

I have two screens A and B. I clicked a button from A and open B screen. When opened B screen I choose something and go back to A screen with:

      Navigator.pop(context, MaterialPageRoute(builder: (context) => A(data: data)));

but it doesn't work.

How can go back to the previous screen with data using pop or similar things?

the pop method takes an optional parameter that you can return to the previous screen. You would use it like so:

// In screen A:
final result = await Navigator.push(...); // Here you just push the route like normal

// In screen B:
Navigator.pop(context, data); // Where data is whatever you want to return to screen A

In the above example, result will contain whatever you returned from screen B
