call a file by Listtile

Question

I have an apparently simple doubt (difficult for me as a beginner), but I created a navigation Drawer, and in this Drawer has the Listtile, I need to know how to call a file by this list.

ListTile(
              title: Text('Calculadora'),
              onTap: () {

                Navigator.pop(context);
              },

I have a file "Calculator.dart", but do not know what function I put to change the pay.

Answer 1

Here are some examples how to navigate between pages, note that there are several ways depending on your use.

I can not know for sure how is the implementation of your navigation, but a possible solution would be:

Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => Calculator()),
);

See a basic example running here:
