flutter do changes upon page gets pop

Question

I have Page1 and Page2.

Page 1 is my base page and I am doing Navigator.push for Page2. After finishing my logic in Page2, I will do Navigator.pop() to return back to Page1.

How will I know that Page1 has become the main page visible to user?

I have tried ModalRoute.of(context).isCurrent but I only want to know when Page2 has pop from Page1.

Answer 1

You can await for the Page1 to finish and pass some data is required from the Page2 to make sure Page2 has been popped from the Navigator stack.

On Page1

bool result = await Navigator.push(context,..);

On Page2

Navigator.pop(context,"some data");

Then your result will hold value "some data" if it's on the Page1.You can similarly pass a boolean or other required data and compare it to know if the Page2 has been popped.
