I Want to send data to one page and display another page in flutter

Question

I am building a flutter app in which on click of a Gridview Cell I want to display a new page and send the id of the grid cell to a different page, other than the display page. How to do that with Navigator

Answer 1

You just pass the content to the next page via its constructor. The Gridview Cell has an onClick handler I think, if not you can wrap it using a GestureDetector and use the onTap method there and do something like that:

onClick: () => {
  Navigator.of(context).push(
    MaterialPageRoute(
      builder: (context) => SecondPage(id),
    ),
  );
}

where id is a variable stored in the GridviewCell. It comes down to how you structure the data in the widget really.
