Returning Data from a Screen

Explore how to return data from a screen in Flutter using Navigator.pop() and await.

Navigate to the Second Screen

In your first screen (the screen from which you want to receive data), use Navigator.push() to navigate to the second screen.

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

Send Data Back from the Second Screen

In the second screen, when you want to return data to the first screen, use Navigator.pop() with the data you want to pass back.

Navigator.pop(context, "Data to be returned");

Handle the Returned Data in the First Screen

In the first screen, use await with Navigator.push() to get the data returned from the second screen.

var result = await Navigator.push(
  context,
  MaterialPageRoute(
    builder: (context) => SecondScreen(),
  ),
);

if (result != null) {
  // Handle the returned data here
  print("Returned data: $result");
}

Step 4: Complete the Second Screen Navigation

Make sure to use Navigator.pop() to complete the navigation in the second screen. This will return control to the first screen.

// Use Navigator.pop() to complete the navigation
Navigator.pop(context, "Data to be returned");
