# \[Flutter] Navigator Pop時回傳資料

```
_navigateAndDisplaySelection(BuildContext context) async {
    // Navigator.push returns a Future that will complete after we call
    // Navigator.pop on the Selection Screen!
    final result = await Navigator.push(
      context,
      MaterialPageRoute(builder: (context) => SelectionScreen()),
    );

    // After the Selection Screen returns a result, hide any previous snackbars
    // and show the new result!
    Scaffold.of(context)
      ..removeCurrentSnackBar()
      ..showSnackBar(SnackBar(content: Text("$result")));
  }
```

```
 Navigator.pop(context, 'Nope.');
```
