# The case of assigning the id of PlutoMenuItem.

A unique `id` can be set for `PlutoMenuItem`.
```dart
PlutoMenuItem(
  id: 'unique_id',
  title: 'Menu 1',
)
```

If `PlutoMenuItem` is created in `build` method, you should set a unique `id` for `PlutoMenuItem`.  
Otherwise, when `PlutoMenuBar` is rebuilt, incorrect actions such as flickering or closing of open menus may occur.  
(`id` must be unique throughout the app.)
```dart
class TestWidget extends StatelessWidget {
  const TestWidget({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return PlutoMenuBar(menus: [
      PlutoMenuItem(
        id: 'Menu1',
        title: 'Menu1',
      ),
      PlutoMenuItem(
        id: 'Menu2',
        title: 'Menu2',
      ),
    ]);
  }
}
```

If `PlutoMenuItem` is created only once in a method such as `initState`, there is no need to set `id`.  
Even if `PlutoMenuBar` is rebuilt, `PlutoMenuItem` is reused.  
(The internal `PlutoMenuItem.key` is not changed.)
```dart
class TestWidget extends StatefulWidget {
  const TestWidget({Key? key}) : super(key: key);

  @override
  State<TestWidget> createState() => _TestWidgetState();
}

class _TestWidgetState extends State<TestWidget> {
  late final List<PlutoMenuItem> menus;
  
  @override
  void initState() {
    super.initState();
    
    menus = [
      PlutoMenuItem(title: 'Menu1'),
      PlutoMenuItem(title: 'Menu2'),
    ];
  }
  
  @override
  Widget build(BuildContext context) {
    return PlutoMenuBar(menus: menus);
  }
}
```
