Handling the menu programmatically
It is possible to handle the menu programatically by using a key. Just create a key and set it in the
keyproperty of the
FabCircularMenu, then use the key to get the current state and open, close or check the status of the menu.
class MyApp extends StatelessWidget {
final GlobalKey fabKey = GlobalKey();
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: RaisedButton(
onPressed: () {
if (fabKey.currentState.isOpen) {
fabKey.currentState.close();
} else {
fabKey.currentState.open();
}
},
child: Text('Toggle menu')
),
floatingActionButton: FabCircularMenu(
key: fabKey,
children: [
// ...
]
)
)
);
}
}
