Ejemplo 1: cómo mostrar snackbar en flutter
You can show material design snackbars using the following code:
Scaffold.of(context).showSnackBar(SnackBar(
content: Text("New Notification"),
));
In some cases, this will throw an error and it can be resolved using a workaround:
//Declare a GlobalKey
GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();
//Assing this key to the scaffold
Scaffold(
key: _scaffoldKey,
body: ...
)
//finally in the topmost code use this key in the following way
_scaffoldKey.showSnackBar(SnackBar(
content: Text("New Notification"),
));
Ejemplo 2: parte superior de la barra de aperitivos Flutter
RaisedButton(
child: Text('Show Top Snackbar'),
onPressed: () {
Flushbar(
flushbarPosition: FlushbarPosition.TOP,
)
..title = "Hey Ninja"
..message = "Lorem Ipsum is simply dummy text of the printing and typesetting industry"
..duration = Duration(seconds: 3)
..show(context);
},
),
