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"),
));flutter snackbar
final snackBar = SnackBar(
content: const Text('Yay! A SnackBar!'),
action: SnackBarAction(
label: 'Undo',
onPressed: () {},
),
);
ScaffoldMessenger.of(context).showSnackBar(snackBar);flutter snackbar duration
ScaffoldMessenger.of(context).showSnackBar(
SnackBar(
duration: const Duration(milliseconds: 4000), // default 4s
content: const Text('Awesome Snackbar!'),
),
);snackbar flutter
ScaffoldMessenger.of(context).showSnackBar(
SnackBar(
duration: const Duration(milliseconds: 5000),
content: const Text('Awesome Snackbar!'),
),
);snackbar in flutter
final snackBar = SnackBar(content: Text('Yay! A SnackBar!'));
// Find the ScaffoldMessenger in the widget tree
// and use it to show a SnackBar.
